Vauxhall Adam Won’t Go Into Reverse: Causes, Checks, and Fixes

A Vauxhall Adam that won’t go into reverse can turn an ordinary journey into an awkward puzzle. We may start the car normally, select the forward gears without much trouble, and then discover that reverse feels blocked, grinds loudly, or simply refuses to engage.

It is frustrating, especially when we are parked nose-first against a wall or squeezed into a tight space. Yet a reverse-gear problem does not automatically mean the entire gearbox has failed. Sometimes the cause is surprisingly simple: the clutch pedal may not be travelling fully, the selector mechanism may need adjustment, or cold transmission oil may be making engagement stiff.

Other cases are more serious. A worn clutch, damaged gear linkage, hydraulic failure, or internal gearbox problem can prevent reverse from engaging properly. The key is to pay attention to exactly how the fault behaves.

Does the gear lever feel physically blocked? Does reverse engage when the engine is switched off? Is there a crunching sound? Does the car creep forward even with the clutch pedal pressed down?

Each symptom tells us something useful.

In this guide, we will explore the most common reasons a Vauxhall Adam won’t go into reverse, the checks we can perform safely, the repairs that may be required, and the warning signs that mean it is time to stop experimenting and contact a mechanic.

Why Reverse Gear Can Be More Difficult to Select

Reverse gear works differently from the forward gears in many manual transmissions. Forward gears usually rely on synchronisers to match the speed of rotating gearbox components before engagement. Reverse may not have the same level of synchronisation, depending on the gearbox design.

That means reverse can sometimes resist engagement even when nothing is seriously damaged.

When the car has only just stopped, parts inside the gearbox may still be spinning. If we immediately attempt to select reverse, the teeth may meet in the wrong position, almost like trying to close a zip when both sides are slightly misaligned.

A brief pause can allow the shafts to stop moving.

However, persistent resistance, repeated grinding, or complete failure to engage indicates that something needs attention.

Common Symptoms of a Vauxhall Adam Reverse-Gear Problem

Before diagnosing the cause, we should define the symptom clearly. “It won’t go into reverse” can describe several different situations.

Common complaints include:

  • The gear lever feels blocked before entering reverse.
  • Reverse engages only after several attempts.
  • The gearbox makes a grinding or crunching noise.
  • Reverse works when the engine is off but not when it is running.
  • The lever enters the reverse position, but the car does not move.
  • The gear jumps out when the clutch is released.
  • Reverse is harder to select when the engine is cold.
  • First and reverse are both difficult to engage.
  • The clutch pedal feels soft, low, heavy, or inconsistent.
  • The reverse lights do not illuminate when reverse is selected.

These details help separate a clutch-release problem from a linkage fault or an internal gearbox defect.

First Checks Before Assuming the Gearbox Is Broken

A gearbox replacement is one of the more expensive conclusions we could jump to. Before imagining the worst, we should perform a few basic checks.

Stop the Car Completely

Reverse should only be selected when the Vauxhall Adam is stationary.

Even slight forward movement can make reverse difficult to engage and may produce a harsh grinding sound. Press the brake, bring the car to a complete stop, depress the clutch fully, and wait for two or three seconds before trying again.

Do not force the lever.

If it still resists, return the gear lever to neutral and release the clutch. Press the clutch again, wait briefly, and retry.

Select a Forward Gear First

A useful technique is to select first or second gear before selecting reverse.

With the car stationary:

  1. Press the clutch pedal fully.
  2. Select first gear.
  3. Return the lever to neutral.
  4. Select reverse.

Selecting a forward gear can help stop or reposition the gearbox shafts, allowing reverse to engage more smoothly.

This should not become a permanent ritual. If we need to do it every time, the clutch or selector system may require inspection.

Check the Reverse-Gear Lockout

Depending on the Vauxhall Adam’s gearbox and gear-lever design, selecting reverse may require lifting a collar, pressing the lever downward, or moving it through a specific gate.

A damaged or sticking lockout mechanism can make the lever feel as though it has hit a wall.

Check whether the collar moves freely and whether the lever follows its normal path. Dirt, spilled drinks, worn plastic components, or damage beneath the gear-lever trim can interfere with the mechanism.

The Clutch May Not Be Disengaging Fully

One of the most common explanations for a manual Vauxhall Adam refusing reverse is clutch drag.

