Report: Lexus IS-F End of Production

On July 25th, the last unit of the Lexus IS-F rolled off its assembly line at the Lexus Tahara plant.

Latest Transmission Titbit – Aisin AA80E

Last week I have discussed the GM 8AT and the ZF 9AT, today let’s take a look at the Aisin AA80E, which is used in the Lexus IS350, GS350, LS460, IS-F and the upcoming RC-F.


Unlike other longitude mounted 8AT such as the ZF 8HP and GM 8L90, the Aisin transmission uses compound planetary gear sets. A compound planetary gear set is a planetary gear set that has multiple sun gears or multiple ring gears. There are different types of them, the one we are interested in is called the Ravingeaux gear set, which has two sun gears, two planet carriers and they share one common ring gear.

One Ravingeaux gear set can provide 4 forward gear ratios and also the neutral and reverse.
