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.