When we press the clutch pedal, the clutch should separate the engine from the gearbox. This allows the gearbox input shaft to slow down or stop so that a gear can be selected.

If the clutch does not release fully, the shaft continues spinning. Reverse then resists engagement or makes a crunching noise.

Signs of Clutch Drag

Possible signs include:

  • Reverse crunches even with the clutch fully depressed.
  • First gear is also difficult to select while stationary.
  • The car tries to creep with the clutch pedal on the floor.
  • Gear changes improve when the engine is switched off.
  • The clutch bite point has moved unusually low or high.
  • The pedal feels soft or inconsistent.
  • Pumping the clutch pedal temporarily improves the problem.

These symptoms suggest that the issue may be outside the gearbox itself.

A Simple Engine-Off Test

With the vehicle safely parked and the handbrake applied, switch off the engine and try selecting reverse.

If reverse enters smoothly with the engine off but refuses or crunches with the engine running, the clutch may not be disengaging fully.

This test is not a complete diagnosis, but it is a strong clue.

When the engine is off, nothing inside the gearbox is being driven by the engine. If the lever then moves normally, the selector mechanism may be capable of engaging reverse, while clutch drag is preventing it during normal operation.

Low or Contaminated Clutch Fluid

The Vauxhall Adam may use a hydraulic system to operate the clutch. Hydraulic pressure transfers the movement of the clutch pedal to the clutch-release mechanism.

If the fluid level is low or air enters the system, the clutch may not release far enough.

What Can Cause Low Fluid?

Low fluid may be related to:

  • A leaking clutch master cylinder.
  • A leaking slave cylinder.
  • Damaged hydraulic pipes or connections.
  • A shared brake-and-clutch fluid reservoir that has dropped below the required level.
  • Previous repair work that left air trapped in the system.

A falling fluid level should not simply be topped up and forgotten. Hydraulic fluid does not normally disappear without a reason.

Clutch Pedal Symptoms

A hydraulic problem may make the pedal feel:

  • Soft or spongy.
  • Slow to return.
  • Lower than normal.
  • Inconsistent between presses.
  • Temporarily better after pumping.

If pumping the clutch pedal several times allows reverse to engage, air or pressure loss in the hydraulic system becomes a strong possibility.

Why Hydraulic Faults Should Not Be Ignored

A minor leak can develop into complete clutch failure. We may eventually press the pedal and discover that it no longer disengages the clutch at all.

Because clutch and brake systems may share a fluid reservoir on some vehicles, any unexplained fluid loss deserves prompt professional inspection.

A Worn Clutch Assembly

A worn clutch is often associated with slipping under acceleration, but clutch wear can also create release problems.

The clutch assembly includes several components:

  • Clutch friction disc.
  • Pressure plate.
  • Release bearing.
  • Clutch fork or release mechanism.
  • Dual-mass or conventional flywheel, depending on the engine and configuration.

If the friction disc becomes warped, the pressure plate wears unevenly, or the release mechanism loses movement, the clutch can continue dragging even when the pedal is fully depressed.

Clutch Wear Warning Signs

We may notice:

  • Engine revs rise without equal acceleration.
  • A burning smell after hill starts.
  • Judder when moving away.
  • Noise when pressing or releasing the clutch.
  • A very high bite point.
  • Difficulty selecting first and reverse.
  • Increasingly heavy or rough pedal movement.

Not every worn clutch slips immediately. Some fail by dragging, rattling, juddering, or refusing to release cleanly.

Gear Linkage or Selector Cable Problems

The gear lever is connected to the gearbox through cables, rods, bushes, and selector components. When these parts wear or move out of adjustment, the lever may no longer move the gearbox selector far enough to engage reverse.

Imagine trying to open a door with a handle connected by a stretched cable. The handle moves, but the latch does not travel far enough. A selector cable problem can behave in much the same way.

Symptoms of Linkage Trouble

A linkage or cable fault may cause:

  • A loose or vague gear lever.
  • Difficulty finding certain gears.
  • Reverse and one other gear becoming hard to engage.
  • The lever appearing to enter gear without the gearbox engaging.
  • Sudden changes after clutch or gearbox work.
  • A problem that began after something was disturbed beneath the bonnet.
  • Excessive side-to-side gear-lever movement.

If the selector cables are stretched, damaged, detached, or incorrectly adjusted, reverse may lie just beyond the lever’s available travel.

