The TCM inside the trans controls transmission functions.As tacamo01 mentioned, the BCM (Body Control Module) controls most of the car's "features", allowing enabling or disabling features (options). For example, on my '15 Rallye, I used AlfaOBD to enable several "features" in my BCM, such as Performance Pages, leaving fog lights on with high beams, and opening the front windows via the key fob.
