Transmission Range Switch: Description and Operation
TRANSMISSION RANGE SWITCH, GEAR ENGAGED
The Transmission Range (TR) switch is fitted on the transmission housing. It contains the reversing light switch, starting interlock contact and
switches which inform the Transmission Control Module (TCM) about which range (gear) the transmission is operating in.
In principle, the TR switch is a position switch which is powered via +X and in which a number of slip contacts indicate the position. The
combination of terminals A, B, C and D gives the selector lever position (see table above). The slip contacts can be either closed (=ON) or open
(=OFF).
