Hi all,
this link takes you to an SAE paper on the AW TF80 SC as fitted to the 3.2 in-line 6 and the v8. Need a subscription or pay per view I'm afraid.

Abstract

AISIN AW has developed a new FWD 6- speed automatic transmission “TF-80SC” for luxury cars with high torque engines. This newly developed automatic transmission (A/T) is based on the concept of the FWD 6- speed A/T “TF-60SN” that we have already introduced to the world market. The basic concept for the 6- speed A/T is to achieve weight saving and compact as well as better fuel efficiency and driving performance in comparison with conventional 5- speed A/Ts. Of course the shift feel must be the top level in the world, so we increased torque capacity of the TF-80SC to cover luxury cars with high torque engine. One of the outstanding features of the A/T is an advanced band brake that allows simultaneous pursuits of high capacity, weight saving, size reduction and high efficiency as well as high-quality shift feeling qualified for luxury cars. This paper describes the advantages and structure of the new A/T with a focus on our approach to new technology of the band brake system.
