Transmission Control Modules

A Transmission Control Module (TCM), also known as a Transmission Control Unit (TCU), is an electronic device that controls the automatic transmission in your vehicle. Sensors and data provided by the Engine Control Module calculate various components that identify how well your car or truck is performing. The TCM is responsible for functions including the optimal time to switch gears, monitoring fuel economy and emissions, and shift quality.

The age of your TCM plays a factor in how the unit functions. Modern day TCMs receive signals from several sources including engine sensors, automatic transmission sensors, and other controllers that determine how to run the transmission in the most efficient way. Older TCMs typically have dedicated inputs and sensors on the controlled engine components, whereas more modern units will gather information from a shared input.

The complexity of modern TCMs are unique to each make and model, and each calculation is based on a number of parameters — the end goal being to optimize the efficiency of your transmission.
