From what I understand, automatic transmissions in front-drive Chryslers are trouble-prone, and many of the problems stem from not using the factory recommended fluid.
Our ‘98 Sebring convertible has 141,000 miles on it so far, and thankfully the transmission has not had any problems.
He had never changed the fluid, ever, and he bought it new. In fact, the 60K transmission problem was the second time this happened. The first was at 40K, which was covered by the factory warranty. The second time cost him a couple of grand, since it happened just after the warranty expired, on account of mileage.
