The AW F21 is a 6-speed electronically controlled automatic transmission manufactured by Aisin AW in Japan. This transmission features the latest technology in automatic transmissions for transverse all-wheel drive (AWD) units. This transmission features lock-up slip control, 'CommandShift™' functions, automatic and driver-selectable modes for optimum performance on and off-road.

The transmission is controlled by the TCM module, which contains software that controls the operation of the semi-automatic "CommandShift™" mode. The TCM allows the transmission to be operated as a conventional automatic transmission by moving the selector lever to the P, R, N or D positions. Moving the selector across the gate to the "M/S" position puts the transmission in the electronic "Sport" mode. Further movement of the lever in the longitudinal direction, to the + or - position, puts the transmission in the electronic mechanical "CommandShift™" mode.
