Has any body experienced a rear end clunk in 02 2500HD duramax truck with allison transmission when taking off from a stop or when coming to a complete stop. It does not go away no matter what you do!! It seems its in the rear end or maybe the springs. I need help I have taken it to 2 chevy dealers and nobody can pinpoint. It sounds like when torque is taken off the rearend it doenst just stop tight it creates a backlash feeling
