Where is the transmission control unit located on a 2002 Dodge Intrepid?

The Transmission Control Unit (TCM) on a 2002 Dodge Intrepid is typically located within the transmission itself. It's not a separate, easily accessible box like some other vehicle systems. You won't find it under the dash or in the engine bay. To access it, you would need to remove the transmission. This is a job best left to a professional mechanic.