Worn Bushes and Plastic Components

Small linkage bushes may not look important, but they help maintain precise movement. As these components wear, the gear lever can become sloppy and inaccurate.

The fault may develop gradually. At first, reverse requires a firmer push. Later, it only engages at a certain angle. Eventually, it may disappear completely.

Replacing a small bush or adjusting a selector cable is usually far less dramatic than replacing a gearbox, which is why proper diagnosis matters.

Problems Inside the Gear-Lever Assembly

Sometimes the obstruction is inside the cabin rather than inside the transmission.

The reverse lockout mechanism, gear-lever housing, spring, collar, or plastic guide can become worn or damaged. Foreign objects beneath the trim can also restrict movement.

A coin, broken clip, or piece of plastic lodged beside the lever mechanism may prevent the lever from reaching the reverse gate.

Inspecting the Lever Area

Without dismantling safety-critical parts, we can check whether:

  • The reverse collar lifts fully.
  • The gear lever presses down normally if required.
  • The gaiter is twisted or trapped.
  • The lever feels obstructed in one direction.
  • The movement has recently become unusually loose or stiff.

Removing interior trim should be done carefully. Clips can break easily, and forcing the mechanism may cause more damage.

Cold Gearbox Oil or Incorrect Transmission Fluid

A Vauxhall Adam may feel reluctant to select reverse during cold weather, particularly just after start-up.

Transmission oil becomes thicker when cold. Thick oil creates more resistance between rotating components, making the gear lever feel heavy or notchy.

The issue should normally improve as the vehicle warms up. If it does not, cold oil may only be exposing an underlying clutch or selector problem.

Incorrect Oil Can Affect Shift Quality

Using the wrong gearbox oil can cause:

  • Stiff gear selection.
  • Poor cold shifting.
  • Increased internal wear.
  • Gear noise.
  • Resistance when selecting reverse.
  • Synchroniser problems in the forward gears.

More is not always better. Overfilling can be harmful, while underfilling may starve bearings and gears of lubrication.

Gearbox oil should meet the correct specification for the exact transmission. Guessing by colour or viscosity is not enough.

Possible Gearbox Oil Leak

Signs of a transmission-fluid leak may include:

  • Oil beneath the front of the vehicle.
  • Wetness around driveshaft seals.
  • Oily residue on the gearbox casing.
  • Increasing gearbox noise.
  • Stiffer or rougher gear changes.

Low oil does not usually affect only reverse, but it can contribute to wear and poor selection.

The Reverse Gear Teeth May Be Misaligned

Occasionally, reverse refuses to engage because the gear teeth have stopped face-to-face.

Nothing is necessarily broken. The teeth simply cannot slide together in their current position.

Returning to neutral, briefly releasing the clutch, pressing it again, and selecting a forward gear can rotate the components slightly and allow reverse to engage.

This should happen only occasionally. Frequent tooth-to-tooth blocking may indicate clutch drag, worn selector parts, or internal damage.

Internal Gearbox Damage

Internal gearbox failure is less common than clutch or linkage trouble, but it remains possible.

Reverse relies on gears, shafts, bearings, selector forks, and locking mechanisms. Wear or damage to any of these parts can prevent proper engagement.

Possible Internal Faults

The gearbox may have:

  • Damaged reverse-gear teeth.
  • A worn selector fork.
  • A bent selector component.
  • Damaged engagement teeth.
  • Excessive shaft movement.
  • Worn bearings.
  • Internal debris.
  • A damaged reverse idler gear.
  • A loose or failed retaining component.

These problems normally require gearbox removal and dismantling for confirmation.

Signs the Problem May Be Internal

Internal damage becomes more likely when:

  • Reverse jumps out under load.
  • There is a loud grinding or knocking noise.
  • Metal particles are found in the gearbox oil.
  • The lever reaches the reverse position but drive is not transmitted.
  • The fault remains with the engine switched off.
  • The gearbox has previously run with low oil.
  • The vehicle experienced an impact beneath the engine bay.
  • Several gears are noisy or difficult to engage.

A mechanic should still inspect the external linkage first. We should not condemn the gearbox until the simpler possibilities have been ruled out.

Reverse Engages but the Car Does Not Move

Sometimes the lever appears to select reverse normally, but releasing the clutch produces no backward movement.

This is different from a lever that cannot enter reverse.

