What does gearbox tuning change?
A transmission control unit manages shift points, clutch pressure, torque limits and the way the gearbox responds to the accelerator. A careful TCU calibration can improve these settings for a more responsive and consistent drive.
Potential benefits
Depending on the vehicle and gearbox, tuning may deliver quicker shifts, improved manual-mode response, better use of the engine's torque and smoother everyday changes. Results depend on the transmission, software version and mechanical condition.
- More responsive upshifts and downshifts
- Revised shift points for stronger drivability
- Improved torque management where supported
- Better control in sport or manual modes
Safety and compatibility
We check the vehicle and gearbox first, and we do not tune a transmission with warning lights, slipping or known mechanical faults. Send your registration and gearbox details so we can confirm compatibility and give honest advice.
Frequently Asked Questions
No. An ECU remap changes engine software, while gearbox tuning changes the transmission control unit. They can be carried out separately or calibrated to work together where appropriate.
