by Michael Ryan

Operation

A shiftable automatic transmission is mechanically an automatic transmission with an electronic override system that allows for driver shift control.

Function

Shiftable automatic transmissions do not have a clutch in the sense of a manual transmission. Instead they use a torque converter to transfer engine power into forward motion through the wheels.

Types

Expert Insight
