Sounds like its a E4OD with problems with either the MLPS, VSS or PSOM.
Verify which trans it is by pan,

Then run the self test, see what if anything it gives to go on. It might not throw a code however always best first place to start.

Check for proper adjustment/operation of the TV cable, if you haven't looked into that yet I'd start there.
If not sure how to set cable a simple "Google" search something like "AOD TV cable adjustment" will return many hits video and otherwise type "how to" on the subject.

tryed shifting manually it just stays in same gear never shifts but im thinking the tv cable does need adjustment because wen im in reverse the dash says im in park and wen in nutral says reverse and so on so possible adjustment is needed thanks for the info . will try adjusting today and see what happens

tv cable goes from throttle body on the engine to trans. It has nothing to do with the indicator.

Are you sure that you have a 1994? A 1994 did not have the AOD transmission, maybe a 1993?
As for the indicator that sounds like loose screws down near the floorboard.

This truck will have the first year for the 4R70W transmission, it basically is a electronic AOD, it also has a 14 bolt pan that is shaped like the AOD, and no TV cable.
The reason why it feels like it shift to neutral on the 3-4 shift is because the overdrive band is applied and the forward drum is released. So if the band cant hold it free wheels because the forward clutch released.
If I had to guess I would think that the band inside your trans is burnt and that your trans will have to be rebuilt. I would see this failure over and over in our shop.

Another 4r70w would be eaasiest. The aod would"work" but you would likely spend more on extra's to make it work (computer, etc) than just getting the same trans as you have now.
