Transmission Control Module (TCM)






Transmission control module (TCM)





The transmission control module (1) receives the following information from the engine control module (ECM) (2):
- engine air mass and speed from the mass air flow (MAF) sensor (3)
- throttle angle from the throttle position (TP) sensor (4).
The transmission control module (TCM) uses this information to calculate gear shifting.
