Gearbox TCU Remapping – Croydon

At MCA Performance, we specialise in professional TCU remapping for automatic vehicles.

What is the TCU?

The Transmission Control Unit (TCU) plays a crucial role in managing your automatic vehicle’s transmission, from gear shifts to torque control. It controls when it shifts and how smoothly or aggressively it shifts. It also chooses which gear you’re in, based on your driving, the load of the vehicle, and what mode your vehicle is in, e.g. sport mode or eco mode.

Working in conjunction with the Engine Control Unit (ECU), the TCU constantly exchanges data to optimise your vehicle’s overall performance.

How does TCU Remapping at MCA Performance work?

When tuning a vehicle, we often recommend remapping both the ECU and TCU at the same time. This approach ensures the two systems work seamlessly together, allowing for enhanced performance and smoother driving. Key adjustments include optimising shift speeds for faster, more responsive gear changes, and increasing torque limits to prevent the transmission from restricting engine power. Additionally, boosting hydraulic pressure strengthens clutch clamping force, preventing clutch slip, especially in highly tuned vehicles. By adjusting shift points, we can fine-tune the engine’s rpm limiter, improving power delivery and overall driving dynamics.

By remapping both the ECU and TCU, we help unlock your vehicle’s full potential, providing a more responsive and enjoyable driving experience. Our expert technicians ensure that both control units are carefully calibrated to work together efficiently, delivering significant improvements in power, throttle response, and driving pleasure.

If you’re looking for more power and sound from your vehicle, come to MCA Performance. We only work on remaps and exhausts, because that’s what we do best.
