Overview

OVERVIEW

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

The transmission is controlled by a TCM (transmission control module) which contains software to provide operation as a semi-automatic 'CommandShift' transmission and a Gear Shift Module (GSM). The GSM is a rotary actuator which converts driver selections for P, R, N, D and S on the rotary TCS (transmission control switch) into rotary movement of the transmission selector shaft allowing the system to operate as a 'shift by wire' system, with no mechanical link to the transmission for drive selections.

The TCM allows the transmission to be operated as a conventional automatic unit by selecting P, R, N, D, S on the TCS.

Rotation of the TCS to the 'S' position puts the transmission into electronic 'Sport' mode. Operation of the steering wheel mounted + or - paddle switches puts the transmission into electronic manual 'CommandShift' mode.

Refer to: External Controls (307-05 Automatic Transmission/Transaxle External Controls - Vehicles With: AWF21 6-Speed Automatic Transmission, Description and Operation).

The transmission system uses an auxiliary battery module which powers a failsafe system to allow the engagement of 'Park' in the event of vehicle power failure.

The AW F21 transmission has the following features:
