Automatic Transmission Output Speed Sensor
WARNING: This page is about a different variant/trim than selected.
The output speed sensor assembly is a two wire hall-effect type sensor. The sensor is mounted on the interior of the transmission case. The TCM supplies a 9 V reference circuit and signal circuit to the output speed sensor. As the rotational speed of the output carrier assembly increases, the frequency of the output speed sensor signal increases. The reluctor ring is part of the Park gear assembly, which is splined to the transmission output shaft. The TCM used the output speed sensor signal along with the input and intermediate speed sensor signals to determine transmission line pressure, shift patterns, correct gear ratio and the torque converter clutch slip speed.
