Transmission Controllers

Transmission Controllers & TCU Modules

Transmission controllers manage automatic transmission shift behavior through electronic solenoid control, allowing custom shift points, firmness, torque converter lockup strategy, and rev-matching. Standalone transmission controllers are essential for engine swaps, race builds, and vehicles with aftermarket ECUs that don't include integrated transmission control.

OneFastShop carries transmission controllers including standalone TCU modules, plug-and-play transmission controllers, shift firmness controllers, and transmission management systems for popular automatic transmissions.

Every transmission controller at OneFastShop ships brand-new with manufacturer warranty coverage. Whether you're controlling an automatic transmission in an engine swap, adding standalone shift management, or tuning shift behavior for the strip, OneFastShop has the controller.
