TCU (Transmission) Tuning
Faster shifts, increased torque limits, and optimized shift points for your automatic or DSG gearbox.
Overview
A TCU tune is the perfect companion to an ECU tune. By recalibrating the transmission control unit, we can increase the clamping pressure of the clutches, raise torque limiters, and drastically reduce shift times. This ensures your gearbox can safely handle increased engine power while providing a more engaging driving experience.
Factory transmission software is often programmed for comfort and emissions, resulting in sluggish shifts and premature upshifting. Our custom TCU calibrations transform the behavior of your gearbox, offering lightning-fast shifts in sport mode while maintaining smooth, comfortable gear changes during normal daily driving.

Frequently Asked Questions
Q: Is a TCU tune necessary if I get an ECU tune?
A:While not always strictly necessary for a Stage 1 ECU tune, a TCU tune is highly recommended to remove torque limiters and ensure the transmission can safely handle the increased power.
Q: Will it make my daily driving uncomfortable?
A:No, our TCU tunes are designed to retain smooth shifting characteristics in 'Drive' or 'Comfort' modes, while saving the aggressive, rapid shifts for 'Sport' or 'Manual' modes.
