I just recently installed a fresh motor / transmission / transfer case in my 1968 FJ40. Still have the interior transmission hump cover out and shifter out. The renewed tranny and tcase were shipped dry by Valley Hybrids (with a big reminder tag to add lubricants before use).
I plan to add oil to the transmission and transfer case after I install the vacuum shifter pod I’ve been refitting. A buddy suggested I could put the recommended quantity of gear oil into the transmission directly via the gear shift orifice inside the FJ, since the cover and shifter are already off. (As opposed to pumping gear oil into the fill port underneath til overflow.)
I would still want to install fresh crush washers and carefully torque the drain/fill bolts from below.
Buddy also wondered if transmission and transfer case co-mingled oil. I think not… (why would they have separate drain and fill plugs) but would appreciate an authoritative response to pass on.
I plan on adding oil to the tcase from underneath the truck and will likely just pump in the fresh transmission oil while I’m there with new crush washers… but is the option to add tranny oil via the gearshift hole up top a real thing?
Thanks again for the help.
