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.
no do not put gear oil in that 4 speed. the old 4 speeds use gear oil, the old cast iron ones. all ford aluminum case manuals use atf. had a 4 speed from an 87 in my truck a while back, same problem noone knew what to fill it with. ended up finding a ford part number at one of the parts stores and it was just regular old atf. i put in about 30% of lucas trans medic to shut up the syncros. gear oil will trash that cause it is to thick wont lube the input bearing enough. if its cast iron, gear oil is fine, aluminum is atf
ok well i guess i should just come on here for any of my questions from now on cause i asked 2 trans shops around my house and a parts guy at the dealer and they all said if its aluminum its atf. was confient that they knew what they were talking about so i didn't look anything up, just did, says use gear oil. now ifeel like an a**. sorry all
^^^ Agreed. Im a fleet mechanic for a living, and I can tell you unless the people you talked to were only months away from retirement, they probably were not working on an 88 when it was new. The younger mechanics probably have heard that "unless that ford is old as dirt, the manuals take atf." And heck, your truck has EFI, so it cant be that old... right? Most public mechanics have no idea about anything older than about 97-98, its all they ever work on, and all they want to know about.
Ok so I have a small leak in my tranny and was wondering the same thing. Its a 1989 F150 with the 6. Manual transmision, and wondering when I add fluid is there anything I can add to help stop the leak?
A manual trans leak is something that needs to be fixed. First, find the leak, its either a rear seal, a front seal, posibly a rubber plug etc. But find it and replace it. Usually its not a difficult task.
