I just sold my 96 Chrysler T&C with 352,000 miles on it two months ago.
The transmission gave up the ghost at 198,000, but that only happened because I bought the line that you could substitute other fluids for ATF+3. The second time the transmission went out, it was at 252,000, and the problem was the solenoid pack. No rebuild needed. The shop botched the programming, though, and it would sometimes downshift hard from 4 to 3 after that.
In revisiting that shop to have him get it right, he left a wheel loose one day, and it came off while my wife was driving down the highway at 70 mph with three kids and the dog inside. My wife, who earns title to the nickname "Andretti", got it safely to the roadside despite a flat-spotted rotor and messed up tie-rod end. A lawsuit ensued, and we were eventually recompensed for repairs and costs, but the hard 4-3 downshifts persisted for the next 100,000 miles right up until the day I sold it for $500.
Over its life, the thing visited 28 states and I used it as a delivery vehicle for a coffee service I ran for a while. I sold it because the body had taken some abuse in recent years (hit a deer, had someone back into it while parked twice) and it was due for a full slate of maintenance stuff (tires, brakes, struts), and when I added up the bills, I figured I could find something newer and nicer with less miles for the same money.
Selling it was like losing an arm. But I replaced it with an '01 GC that is treating me well so far.
