Transmission Control System Relay: Description and Operation

DESCRIPTION

This relay is operated by the A-604 controller. Its purpose is to make operating voltage available to the solenoids and switches located in the Solenoid Pack. When the Controller opens the relay, voltage is taken away from the solenoids and the transmission goes into a limp-in mode. While in this mode, only second gear, reverse and neutral are available.

This relay may also be referred to as the Safety Shutdown Relay.
