    In order for modern cars to have smooth gear changes at the right times, the Automatic Transmissions are fully electronically and computer controlled. The device that controls them is called the Automatic Transmission Electronic Control Unit (Automatic Transmission ECU) sometimes called an Automatic Transmission Computer.

    The Automatic Transmission computer monitors a wide range of electronic sensors and actuators such as:

    • Automatic Transmission Computer
    • Torque Cover
    • Bands
    • Oil Pump
    • Clutch Packs
    • Automatic Transmission Fluid
    • Hydraulic System
    • Planetary Gear Sets
    • Governor and the Modulator
    • Seals and Gaskets
    • Valve Body
    • Throttle Cable
    • Electrical Solenoids
    • Throttle Position
    • Speed Sensor
    • Electronic Temperature Sensor

     

    If any one of these automatic transmission components is faulty then the automatic transmission computer self diagnostic system while log a fault code into memory, and turn the automatic transmission light on the dash.
