Transmission Control Module (TCM)
WARNING: This page is about a different car, the 2006 Mercury Montego, 2006 Ford Freestyle, and 2006 Ford Five Hundred. However, it is still accessible from the selected car via links, so may be relevant.
The transmission control module controls (TCM) transaxle function. It is the transaxle-to-vehicle-system interface. Also supplies the signal to the powertrain control module (PCM) for starter interlock. Diagnostic trouble codes that are transaxle-related are supplied to the PCM, ABS and all wheel drive (AWD) modules from the TCM. The transmission fluid temperature sensor is built into the TCM.
TCM monitored inputs from other electronic modules:
- Electronic control module (ECM)
- throttle position sensor
- engine torque
- engine speed
- ABS module
- vehicle speed
- wheel speed
- active states
- Traction control module (AWD)
- vehicle speed
- wheel speed
- active states
- Anti-lock brake system
