Since the hour meter indicted only 500 hours on the engines/transmissions, I was hopeful that the transmissions were still good. The clutch packs looked great so I did not disassemble them. I just took apart the valving and the pump and cleaned everything up. I put in new gaskets and a new neutral safety switch. I have included a set of rebuild manuals if you wan to try a rebuild on your own —it’s not too difficult.
