Transmission Control Systems: Locations

The transmission control system has four unique connectors, one for transmission control module (TCM) and three on the transmission itself (B, C and D). Apart from that the transmission control system wiring is incorporated with the other cable harnesses in the car (mainly on its left-hand side).





There are three connectors (B, C and D) are on the front left of the transmission to connect it with the control system.

Illustrations show terminals on cable harness connectors. Transmission connectors are numbered in opposite order.
