I have a 1995 Caravan SE that would jerk and slip, and after a little while, had problems staying on at all. The problem ended up being the transmission strainer being dirty. Sounds like that could be your problem as well.
If it is, consider yourself lucky. It's the most inexpensive repair you could hope for, and it can likely be done without the help of a mechanic in your own backyard/driveway. All you need is a ratchet and something in which to dispose of the old fluid.
The strainer cost me $12 (plus tax) at autozone (it comes with the gasket for your tranny pan). Add in the cost for 6-7 quarts of transmission fluid and some compound for the new gasket, and you could be looking at a $50 fix for your problem.
All you have to do is drop the transmission pan, and you'll see the strainer right there in plain sight. It's about 5"x7" in size. You can pop it right off with your hand. Then, just put the other one on (push firmly until it snaps into place). There's only one way to put it on, so no way to mess up the installation.
Scrape the remnants of the old gasket from the drip pan so you get a good seal with the new gasket.
If you have a gas can or container, get some gas to clean out the drip pan thoroughly, making sure you also clean off the magnet that is there to catch deposits.
Put your gasket on your pan, then put the pan back on and add your tranny fluid. It'll likely take 7 quarts for the fluid to register on the dip stick.
Then, just start her up and drive it around, paying attention to how the car reacts when it switches gears. If it's smooth sailing, that was your problem.
