ATTN: Do not do business with “next gen drivetrain”. Scammers, crooks and liars! Bought a supposedly built trans for my truck and it was nothing but stock generics parts that failed. I called them super nice and asked for a build sheet for the bullet proof trans they sold me and they lied to me and blew me off! I was given huge sales pitch and the guy was good and I fell for it. I hope this helps save someone else’s hard earned money!
