I found my overdrive problem thanks to Leo Ruof and John from Quantum Mechanics. Stuck cone clutch.
Now I am ordering the gaskets and seals to put it back together and I'm totally confused as to what kind of oil to use.
Leo (veteran of 300+ OD rebuilds) is adamant for SAE 20-30 as is the Laycock shop manual (PUBLICATION PART No. 502274). On the other hand the owners manual (p 16) and other sources are recommending GL4 80-90 wt gear oil.
What say you all?
