If you’re looking to enhance the performance of your vehicle equipped with an automatic transmission, gearbox TCU tuning is the perfect complement to our engine ECU remapping.

Remapping your gearbox can be done independently, but it is typically performed alongside an engine remap. This combination enhances both performance and the overall driving experience of your car, van, or motorhome.

The standard gearbox map frequently limits the performance of many vehicles, particularly when the engine is remapped. Therefore, tuning and recalibrating your gearbox may be necessary to eliminate torque limits in the gearbox’s TCU. This adjustment enables you to fully utilise the extra torque generated by your remapped engine.

So, to get the best performance from your vehicle with an auto box, we’d suggest tuning both the ECU & TCU control units to match each other, and we offer a package (at a reduced cost) if you have both remaps carried out together.

Gearbox Remapping
  • Increasing the TCU torque limiters ensures the transmission cannot limit the performance of the engine.
  • Increasing the hydraulic pressure can increase clutch clamping pressure to prevent clutch slip on highly tuned vehicles.
  • Changing the rpm limiter of the engine is often not possible without modifying the TCU software.

I have used this service on my Land Rover Range Rover Sport. I’m so pleased with it, everything was super quick and to a high standard. Very trustworthy and polite. I would highly recommend! I’ve already referred all my friends and family.

Remapped my wife’s 2017 Mercedes C Class Coupe. The car is much more responsive and power delivery is much smoother. The guys at X One Tuning were really knowledgeable and helpful. Will definitely use them again in the future.
