Theory Of Operation

WARNING: This page is about a different car, the 2009 Dodge Avenger and 2009 Chrysler Sebring. However, it is still accessible from the selected car via links, so may be relevant.

The Transmission Control Module (TCM) uses multiple sensors to calculate the gear ratio. If the ratio does not match a known ratio the DTC will set.
