Theory Of Operation

WARNING: This page is about a different car, the 2014 Dodge Journey. However, it is still accessible from the selected car via links, so may be relevant.

The transmission control system uses three speed sensors, one to measure input RPM, one to measure Transfer Speed output RPM of the main transmission assembly, and a third to measure the final transmission output RPM. These inputs are essential for proper transmission operation. Therefore, the integrity of this data is verified through system checks.
