Circuit Description

WARNING: This page is about a different variant/trim than selected.

The TCM calculates gear ratio based on data from the automatic transmission input shaft speed and output shaft speed sensors. The TCM compares the known transmission gear ratio to a calculated ratio for each commanded gear.

If the TCM detects an incorrect 2nd gear ratio, indicating excessive slip or drag within the transmission, then DTC P0732 sets. DTC P0732 is a type C DTC.
