I have a stock 1967 cj5 with the v6 3 speed. The transfer case is leaking out of the speedometer cable that is higher then the fill plug. When I drain both the transmission and the transfer case then fill them both to there fill hole I drive it a few miles then check the levels. The transmission is low and the transfer case is overfull. Oil is getting into the tc then not getting back into the transmission. I called a local gear shop with a good rep and they said I would have to pull the transmission with the tc attached and bring it in so they can find the problem. Has anyone heard of such a problem?
