Answer
Hi Mhel,
If you take the car to a shop that you trust and which has a fault code reader which plugs into the socket under the dash that shop should be able tell you any faults that the engine controller and the transmission controller has noticed. These are 4-digit numbers preceded by a P. Ask them what the number are, what they mean, how much it will cost to fix. Then write me back and I can compare what they tell you to what the shop manual says about those fault codes. It doesn't have to be a Chrysler dealer, but any shop that has what is called an OBD-II code reader for American cars of any make. It is probably an problem with the engine, not the transmission.
