The Most Trusted Gearbox Replacement

Replacing a gearbox is the right answer when the internal damage is too widespread to repair economically: damaged gear teeth, a cracked casing, or wear affecting several components at once. It is a substantial job and an expensive component, which is exactly why the diagnosis matters more here than anywhere else. Michanic confirms the gearbox is genuinely at fault at your home or office before any replacement is discussed.

Why Choose Our Gearbox Replacement Services?

  1. Confirmed Before Quoting:
    A slipping clutch, a failed hydraulic cylinder or a worn mounting can all mimic gearbox failure. Those are ruled out before anything this large is proposed.
  2. Reconditioned Considered:
    A reconditioned unit with a warranty is often better value than new, and sometimes the only realistic option on an older vehicle. We lay out the choices.
  3. Clutch Renewed With It:
    The gearbox is out anyway, so fitting a worn clutch back against a replacement gearbox makes no sense.
  4. Honest Assessment:
    On some vehicles the cost approaches the value of the car. If that is the case, you hear it plainly.

Why We are the Best Choice for Gearbox Replacement

  • Cause Established:
    Gearboxes fail for reasons, usually oil loss or a failing clutch. Fitting a replacement without addressing the cause risks the new unit.
  • Ancillaries Transferred Properly:
    Sensors, selector linkages and mountings are transferred and set up correctly, which is what makes the replacement drive as it should.
  • Filled With Correct Oil:
    The replacement is filled to level with the exact specification, since an incorrect fill is a common cause of early failure.
  • Fully Road Tested:
    Every gear is driven under load and on the overrun, with selection and noise checked before the vehicle is returned.

Because a gearbox is among the most expensive components on a car, the single most valuable part of this job is establishing that it has genuinely failed. A clutch that will not release makes every gear crunch and feels exactly like a broken gearbox. A collapsed engine mounting can cause a jumping out of gear that disappears once the mounting is replaced. Getting that diagnosis right is the difference between a modest repair and one that on an older vehicle can approach what the car is worth.

Frequently Asked Questions

  • How do I know the gearbox actually needs replacing?
    Loss of drive in a gear, stripped teeth, metal debris in the oil, or a cracked casing are conclusive. Difficulty selecting gears on its own is not, because a clutch that will not release produces the same symptom.
  • Is a reconditioned gearbox as good as new?
    A properly reconditioned unit from a reputable rebuilder, supplied with a warranty, is a sound choice and often far better value. On older vehicles it is frequently the only sensible option.
  • Should the clutch be replaced at the same time?
    Yes. The gearbox has to come out either way, and the labour is the bulk of the cost. Refitting a partly worn clutch against a replacement gearbox means paying for that access again before long.
  • What causes a gearbox to fail completely?
    Most often running low on oil through an unnoticed leak. Beyond that, a failing dual mass flywheel or slipping clutch putting shock loads through it, contaminated oil, or simply very high mileage.
  • Is it worth replacing the gearbox on an older car?
    Sometimes not, and we will say so. On a high mileage vehicle the cost can approach the value of the car, and you are entitled to that assessment before committing rather than after.
