Transmission Speed Sensor: Description and Operation
TRANSMISSION COMPONENTS
Input And Output Speed Sensors (TISS) And (TOSS)
The two speed sensors are of the magnetic induction type, and are mounted on the left hand side of the transmission, the input sensor forward of the
transmission centre, and the output sensor close to the rear extension housing. The induced voltage in the input sensor is generated from machined
serrations on the forward clutch housing, and in the output speed sensor by serrations on the rear carrier assembly. The information from these two
sensors is used by the transmission control module (TCM) to determine whether the engine is running, vehicle speed, the gear ratio, the TCC slip, and
the turbine speed.
