Navajo 2WD V6-4.0L OHV (1992)
Transmission Speed Sensor: Description and Operation
The Transmission Speed Sensor (TSS), located within the transaxle oil pan, produces an AC voltage that is proportional to the speed of the transaxle's
forward/reverse drum. Since this drum is mechanically connected to the torque converter, the sensor is also measuring turbine speed. The Electronic
Control Assembly (ECA) uses this input to determine upshift and downshift points.
