The other half of the drivetrain.
TCU / Gearbox Tuning
On modern automatics the gearbox computer can hold back a remapped engine: factory torque limiters, lazy shift maps and conservative clutch pressures. TCU calibration aligns the transmission with the engine so the whole drivetrain delivers together.
What you get
- Faster, crisper shifts
- Raised torque limiters on supported units
- Matched to your engine calibration
