    Temps were good pressure was good all the way out there it did sit for a few years before it was ran again and then these problems started.

    No s/n, no pressure tests = no answers.

    I'm confused is this a direct drive or power shift. oil filling up final drive is pinion seal on final drive most likely loose pinion bearings. You say that it pops out of gear and grinds. that makes me think it is a direct drive if it is trans has to come out and be rebuilt. Steering could be your steering clutch seals did you replace them when you had the steering clutch out normally loose bevel gear bearings will knock out the seals
