Where is the Transmission Computer (TCM/TCU) located?
The TCM or TCU is usually mounted inside the engine bay, near or on the transmission housing, though its location varies by make and model. In some vehicles it may be found under the hood attached to the firewall, beneath the battery tray, or integrated into the valve body inside the transmission itself. Always check your service manual or contact us with your VIN for precise location details.
