hey all, i have a 89' f250 diesel with a BW1356 transfer case bolted to a ZF5 was just wondering is the tranny oil shared with the tcase? or does it have it's own oil supply?
the fill plug for a 1356 is on the rear of the t-case. You guys are right though, the transmission and t case are both sealed units and use their own oils, they do not share. I used to run transmission flud in my old 1356, what is best to run in them?
