Circuit Description

WARNING: This page is about a different car, the 2003 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

The transmission control module (TCM) calculates gear ratio based on data from the transmission input shaft speed (ISS) and output shaft speed (OSS) sensors. The TCM compares the calculated gear ratio to the known gear ratio for each commanded gear.

If the TCM detects an incorrect 5th gear ratio, indicating excessive slip or drag within the transmission, then DTC P0735 sets. DTC P0735 is a type A DTC.
