If your trans. is a 5 speed, its pretty common. Not enough transmission for the motor. I broke my trans. (different gears & shafts) including the 5th gear 4 times before I bought another transmission. Had I known then what I do now, I would have switched over to a 6 speed like whats in my 03 truck now. I put the upgrade parts for the 5th gear in but the simple fact is that the 5 speed belongs in a car, not behind a Cummins.
