Check the sensors on the transmission. May just be corrosion on the sensors or it may be a faulty sensor. Also, the torque converter bearing may have went bad due to the running it on low transmission fluid.

TPS SENSOR.
IT CONTROLS SHIFTING AT THE RIGHT TIME
AND COULD ALSO CAUSE ALL OF THE SYNMTHOMS
THAT YOU HAVE LISTED SOMETIMES WITH OUT GIVING YOU A CODE GOOD LUCK

time to put a new tranny in that jet most of the time it costs to much to repair it then replace it i have done may tranny rebuilds and replacements to me i would just tell you to replace it at least you will get a better warrentee and stuff

COULD BE FAULTY 2 -3 SHIFT SOLENOIDS ALSO CHECK TRANSMISSION FLUID LEVEL.LOW FLUID LEVEL WILL CAUSE NO OVER DRIVE CONDITIONS. HAVE TRUCK CODE SCAN LOOK FOR CODE FIRST.DONT SPEND LOT OF MONEY GUESING.

It is a 5 speed manual transmission? If it is noisey in all gears except for 4th, then the problem is countershaft bearings.

Mine has a high pitched whistle at high rpms and I can't figure it out. But mines def not the tranny. I'm thinking it's a vacuum line somewhere. It's a 97 2.3l manual. The colder it is the louder...

If the whine is there than the main bearing is already worn adding fluid will not save it, you will have to swap it or rebuild it. sorry i know you were hoping for something better.

Providing there are no oil leaks at all, some transmission stabilizer may help. Any experience i've had with a whining 5 speed, is not good. Usually it's a bearing on it's way out. Try some of this, and see if it makes any difference. RISLONE® TRANSMISSION STABILIZER

check shift fork adjustment. make sure you bleed the slave cylinder.also check shift cable adjustment.

Well, I should be asking for more information, but since I am now on my 5th, yeah, 5th transmission in my 95 1500 Ram I have come to learn a little bit about them. Chrysler had a bad problem with their trannies in the 94's & 95's. They then made a change in 96, but that didn't solve the problem. So here goes my attempt to help you out.
Have you checked you tranny fluid level? Very important. A transmission kind of works under the same principal as a jet boat. Meaning, it pumps the fluid through the transmission much the same way a jet boat pumps water through it to move the boat, but in this case the fluid power is directed through several lines causing the gears to move. You switch gears when there is a certian amount of pressure on the modulator to divert the fluid to another area.
Long story short: Check your fluid, not only the level BUT the fluid. Are you seeing any metal in it? Dodge had a problem with the webbing of their torque converters flaking off, causing transmission cooliant lines to plug up. This same metal chips, shavings, etc. were damaging the face of the clutches, and plugging up modulators. Check your fluid. I would probably say change your fluid and transmission filter. It's not that big of a job if you have a place you can work on your vehicle. Be careful when putting you transmission pan back on. Make sure you tighten the bolts in a crosswise manner, and tighten them snug, BUT not over tight. That will cause leaks.
Another point I will make. Check for vacuum leaks, this could very well be your culprit too.
I'd start with that first.
Good luck, let us know how you come out.
