Okay, you were correct about all transfer cases fitting all trannies. Got the tranny and transfer case put together and was about to stab it when I had a thought. Now would be the time to drill the ports for an external pump for oil circulation while towing. I took the old transfer case apart to see where the best place would be for these ports. That's when I had another idea. What would be wrong with drilling and tapping a 1/8" pipe thread hole, in the aluminum case, about 1-1/2" above the fill plug and taking the oil level up about 1-1/2". The way I see it about 1/2" of all the bearings and gears would be sitting in oil at all times. I'm also thinking about either mixing half 90 weight and half ATF to thin the oil down, or even run straight ATF. I do run Royal Purple in everything I own, so it would top quality oil. BTW, purchased the Royal Purple 90 weight yesterday, $20 a quart.
