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:
- Designed to be maintenance free
- Transmission fluid is fill for life
- The torque converter features a controlled slip feature with
electronically regulated lock-up control on gears 2 to 6
- Shift programs controlled by the TCM
- TCM has an adaptive capability to ensure efficient gear shift quality
throughout the service life of the transmission
- Diagnostics available from the TCM and the GSM via the high speed CAN
(controller area network) bus.
