Transmission Control Unit

Today’s electronically-controlled overdrive transmissions can offer excellent fuel economy and performance, but factory transmission controllers often fall short of the mark when it comes to street/strip or 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.

Click here to see details of our software.

The TCI® Transmission Control Unit is fully-programmable, and can be 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. The TCI® Transmission Control Unit will work with most GM, and Ford electronically-controlled automatic transmissions*, and 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***.

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 TCI® Transmission Control Unit includes 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 allows the TCI® Transmission Control Unit 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.
