Today's electronically-controlled overdrive transmissions can offer excellent fuel economy and performance, but factory transmission controllers often fall short when it comes to street/strip and retrofit use, let alone all-out racing applications. The revolutionary new TCI® Transmission Control Unit elevates electronically controlled automatic transmissions to a new standard of performance and tunability.

The Transmission Controller is fully-programmable and can run as a standalone unit - even with a non-computer controlled engine - or in conjunction with OEM or aftermarket engine computers such as the FAST™ XFI™ system. It includes a wide array of tuning options including load, gear, RPM and speed-based programming - all of which can be adjusted by simply connecting the unit to any Windows based pc or laptop.

The TCU will work with most GM and Ford electronically-controlled automatic transmissions. Its ability to communicate with the FAST™ XFI™ fuel injection system and other compatible CAN 2.0b devices means that the TCI® Transmission Control Unit uses a simpler, easier to install wiring harness than most other aftermarket transmission controllers. The TCU comes with easy-to-use T-Com™ software, which allows simple plug and play transmission operation via several built-in programs, as well as custom tuning and programming, data logging and fault diagnosis. A multitude of digital inputs and outputs, analog inputs, and speed inputs and outputs allow the Transmission Controller to be custom tweaked to fit any requirement, such as steering wheel-based button shifting in a drag race application, or manifold pressure-based shift firmness in a turbocharged application.
