Automatic Gearbox Repairs & Rebuilds

Modern automatic transmissions are sophisticated systems that require specialist knowledge and equipment. Our technicians are experienced in diagnosing and repairing a wide range of automatic gearbox faults, from minor electrical issues to complete gearbox rebuilds.

We regularly work on:

  • ZF automatic gearboxes

  • DSG gearboxes

  • CVT transmissions

  • Multitronic gearboxes

  • Powershift transmissions

  • Torque converter automatic gearboxes

As members of the ZF ProTech network, our technicians have received specialist training on ZF transmission systems found in many BMW, Jaguar, Land Rover and Range Rover vehicles.

Common Automatic Gearbox Problems

  • Delayed gear changes

  • Gearbox slipping

  • Transmission warning lights

  • Harsh or jerky shifting

  • Limp mode activation

  • Torque converter faults

  • Mechatronic unit failures

  • A faulty manual gearbox can quickly affect vehicle performance and drivability. Our workshop is equipped to diagnose and repair all types of manual transmission faults, helping customers avoid unnecessary replacement costs.

    Our manual gearbox services include:

    • Gearbox rebuilds

    • Bearing replacement

    • Synchromesh repairs

    • Differential repairs

    • Gear replacement

    • Clutch and flywheel replacement

    Whether your vehicle is struggling to select gears, making unusual noises or experiencing complete gearbox failure, we can provide a reliable repair solution.

  • Semi-automatic gearboxes require specialist expertise that many general garages simply do not possess.

    We are recognised for our extensive experience repairing and rebuilding semi-automatic systems fitted to vehicles from manufacturers including:

    • Renault

    • Vauxhall

    • Citroën

    • Peugeot

    • Fiat

    • Volkswagen Group

    Our technicians regularly repair actuator units, control modules and gearbox components that other repairers often recommend replacing entirely.

  • We were among the first transmission specialists in the UK to offer in-house repair and rebuild services for Ford Powershift transmissions.

    Rather than replacing complete gearbox assemblies, we can often repair or replace individual components, including:

    • Clutch packs

    • Mechatronic units

    • Transmission control modules

    • Internal gearbox components

    This approach can save customers thousands of pounds compared with full gearbox replacement.

    We regularly work on:

    • Ford Focus

    • Ford Kuga

    • Ford Galaxy

    • Ford S-Max

    • Ford C-Max

  • Our team has extensive experience repairing and rebuilding Audi Multitronic and CVT transmissions, as well as CVT systems found in other manufacturers.

    Common faults include:

    • Juddering during acceleration

    • Gear selection issues

    • Transmission warning lights

    • Loss of drive

    • Electronic control unit faults

    Our diagnostic process identifies the root cause of the problem, allowing us to provide the most cost-effective repair solution.

  • Correct diagnosis is the key to successful gearbox repairs.

    Using dealer-level diagnostic equipment and specialist transmission testing procedures, we can accurately identify faults affecting:

    • Automatic transmissions

    • Manual gearboxes

    • Semi-automatic systems

    • Mechatronic units

    • Control modules

    • Differentials

    Many gearbox issues can be repaired without replacing the entire transmission, saving customers significant expense.
