I have a 1994 Dodge Ram 1500, and just the other day i was driving home and saw my RPM jump to about 3000 (was running at only about 1500 - 2000 before that). I didnt think anything of it. About a mile up the road it happened again, but this time i could not accelerate (like i was trying to drive in neutral) Occasionally the engine would connect with the transmission and i could drive a few feet before it would disconnect again. I just parked it out in a parking lot until i could get it going enough to make it home.
Now when i start the truck (while its cold) everything seems to run fine, but as soon as it gets a little warm there is a loud grinding noise (like the gears on a diesel engine) that comes from the transmission. Is it possible that this sound is actually coming from the torque converter (maybe the stator's clutch went out??) It also whines as i accelerate relative to the RPM
(fluid has been checked and is good and full).....
Thank you very much for your answers.

Another thing is that it only does this after being in gear for a little while, i spoke with a couple people and they said that it was probably the front pump. If this is the case, would i HAVE to get a full overhaul on the transmission, or is it possible to just replace the pump?

you have definately described a torqueflite torque convertor failure. it won't move for much longer. that buzz/whine is the convertor. it changes when you put it in gear, right? take it to a trans shop, or a dealer. it will need a thorough going through. when these convertors go, they send tons of very fine metal through the pump, into the cooler, and throughout the whole trans. its in the solenoids, valve body, everywhere. if you drop your pan, you will see what looks like very fine glitter, some brass, some aluminum from the stator. because of everything that needs to be replaced, this could get expensive. i did have one that i replaced the pump and convertor, flushed the trans 2 times, and it never had any more problems, bu this is lucky, don't get your hopes up quite that far yet.

OK Joe, the converter has a substrate biscuit inside the outer shell. A car/truck that has been misfiring will eat the converter. Think of the converter as an air filter in reverse a filter for the exhaust. Therefore an un-tuned engine that is not burning all of the fuel delivery i.e. running rich. The converter is being polluted with to much fuel. After to long the biscuit that will only flow one way could become cracked and Lodge in the Ex. flow which can cause a major lack of power. The year of your truck is right on the borderline and could also have a pellet type converter. The results are the same except the pellet type does not have a biscuit. Rec. have the converter inspected and or replaced. To learn more about converters and how they work check out carsound/magnaflow on-line or eastern converters.

Dodge Ram Torque Converter Problems

Could very well be the converter is bad and causing the engine to "flare up" while driving or it could be one of the bands is slipping or a friction clutch is slipping....if you drop the trans fluid pan and find very little worn clutch material in the bottom, I would suspect the t-converter is bad but it could be caused by low oil pressure too not fully engaging the bands or clutches. Would have to run a pressure test of the trans to determine if it's correct. If it's fine when cold, it doesn't sound like it's the converter which would be bad all the time if the vanes are broken....more likely a slipping clutch or band which are tighter when cold and loosen up tolerances when hot. Might just be better off with a rebuild or new trans.

It does sound like you have a converter problem and as sprinkles stated you probably have a bunch of shavings all throughout your transmission.
