Category: Transmission Control

Here we will discuss codes related to the Transmission and the TCM (Transmission Control Module). Based on your vehicle you may have an Automatic Transmission or a CVT (Continuously Variable Transmission). A Transmission is the unit attached to the back of the engine, this is what helps the engine stay in its ideal RPM (revolutions per minute) range to increase fuel economy and optimize power output. When you move the shifter from park to drive you’re moving components inside the transmission which tells it you are ready to go and in what direction you want to go. In older cars or sport cars, instead of an automatic transmission there can be a manual transmission which requires more driver input to function and also has a third pedal in the floorboard called the clutch. The Automatic and CVT transmission has become a standard option in most vehicles these days.
