APR's TCU Upgrade dramatically improves upon the transmission's function, drivability, and performance through a myriad of enhancement and custom features. Normal daily driving is smoother as we've improved upon the normal quirks and complaints associated with the driving experience. Sporty driving is far more capable with increased torque capacity, clamping pressure, torque management during shifts, AMAX in all gears, and optimized shift point! Both scenarios are optimized to deliver faster acceleration by matching the power output delivered by our ECU Upgrades. Lastly, the software loads to the factory TCU through the OBD-II port, resulting in a clean and headache-free install. Features: Faster up and down shifts in all modes Optimized shift points for faster acceleration and smoother driving Shift points for both stock and big turbo setups (B9 S4/S5/SQ5) at no additional charge Increased maximum allowable torque for higher output Increased clutch clamping pressure to hold more torque Optimized torque management during shifts for smoother and stronger shifts AMAX maximum acceleration shifting mode enabled on all gear shifts Manual mode auto 1-2 shift disabled Increased maximum RPM on big turbo software (B9 S4/S5/SQ5) Works perfectly with our ECU Upgrades Flash counter does not increase with each flash Direct OBDII port flash (No TCU removal) Free lifetime updates 30 day money back guarantee Maximum transmission torque capacity (Clutch pressure/current) To prevent clutch slip as much as physically possible on the factory clutches, we’ve increased the torque capacity of the transmission to its physical limits. Too much slip can cause excessive wear and damage the clutches. This can happen during gear shifts, transient response, and more, and is mostly on high powered vehicle setups with lots of grip. Clutch pressure is configured to be dynamic and will only increase as necessary. It does not run at the maximum allowable pressure and current at all time. Optimized wide open throttle shift points The factory wide open throttle shift points were designed to match the factory output of the vehicle. With tuning, they can be optimized future to improve acceleration times. For the best results our ECU and TCU upgrade must be used together. We have specific maps for the factory turbo, and our big turbo setups. Optimized shift strategies Depending on the vehicle mode, type of shift, braking vs accelerating, and more, the transmission will deliver different shifting strategies. We’ve smoothed part throttle / low torque situations for a comfortable normal drive while giving a more aggressive shift at full torque / high RPM for track driving purposes. Shift speeds are increased, and maximum acceleration modes (AMAX) are enabled in gears.

We have only validated our TCU upgrades while using our ECU upgrades. When not using both in combination, various behaviors and features may not be predictable or as described. Compatibility notes: Most 2023+ model year vehicles are not currently compatible due to a locked TCU.
