- The Aisin AW TF-8# SC series is a 6-speed automatic transmission designed for use in transverse engine applications and produced by Aisin Seiki. It is designed to handle a maximum of 450 N⋅m (331.9 ft⋅lbf) of torque. It is built in Anjō, Japan. It is also called the TF-80SC (AWF21, AF40-6, AM6, AW6A-EL) and TF-81SC (AF21). The design team set out to create a 6-speed automatic transmission 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 program that 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 (along with required foot brake depression on e.g. Opel Astra), it automatically selects neutral gear to reduce internal temperatures and improve the fuel economy. It is a sealed for life unit, using proprietary transmission fluid which is labelled as being maintenance free. However, for vehicles used primarily for towing, taxi or in mountainous environments transmission fluid change every 60,000 km is recommended. Transmissions made before year 2011 (generation 1) use JWS 3309 standard oil, while transmissions made from year 2011 (generation 2) use JWS 3324 standard oil. Saab versions of the transmission use AW-1 Mineral oil. All wheel drive transfer cases can be fitted to the AWTF-80 SC. (en)
