The Ford Barn - View Single Post - What oil is recommended for the Mitchell Synchro gearbox

I had the same question. Called Mitchel because I have both the Mitchel OD and the Mitchel synchronized transmission. I was advised to use 85w140 gear oil in both the OD and Tranny. They emphasized that GL5 was required. I now use this for the differential also.
