Default 700r Tranny problems

A friend of mine justgot a 1989 chevy c1500 with a 700r tranny atleast thats what he told me it was anyway. The problem is that the tranny shifts from first gear to second and then when it trys to shift into thrid it goes back to first. The tranny fluid on it looked shot so I told him to get it flushed and see what happens then. Do you think this would help or is the tranny cooked? Before it started shifting like this when you were wide open it would take a long time to shift gears. So would flushing the tranny fix these problems or is it more likely that the tranny is shot? When he first had got it it shifted fine besides taking along time at WOT to shift, then he had it out on the ice track beating on it some and it started doing it as we were leaving. The fluid was pretty black looking and smelt burnt. Thanks for any help!

Sounds like a rebuilt is the best bet. Sounds like the clutch plates are worn or warped!

Oh is there any chance that it could just be a problem with the fluid? Or does it need to be rebuilt for sure? Thanks!

Well about the only thing that would have a burning smell will be the clutch plates. Late shifting is also a sign of worn or warped plates so in my opinion you absolutely need a rebuild. Changing the fluid wouldnt make much of a difference. To be sure wait for some other opinions.

Alright thanks well if the tranny is shot I think I might be able to pick it up from him for 2-500 and fix it up myself. He triedusing someadditive stuff because hes tocheap to get it flushedand says now it shifts out of first hard. He is also still driving it even though he doesn't need to...not the brightest kid. Thanks for the help!
