Transmission Control Modules

This web page is dedicated to the Transmission Control Modules that we have in our catalog here at Flagship One. We sell Transmission Control Modules for such car Brands as Ford, Dodge, GM, Jeep, Chrysler, Mazda, Cadillac, Lincoln, and much more.

"TCM" is an acronym that means "Transmission Control Module". A Transmission Control Module acts as a hub for information gathered by various sensors. The brake pedal sensor, turbine speed sensor, transmission fluid temperature sensor, and throttle position sensor all send data to the Transmission Control Module. The TCM reads this data and communicates with the transmission to determine accurate gear shifting to create a smooth driving experience. A properly functioning TCM creates optimal transmission performance and allows for better fuel economy, decreased emissions and better handling.

Poorly timed or hard shifting can signal a faulty Transmission Control Module. All Flagship One TCM units are refurbished to the original manufacturer's factory-fresh standards for the quality and peace of mind you deserve. Trust Flagship One for your replacement TCM and get savings and value, too!
