The KM176 (also known as the F4A21) was a four speed electronic automatic transaxle used in the fifth generation Mitsubishi Lancer.
The torque converter includes a damper clutch which causes the converter to lock at low vehicle speeds. The operation of the clutch is controlled by the Transaxle Control Unit.
Gear selection is electronic and is controlled by solenoids which are activated by the Transaxle Control Unit. The TCU uses information from sensors which provide information on vehicle speed, throttle position, engine coolant temperature, gear lever position, engine speed, overdrive switch and kickdown drum speed.
