Controller Area Network (CAN) Interface
WARNING: This page is about a different car, the 2007 Ford Expedition EL and 2007 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.
For the TCM to carry out shift point and shift quality management, a number of external signals are required. For shift point management alone, the TCM requires output speed sensor, throttle pedal position, brake pedal status, gear selection position, transmission fluid temperature, 4WD position, traction control, engine speed and engine torque. The controller area network (CAN) bus is used to share information between control modules.
