You're right GMac, i don't see anything about the TCU on the ATS website. I'm almost positive they used to offer one with their label that they purchased from powertraincontrolsolutions.com. My buddy has been working on putting a Cummins and Allison in Clint Cannon's Super Duty, he occasionally makes parts for ATS. Both of their trucks have late model engines. Could you PM me your contact info that i can pass along so these guys can get their transmissions to shift as well as yours?
Thanks,
Matt
