The PCM is short for powertrain control module. It monitors the engine and transmission and makes everything work together. For example, the PCM will check the vehicle speed, RPM, throttle position and tell the transmission when to do a 2-3 upshift or downshift when necessary. It also logs trouble codes if there's a problem.
