It seems like i might be having yet another problem with my trans.! IT had been working great since i rebuilt it but the other day only after it gets hot it seems to act up a little again not wanting to shift! But it only does it when it gets good and hot and it don't do it all the time just once in a while,could it maybe be a piece of dirt hanging up in it somewhere or could it be something else?

One other question kind of related,do these trans. have some kind of governor on it that won't let it over-rev?
I ask because after i kick it into passing gear and then if i put it right down on the floor it basically comes out of gear but if i let off the throttle it goes back into gear.
I don't know if it did this before i just noticed it the other day. Could this be yet another problem?
 
Did you replace the PRESSURE SENSOR and PRESSURE SOLENOID in the GOVERNOR when you rebuilt the transmission?

My truck wouldn't shift like it should when the transmission got hot (normal temperature). I ended up replacing those two parts and I had no trouble after that. The PRESSURE SOLENOID is very prone to get dirt hung up inside it and will cause this. If you notice the PRESSURE SOLENOID has a very fine screen in the attempt to keep dirt out. My truck did exactly what you are describing in both paragraphs that you posted.

Yep i replaced the governor solonoid and the pressure transducer,the only thing i didn't replace was the speed sensor.
It's a 97 Ram 46RE trans.

I didn't have to replace the speed sensor.

There is one other thing you could try and that is adjust the Throttle Valve cable which is located on the throttle body. But that is mainly to fine tune the shift points but if the cable is off just a tad it will make a difference. Do you know what I'm talking about?

Copied:

THROTTLE VALVE CABLE
DESCRIPTION
Transmission throttle valve cable (Fig. 244) adjustment
is extremely important to proper operation.
This adjustment positions the throttle valve, which
controls shift speed, quality, and part-throttle downshift
sensitivity.
If cable setting is too loose, early shifts and slippage
between shifts may occur. If the setting is too
tight, shifts may be delayed and part throttle downshifts
may be very sensitive.
The transmission throttle valve is operated by a
cam on the throttle lever. The throttle lever is operated
by an adjustable cable (Fig. 245). The cable is
attached to an arm mounted on the throttle lever
shaft. A retaining clip at the engine-end of the cable
is removed to provide for cable adjustment. The
retaining clip is then installed back onto the throttle
valve cable to lock in the adjustment
