Hi Scott
I would suggest you try Penrite's Gear Oil 30. It's a 20W-60 NON-Detergent
made and formulated for 50's, 60's, 70's gear boxes with/without overdrives.
It is safe with all yellow metals.
The detergent oils suspend particles that could clog the overdrives small
passages. The non detergent lets the particles settle out or if metal
stick to the magnetized plug, if yours is fitted with one.
Check out the web site or give me a call.
