Nationwide mail-in postal service available with drop off at our Enfield office.
What is a TCM — Transmission Control Module?
The TCM — Transmission Control Module — also referred to as the TCU or gearbox ECU, is the dedicated electronic control unit responsible for managing all functions of an automatic or automated gearbox. It controls gear selection, shift timing, torque converter lockup, adaptation values and communication with other vehicle systems including the engine ECU and ABS module.
The TCM stores vehicle-specific adaptation data built up over time to match the gearbox's shift behaviour to the individual vehicle and driving style. Fitting a replacement TCM without cloning this data results in harsh, incorrect or erratic gear changes, limp mode activation, or in some cases the gearbox refusing to operate at all. Cloning transfers all of this data exactly onto the replacement unit, ensuring seamless operation from the moment of fitment.
Common TCM Fault Symptoms
- Gearbox in limp mode — vehicle limited to one or two gears
- Harsh or erratic gear changes
- Gearbox refusing to change gear under load
- Transmission warning light illuminated on dashboard
- Gearbox not adapting correctly — shifts feel wrong after battery replacement
- Complete loss of drive in some or all gears
- Communication fault codes between TCM and engine ECU
- Torque converter fault codes stored

Frequently Asked Questions
TCM — Transmission Control Module — and TCU — Transmission Control Unit — refer to the same component. Different manufacturers use different terminology but the function is identical. We clone both regardless of terminology.
The cloned TCM carries all existing adaptation data from the original unit so in most cases no adaptation reset is needed. Some vehicles may benefit from a short drive cycle to allow the gearbox to self-adapt. We will advise on the specific requirements for your vehicle.
Most TCM cloning jobs are completed within 3 to 5 working days of receiving your units. We will confirm an estimated turnaround when we acknowledge receipt.
