How Many Variations of the AWF21?

There are many different variations (so we have over 60 different part numbers!). Each one for a different engine size (bellhousing) and varying electronic and solenoid systems for different years.

Only certain models will interchange with others, which is why we ask for your 17-digit VIN# when you order so we are 100% sure it is the matching unit for your vehicle!

The Aisin AWTF-80 series (AWF21) is a 6 speed automatic transmission designed for use in transverse engines. Its use of a 5-pinion planetary gearset and a Ravigneaux gearset makes it light and compact. This combination is known as a Lepelletier arrangement. The shifting of gears is managed by a computer program which oversees clutch-to-clutch actuation. Gear changes are accomplished by one clutch engaging the instant the clutch from the previous gear disengage.

The transmission control module (TCM) is located inside the transmission housing to reduce external wiring as well as to provide a constant environment for TCM operation. At idle it automatically selects neutral to reduce internal temperature and improve fuel economy. WD transfer cases can be fitted to the AWF21 for SUV applications.
