My dad just recently passed away and I am now the owner of his 1989 F 150 XL 4x4 with a 4spd manual transmission. The truck has only 62k miles on it. My question is what kind of fluid does this transmission require? I am in the process of servicing the truck.
It seems like the majority recommends gear oil but the Ford do-it-yourself manual I bought of off Ebay states the manual transmission takes MERCON Auto Tranny Fluid part # xt-2-QDX.
Just trying to get the truck serviced before I deploy again in a few months.
