A transmission computer controls the changing of gears in an automatic transmission motor. Transmission computers are most commonly found in automobiles, where they act as the core component of the transmission control module.
The transmission computer is an example of one of many feedback systems found in today's vehicles. A feedback system tracks the status of a piece of equipment and then adjusts the equipment's operation as necessary. Modern transmission computers use a number of sensors to track engine variables, including rotations per minute and acceleration. The transmission computer utilizes this information to decide whether or not to shift gears.
