Taking the top off the AA tranny today. I finally found some heavy gear lube. Lucas 85-140. Can't find any single weight that thick around here.

Believe it or not the correct oil the Ford used is 600W vegetable oil. It’s used in the meat packing industry. Valvata is the Shell oil product. Probably only find it in 5 gal pails. Would that not be considered synthetic oil?
