It's the new trans going into the 2020 Duramax. Built by GM and modified by Allison. My friend at Allison said he spent 2 years with the trans.Indeed...what is it Mike?
thats not your shop :baby: .
Top secret for now.
Kind of reminds me of a 6R140 with the case and bell housing as one piece.
What's your friends opinion of this trans?!?! It's the bees knees?!?!
