The Aisin AW TF-8# SC series is a 6-speed automatic transmission designed for use in transverse engine applications produced by Aisin Seiki. It is built in Anjō, Japan, and is also called TF-80SC (AWF21), AF40-6, AM6, AW6A-EL and TF-81SC (AF21). All-wheel drive transfer cases can be fitted to the AWTF-80 SC.
It uses a Lepelletier gear mechanism, an epicyclic/planetary gearset, which can provide more gear ratios with significantly fewer components. This means the Aisin AW TF-8# SC series is actually lighter than its five-speed predecessors.
The Ford 6R, GM 6L, and ZF 6HP transmissions are based on the same globally patented gearset concept. The AWTF-80 SC is the only one for transverse engine installation.
