AWTF-80 SC

The Aisin AW TF-8# SC series is a 6 speed automatic transmission designed for use in transverse engine applications. It is designed to handle a maximum of 440 N·m (324.5 ft·lbf) of torque. It is built in Anjo, Japan.[1] It is also called the TF-80SC[2] (AWF21, AF40-6, AM6, AW6A-EL) and TF-81SC (AF21).[3]

The design team set out to create a 6 speed automatic that fits in the same space as a manual gearbox. It measures 358 mm (14.1 in) in length and weighs 90 kg (198 lb). Its combined use of a conventional 5-pinion planetary gearset and a compound Ravigneaux gearset makes it incredibly light and compact. This combination is known as a Lepelletier arrangement. The shifting of gears is managed by a sophisticated computer programme which oversees a clutch-to-clutch actuation. Gear changes are accomplished by one clutch engaging the instant the clutch from the previous gear disengages. The transmission control module (TCM) is located inside the transmission housing, instead of being located outside it. The advantage of this is to reduce external wiring as well as to provide a constant environment for TCM operation which encourages longevity. One aspect of the advanced nature of the electronics is at idle, it automatically selects neutral gear to reduce internal temperatures and improves fuel economy.

It utilises a special AW-1 transmission fluid which is labelled as being maintenance free. It has a fluid capacity of 8.0 litres (1.8 imp gal; 2.1 US gal).

All wheel drive transfer cases can be fitted to the AWTF-80 SC, making it ideal for use in cross-over type SUVs.
