Anyone knowledgeable on the Aisin (Ram) 6-speed?

BTW - we are still struggling to get warranty work done. The turbo replacement was denied under warranty. Dealer is still dragging their feet on the transmission replacement, so we can't tell what is going on with that. We may tow the truck back to our shop later this week if progress isn't made. We could have already done the turbo and dropped the trans ourselves, in the amount of time the FL dealer has sat on it.
