I'm getting an 87 F150 this afternoon with the 4spd manual transmission. I called the Ford dealer and he said his book only goes back to 1988 but that it recommends an ATF for their manual transmissions. What is everyone else out there using for a manual trans? ATF sounds to light.

Please forgive me if I ask all the stupid questions but I'm not real experienced in automotive work. This vehicle is a project for me and my son.
