Transmission Position Switch/Sensor: Description and Operation
Sensor, Transmission Range (TRS)
Note:
This article has been modified by technical service bulletin 211495 Dated Sep. 1, 1995.
During the week of June 5, 1995, a running change was made to St. Louis built vehicles equipped with 41TE transaxles that incorporated a Transaxle
Range Sensor (TRS).
Description
The Transmission Range Sensor (TRS) is located internal to the transaxle. This sensor provides the Transmission Control Module (TCM) with
information on the shift lever position, contains the transmission temperature sensor, and contains the switch for the back-up lamps.
Operation
Circuit T1 provides an input to the TCM when the shift lever is in the NEUTRAL/OVERDRIVE or LOW position.
Circuit T3 provides an input to the TCM when the shift lever is in the PARK, 3 or LOW positions.
Circuit T42 provides an input to the TCM when the shift lever is in the PARK, REVERSE, NEUTRAL, or LOW position.
Circuit T41 provides an input to the TCM when the shift lever is in PARK, or NEUTRAL position. This circuit is also the ground circuit for the coil
side of the engine starter motor relay.
Circuit T54 provides the transmission temperature sensor signal as an input to the TCM.
Circuit T13 is ground for the transmission temperature sensor.
The TRS is case grounded to the transaxle.
Power for the back-up lamp portion of the TRS is supplied by circuit A22. This circuit is HOT in the RUN position only, and protected by a 10 amp
fuse located in cavity 8 of the junction block.
When the operator places the vehicle in REVERSE, circuits A22 and L1 are connected. The L1 circuit is connected to the back-up lamps, and the
All-Wheel Drive (AWD) solenoids, if equipped (these solenoids are used to disconnect the AWD system when in REVERSE).