Possible causes include:

  • The selector is not actually engaging the gear.
  • A cable has detached or moved out of adjustment.
  • Reverse-gear teeth are damaged.
  • An internal selector fork has failed.
  • The clutch is slipping severely.
  • A driveshaft or differential fault is preventing drive.
  • The gear lever is entering a false position.

If forward gears still move the car normally, the fault may be isolated to reverse engagement. If no gear moves the vehicle, the clutch, driveshafts, differential, or transmission may have suffered a wider failure.

Do not repeatedly rev the engine to force movement. That can overheat the clutch and turn one fault into several.

Reverse Gear Jumps Out

A Vauxhall Adam that enters reverse but jumps back into neutral has a potentially serious issue.

The gear may not be engaging deeply enough because of cable adjustment, linkage wear, or an internal selector problem. Damaged gear teeth or excessive shaft movement can also push the transmission out of gear.

Things We Should Not Do

We should not hold the gear lever forcefully in reverse while moving. This places pressure on the selector mechanism and may accelerate damage.

We should also avoid reversing under heavy throttle. If reverse disengages suddenly, the vehicle may roll unexpectedly.

A gear that jumps out should be inspected promptly.

Could the Clutch Pedal Mat Be the Cause?

It sounds almost too simple, but a floor mat can prevent the clutch pedal from reaching the end of its travel.

A thick, badly positioned, or unsecured mat may slide beneath the pedal. The clutch then feels fully depressed to the driver, but it remains partially engaged.

Check that:

  • The mat is correctly secured.
  • Nothing is trapped behind the clutch pedal.
  • The pedal can travel smoothly to the floor.
  • Carpet or trim is not restricting movement.

This takes only a few seconds and costs nothing to inspect.

Why First and Reverse May Fail Together

First and reverse are commonly the most difficult gears to select when the clutch is dragging because both are selected while the vehicle is stationary.

When the clutch fails to disconnect the engine completely, the gearbox input shaft continues rotating. Selecting first becomes stiff, while reverse may grind because it often lacks the same synchronising assistance as the forward gears.

If both first and reverse are difficult, we should pay particular attention to:

  • Clutch hydraulic pressure.
  • Clutch pedal travel.
  • Air in the hydraulic system.
  • Release-bearing movement.
  • Clutch-disc distortion.
  • Selector-cable adjustment.

If only reverse is affected, the reverse lockout, linkage travel, or internal reverse components become more suspicious.

Why the Problem May Be Worse When the Engine Is Hot

Some faults become more noticeable after driving.

Heat can alter the behaviour of hydraulic seals, clutch components, cables, and gearbox oil. A slave cylinder may lose pressure when hot, or a distorted clutch disc may drag more once temperatures rise.

We may observe:

  • Reverse works when cold but fails after a journey.
  • The clutch pedal becomes softer in traffic.
  • Pumping the pedal restores operation temporarily.
  • Gear selection becomes harder after repeated stop-and-start driving.

A heat-related pattern is useful diagnostic information. We should tell the mechanic whether the problem occurs from cold, after warming up, or under both conditions.

Why the Problem May Be Worse When Cold

If reverse is difficult only during the first few minutes, thick transmission fluid or marginal clutch release may be involved.

A healthy gearbox can still feel slightly firmer on a cold morning, but it should not require excessive force or produce repeated grinding.

Cold-related symptoms may point to:

  • Old or incorrect gearbox oil.
  • A clutch that only just releases far enough.
  • Stiff selector cables.
  • Worn linkage joints.
  • Moisture or corrosion in moving components.

The pattern matters more than a single difficult shift.

Safe Troubleshooting Sequence

We can follow a logical process without dismantling the car.

Step 1: Check Pedal Travel

Remove any obstruction around the clutch pedal. Press it several times and note whether it feels smooth, firm, and consistent.

Step 2: Try Reverse With the Engine Off

If it enters easily with the engine off, clutch drag or hydraulic trouble becomes more likely.

Step 3: Start the Engine and Wait

Press the clutch fully, wait three seconds, and try reverse without forcing it.

Step 4: Select First Before Reverse

Select first, return to neutral, and then attempt reverse.

Step 5: Pump the Clutch Pedal

Press the pedal several times. If gear selection improves, the hydraulic system may be losing pressure or containing air.

Step 6: Check Other Gears

Determine whether first, second, or other gears are also difficult.

