Optimise Performance And Drivability


Vehicles equipped with an automatic transmission are normally fitted with a TCU (Transmission Control Unit). The TCU controls all aspects of the transmission’s functionality (gear shift, torque limitation etc). The TCU works together with the Engine Control Unit by sending and receiving real time data across the vehicles can-bus data network system. When tuning a vehicle, it is often recommend to have the ECU and TCU remapped simultaneously, this will ensure both control units continue to work in harmony together and will help to fully optimize the performance and driveability of the vehicle.

Benefits of Our Transmission Tuning Software

Shift Speeds:

Increasing the speed in which the gearbox changes gear.


Torque Limiters:

Increasing the transmission torque limiters will ensure the transmission cannot limit the performance of the engine.

Hydraulic Pressure:

Increasing the hydraulic pressure can increase clutch clamping pressure to prevent clutch slip on highly tuned vehicles avoiding clutch slip prolonging the life of the gearbox.

Shift Points:

Changing the rpm limiters of the engine is often not possible without modifying the TCU software.
