Transmission repairs based on inspection

Diagnosis can include scan data, road testing and inspecting the transmission fluid and pan for signs of wear or damage.
This helps determine whether the vehicle needs servicing, a targeted repair or a full rebuild, rather than replacing parts unnecessarily.

For broader vehicle fault finding, see Vehicle Servicing & Repairs.

Complete automatic transmission rebuilds

Automatic transmissions are stripped, cleaned, inspected and rebuilt in the workshop using specialist equipment and processes.
Every complete rebuild includes a rebuilt torque converter and is tested before handover. Full rebuilds carry a 12-month warranty.

CVT, DSG and modern automatic transmissions

CVT, DSG, dual-clutch and conventional automatic transmissions each have different common faults and repair requirements.
Shifting Gears Automotive has specialist diagnostic and coding equipment to help identify and repair these systems properly.

Transmission servicing without flush machines

Shifting Gears Automotive does not use transmission flush machines.
Transmission servicing is carried out by draining and inspecting the fluid, replacing the filter and gasket where accessible, and refilling with the correct transmission fluid.
For performance applications, see Performance Transmission & Drive Train Upgrades.

Scan data, road testing and pan inspection may be used to establish whether the problem can be serviced or repaired, or whether internal damage means a rebuild is the better option.

Yes. Every complete rebuild includes a rebuilt torque converter because the converter and transmission share the same oil. Reusing a contaminated or worn converter could damage the rebuilt transmission.

No. Shifting Gears Automotive drains and inspects the transmission fluid instead. Where accessible, the pan is removed and the filter and gasket are replaced before the correct fluid is refilled.

Yes. CVT, DSG and dual-clutch systems are assessed according to the specific transmission type, as their common faults and repair requirements differ.
