Default 1994 Mustang GT, transmission AOD-E issue

hey everyone. Car in question is a 1994 mustang gt with a AOD-E transmission. the problem is that is shifts into the next gear to soon sometimes. where when it shifts into next gear, the rpms will be around 1k rpms then it acts sluggish. it does not do this all the time though. another problem is that sometimes when the transmission shifts from 3rd to 4th(OD), it acts like it gets hung and the rpms bounce from 1k to 1200 rpms. if you go ahead and give it some gas, it doesnt act like its bouncing back and fourth. the TCC(Torque Clutch Control) solenoid and the transmission fluid temp sensor was replaced. this bouncing started after the TCC solenoid was replaced. I think those bad parts were *masking* another problem. Another issue is that when you put the automatic gear shifter into second gear, it doesnt shift from 1st to 2nd and stay there, from a dead stop it start in 2nd, and then almost stalls then it will shift into 3rd. The owner has replaced all the fluid and replaced the transmission filter, and the fluid level is correct. also, there were no codes for the transmission that showed up. sorry for the long post, just trying to give all the information needed. Thanks everyone.

Sounds like a sensor problem. Either MLPS (manual lever position sensor) or TPS (throttle position sensor).

the tps sensor voltage is right where it should be, also there is no codes showing for either the trans or the engine sensors. has anyone else had a similar problem? all help is greatly appreciated.

Sounds like it's in need of a rebuild. Get a shift kit while your at it. Only otherthing is mlp or how some auto parts store have it under "nautral safety switch"

Outside the transmission on the driver's side. Not hard to find.

wouldn't the pcm though a code though if it was a sensor for the transmission? the transmission has days where it does better and others it doesn't.
