TCM
TCM (Transmission Control Module) is a critical computer component in modern vehicles that manages how the automatic transmission works. Think of it as the "brain" that decides when and how to change gears in a car. When someone mentions TCM in their automotive resume, they're referring to their experience with diagnosing, repairing, or replacing these electronic control units. This is an important skill as modern vehicles rely heavily on these computer systems for smooth operation.
