Hey sorry man for not reporting back. Drivetrain clunk is definitely not solved but I think it's a little better. Most noticeable in second gear. I know whatever my problem is, it lies in the transmission and I dont want to tear that thing down again for quite some time. My rough guess would have to be the VCU but at $3000 that thing can clunk all it wants...
EDIT: Dude, try the zip tie fix for the C.B., that shit does work for C.B. play. Mine have held for 3 months so far. Plus a bag of big zip ties is like 6 bucks at Depot..
