I have just discovered what I think is an unusual problem. The np205 that I recently swapped into my 78 is sending gear oil up through the speedometer cable. It is not leaking much at the transfer case end, but the top end of the cable is leaking gear oil (this is a mess!). I am using the cable adapter off of the np203 to attach the cable to the transfer case. Is there some sort of seal internal to the transfer case that prevents gear oil from reaching the speedometer cable or is this only sealed externally at the cable adapter? Any suggestions? FYI: I did have the transfer case completely resealed by Standard Transmission & Gear in Ft.Worth before installing it, but it seems to be leaking somewhat from almost every place that has a gasket.
