Slim was and my mrs car still is running the 4ac driveline, Slim's had a puck clutch and would get clutch dumps without breakage (until the new owner got it :lol:), The missus car is auto, It has done on the limiter neutral drops, burnouts and all kinda crazy shit (don't read this either you 8itch) and the running gear is still intact, You are either way to rough or did not do them up properly.
