Transmission Control System Relay: Description and Operation

OPERATION

This vehicle is not equipped with a transmission relay. The transmission control is done through the TIPM. The TIPM receives an input signal from the PCM. Once the TIPM receives the signal, it will output a 12 volt supply to the transmission.
