Hello Everyone...so I have a 3FE that blew the head gasket in one cylinder. It has almost 300k on the motor and tranny. I found and bought another 3FE with ~180k on it that I was going to strip and rebuild and then put back in. My question lies in what to do (if anything) to the tranny and transfer case. Is rebuilding the tranny myself a reasonable option? Same with transfer case?
