we have a Caravan too
a '95 Caravan with > 150,000 miles. The only problem we've had with the tranny is a leaky seal. We've been putting transmission fluid in it every couple of thousand miles for the past 3 years. Recently we've had trouble with the brake lights not going out. Seems to be an issue with the sensor on the brake pedal. Other than that it's been great. If you can find a used one that hasn't had transmission problems, or one that has had it's transmission problems fixed, you can probably get a good deal on it.
Have fun,
