no one knows if type f can be ran in a non lock up A-518?




I wouldn't. As stuff get's newer it get's pickier.

Back to the thread, this debate comes up once in a while, but is really moot.

The 727 and 904 are kinda like the cave men of automatics. They work, and work well, with almost any kind of fluid. I've seen guys on here testify to using straight engine oil, cause it would lubricate better.

In any case, will type f work? of course, and wont hurt anything that was any good to begin with..

My question has always been, and will always be, why would you bother? Even ford gave up the stuff in 79. Modern fluids are MUCH better suited for extreme temps etc.

We could use Bias ply tires, and they would work fine, but clearly there is better stuff out there, and the same goes for type F.

FWIW I use either Mercon 5 or atf plus 4 whatever the current stuff is
