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 retro-fit use, let alone all-out racing applications. The revolutionary Transmission Controller by FAST™ overcomes the shortcomings of performance-compromised OEM electronic transmission controllers and elevates electronically controlled automatic transmissions to a higher standard of performance and tunability.

Engineered to work with nearly any electronically controlled automatic transmission, the FAST™ Transmission Controller is fully-programmable and can be run either as a standalone unit – even with a non-computer controlled engine – or in conjunction with either OEM or aftermarket ECUs, such as the FAST™ XFI™ Fuel Injection System and carbureted applications. The FAST™ Transmission Controller will work with most GM, Ford, and Chrysler 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 via a simple serial port interface with any Windows-based PC or laptop. Its ability to communicate with any ECU that supports CAN 2.0b devices means that the FAST™ Transmission Controller uses a simpler, easier-to-install wiring harness than most other aftermarket transmission controllers. The FAST™ Transmission Controller 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.
