The rear half of the Trans.. Planet,Bushing output shaft and Rear case washer was all Burnt up... The good thing was the Rear case bushing was a wipe out BUT didnt spin out in the case.. Yes I know I rode in the truck and it shifted fine but It also bunt 1.2.3 clutches 3rd was toast.. I have been looking threw the shift kit that was installed to see if there was a problem but So far the only big thing I have seen is the Boost valve spring on the backside of the pump was not changed with the one in the HD2 kit... I am not that worried about the trans since I didnt have to Buy another Core..
