Auto Transmission Problem 94 GC

I have a 1994 Jeep Grand Cherokee Limited, 4.0L 4x4

It started having issues a couple weeks ago, first when you were driving it it would all of a sudden not want to shift, and the only way to get it to shift would be to floor it. Also sometimes it would seem like it would shift into a higher gear then it should have, leaving it running at much lower RPM's then it should. From there it got progressively worse, it wouldn't even shift if you tried flooring it, and then now you can get into it and start it, but when you move the shifter into any of the gears it will not move. It doesn't even sound like its shifting into the gear. If you sit on the gas with it in drive or reverse sometimes it will catch into gear and start to move, but when it does it makes a loud winding type noise. It'll drive for a little bit (a minute or two) and then it'll just start acting as if it's in neutral again.

When it first started happening we changed the transmission fluid to see if that would help at all and it did not. There didn't appear to be any excessive shavings in the pan either.

There is no check engine light on, and I checked to see if it was throwing any codes but it is not throwing any transmission or engine codes.

Any help would be much appreciated, if I need to clarify anything please do ask.

Verify correct fluid level. Park level, tranny hot, shift slowly through all gears, leave shifter in N, check fluid level.

Looks like the transmission fluid level is higher then what it should be, gonna check it again here in a few to make sure I read it correctly yesterday. If its still reading high I'm gonna open the pan up and drain it all again and refill. Going to also change out the Governor pressure solenoid and sensor while I'm in there.

Well popped open the tranny pan and drained some of the fluid, that fixed the issue of it not going into gear. But when driving it it has issues in 1st and 2nd gear, once it hits 3rd it runs fine. From what ive read on here that does sound like the governor solenoid correct?

Thanks for the help so far!


EDIT:

I only opened it enough to drain some of the fluid to get the level where it needs to be to see if that'd get it going and it did. I ordered the Governor Solenoid and sensor already, hopfully get that at the end of the week and get it in.

This was worth every penny to me - http://www.cascadetransmissionparts....cekit9697.aspx

Even though I had no loss of overdrive, it turned out my accumulator spring was in pieces anyway. I used everything in this kit but the gasket. My pan wouldn't stop leaking, so I ended up with the Mopar OEM transmission pan gasket and it hasn't leaked a drop since. I have put on 2,000 miles since this kit and it shifts and drives so much smoother.