Step 7: Note Sounds and Sensations

Listen for grinding, clicking, rattling, or knocking. Pay attention to whether the gear lever feels blocked, loose, or normal.

Step 8: Check for Leaks

Look for fluid beneath the vehicle and inspect accessible fluid reservoirs without opening hot or pressurised systems.

Step 9: Arrange Professional Diagnosis

If the fault persists, stop forcing the lever and have the clutch, linkage, hydraulics, and gearbox inspected.

What Not to Do When Reverse Will Not Engage

Frustration can tempt us to use force, but forcing reverse can damage selector forks, cables, bushes, and gear teeth.

Avoid:

  • Slamming the lever into reverse.
  • Revving the engine while trying to engage the gear.
  • Repeatedly crunching the gearbox.
  • Holding the lever in place when it jumps out.
  • Driving with a known hydraulic-fluid leak.
  • Continuing to drive if several gears are failing.
  • Using an unsuitable gearbox additive as a substitute for diagnosis.
  • Adjusting selector cables without the proper procedure.

A gear lever is not a crowbar. If it refuses to move, something is preventing correct engagement.

Can We Continue Driving the Vauxhall Adam?

Whether the car remains safe to drive depends on the symptoms.

If reverse occasionally resists but engages smoothly after selecting first, we may be able to drive cautiously to a workshop. However, the fault should still be investigated if it becomes frequent.

We should avoid driving when:

  • Reverse produces severe grinding.
  • The clutch pedal loses pressure.
  • The fluid level is low.
  • First and reverse are becoming impossible to select.
  • Gears jump out.
  • The gearbox makes loud mechanical noises.
  • The vehicle creeps with the clutch fully pressed.
  • Gear selection is deteriorating rapidly.
  • There is a visible leak.

A clutch or gearbox fault can worsen without much warning. Losing the ability to select gears in traffic is far more inconvenient—and more dangerous—than arranging an inspection early.

How a Mechanic Will Diagnose the Fault

A competent technician should not immediately recommend a gearbox replacement. Diagnosis normally begins with the external systems.

The mechanic may:

  1. Test the car from cold and at operating temperature.
  2. Check clutch pedal feel and travel.
  3. Inspect hydraulic-fluid level and condition.
  4. Look for leaks at the master and slave cylinders.
  5. Confirm whether the clutch releases fully.
  6. Inspect selector cables, bushes, and mountings.
  7. Check gear-lever and reverse-lockout operation.
  8. Verify gearbox-oil level and specification.
  9. Adjust the selector mechanism where applicable.
  10. Inspect or remove the gearbox if internal damage is suspected.

The order matters. There is little sense dismantling a transmission before checking whether a cable has slipped out of adjustment.

Possible Repairs

The repair depends entirely on the diagnosis.

Clutch Hydraulic Repair

This may involve bleeding the system, replacing a leaking master cylinder, repairing a pipe, or replacing the slave cylinder.

Some slave-cylinder designs are located inside the gearbox bellhousing. In that case, gearbox removal may be required even though the gearbox itself is healthy.

Selector Cable Adjustment or Replacement

If the cable is stretched, detached, seized, or incorrectly adjusted, it may need resetting or replacement.

Worn clips and bushes should also be renewed.

Gear-Lever Mechanism Repair

A damaged reverse-lockout collar, guide, spring, or lever housing may be repaired without opening the gearbox.

Clutch Replacement

A worn or distorted clutch may require a complete clutch kit. Replacing the friction disc alone is rarely the best approach because the pressure plate and release bearing have experienced similar use.

The flywheel should also be inspected.

Gearbox Repair or Replacement

If reverse-gear components are internally damaged, the transmission may need rebuilding or replacing.

The best option depends on:

  • The extent of the damage.
  • Availability of parts.
  • Labour costs.
  • Vehicle condition.
  • Mileage.
  • Warranty offered.
  • Price and history of a used gearbox.
  • Cost of a professionally reconditioned unit.

A cheap used gearbox can look attractive, but its internal condition may be unknown. A reconditioned gearbox with a meaningful warranty may offer better long-term value.

How to Explain the Fault Clearly to a Garage

A precise description can save diagnostic time.

