c6 problems

im having problems with my 89 f 150. reverse works great, goes right in and grabs, but when i put it into drive 1 0r 2, it doesnt, pretty much at all. if you rev it up good it will grab and be fine for a little bit and drive normal then after a while it will go back to where you have to rev it up again to grab. any ideas? i thought maybe filter and trans fluid. or a rebuild. its an 89 f150 351w with the c6. any help would be great. thanks

not expert but have 3 C6 here

I learn in transmission class.


What color fluid is?

did it feel slipping?

Do you know how to check pressure in that transmission?



If it was me I would have rebuilt but first check basic stuff before rebuilt.

Sounds like a low fluid situation to me. Don't forget to check it hot, idling in park.