Instead of saying only, “Reverse does not work,” tell the garage:

  • Whether the engine was hot or cold.
  • Whether reverse works with the engine switched off.
  • Whether first gear is also difficult.
  • Whether the gearbox grinds.
  • Whether pumping the clutch helps.
  • Whether the clutch pedal feels different.
  • Whether the fault appeared suddenly or gradually.
  • Whether recent clutch, gearbox, or engine work was completed.
  • Whether the reverse lights activate.
  • Whether the gear jumps out or simply refuses to enter.

These clues can steer the technician toward the correct system.

Preventing Future Reverse-Gear Problems

Not every failure can be prevented, but careful driving and maintenance reduce unnecessary stress.

Pause Before Selecting Reverse

Stop fully, press the clutch to the floor, and wait briefly. This allows rotating gearbox parts to slow.

Do Not Rest a Hand on the Gear Lever

Keeping constant pressure on the lever can load selector components unnecessarily.

Avoid Holding the Car on the Clutch

Use the brake or handbrake on hills. Balancing the car using the clutch creates heat and accelerates wear.

Secure the Floor Mats

Make sure the clutch pedal can complete its full travel.

Investigate Fluid Loss Early

A low hydraulic-fluid level is a warning, not a maintenance routine.

Use the Correct Gearbox Oil

Only use a fluid that matches the transmission specification.

Respond to Early Changes

A slightly vague lever, altered pedal feel, or occasional crunch is the car whispering before it begins to shout. Early repairs are often simpler and less expensive.

Is a Reverse-Gear Problem Always Expensive?

No. The cost can vary enormously.

At the lower end, the issue may involve a floor mat, selector adjustment, worn clip, or minor hydraulic bleeding. In the middle, we may be dealing with a master cylinder, selector cable, or clutch replacement.

At the upper end, internal gearbox damage or a slave cylinder located inside the bellhousing can create substantial labour costs.

The symptom alone does not reveal the bill. Diagnosis does.

That is why we should be cautious of anyone who declares the gearbox “finished” without inspecting the clutch operation and selector system.

Final Thoughts

When a Vauxhall Adam won’t go into reverse, the gearbox itself is only one of several possible suspects.

The clutch may not be disengaging fully. The hydraulic system may be losing pressure. A selector cable may have stretched, a linkage bush may have worn, or the reverse lockout may be obstructed. Cold or incorrect gearbox oil can also make selection harder, while internal transmission damage remains possible in more serious cases.

Our most useful initial test is simple: compare reverse selection with the engine running and switched off. If reverse works normally with the engine off, clutch drag deserves close attention. If the lever remains blocked in both conditions, the linkage, lockout, or internal selector components may be responsible.

We should never force the gear lever or repeatedly grind reverse. Metal parts rarely respond well to persuasion. A small issue can grow teeth when we keep pushing it.

By observing the symptoms, checking the clutch pedal, trying a careful selection sequence, and arranging a proper mechanical inspection, we can identify the real cause without replacing expensive parts unnecessarily.

Frequently Asked Questions

1. Why does my Vauxhall Adam go into reverse when the engine is off?

If reverse engages with the engine off but not while it is running, the clutch may not be disengaging fully. The gearbox input shaft may continue spinning even with the clutch pedal depressed. Possible causes include air in the hydraulic system, a leaking cylinder, insufficient pedal travel, or a worn clutch assembly.

2. Why does reverse crunch in my Vauxhall Adam?

Crunching usually means the gearbox components are still rotating when reverse is selected. This can happen if the vehicle has not stopped completely, reverse is selected too quickly, or the clutch is dragging. Persistent crunching should be investigated because repeated grinding can damage the reverse-gear teeth.

3. Can low gearbox oil stop reverse from working?

Low gearbox oil can contribute to poor shifting, noise, overheating, and internal wear. However, a reverse-only problem is more commonly related to clutch release, selector adjustment, or reverse components. The oil level and specification should still be checked if there are leaks, noises, or stiffness in several gears.

4. Why do I have to select first gear before reverse?

Selecting first can stop or reposition the rotating gearbox shafts, allowing the reverse-gear teeth to align. Doing this occasionally can be normal, but needing the technique every time may indicate clutch drag, linkage wear, or a selector problem.

5. Should I replace the gearbox if reverse will not engage?

Not without a proper diagnosis. A mechanic should inspect the clutch hydraulics, pedal travel, selector cables, linkage, lockout mechanism, and gearbox oil before condemning the transmission. Many reverse-selection problems originate outside the gearbox and can be repaired without replacing it.
