2003 CHRYSLER 300M Power Trainautomatic Transmission Problems

TL* THE CONTACT OWNS A 2003 CHRYSLER 300M. WHILE DRIVING APPROXIMATELY 50 MPH, THE CONTACT NOTICED THAT THE TRANSMISSION WOULD NOT SHIFT INTO THIRD GEAR. THE CONTACT RESTARTED THE VEHICLE AND IT FUNCTIONED PROPERLY; HOWEVER IT WOULD VIOLENTLY JERK WHEN SLOWING DOWN. THE DEALER WAS AWARE OF THE ISSUE AND MADE TWO ATTEMPTS TO REMEDY THE FAILURE BY REPLACING THE TRANSMISSION VALVE. THE CONTACT INFORMED THE MANUFACTURER WHO TOOK A COMPLAINT. THE VEHICLE WAS AT THE LOCAL DEALERSHIP AWAITING REPAIRS. THE CURRENT MILEAGE WAS 89,549 AND THE FAILURE MILEAGE WAS 62,036. UPDATED 03/22/11*LJ UPDATED 1/4/11 *CN

HAD JUST GOTTEN CAR BACK FROM DEALERS GARAGE FOR AIR CONDITIONING REPAIR. HAD DRIVEN LESS THAN ABOUT 10 MILES SLOW CITY DRIVING 35MPH MAX. WHEN SUDDENLY WITHOUT WARNING OF ANY KIND THE TRANSMISSION WENT TO FULL THROTTLE INSTANTANEOUSLY. HIT BRAKES, TRIED TO CHANGE GEARS, STEER OUT OF TRAFFIC, ALMOST IMPOSSIBLE TO CONTROL. FINALLY TURNED OFF THE KEY TO THE ENGINE. TURNED ON TWICE TO SEE IF ANY IMPROVEMENT. NONE. WHEN MECHANIC ARRIVED WITHIN ABOUT AN HALF HOUR AND TURNED ON ENGINE NO PROBLEM EXCEPT THE CAR WOULD NOT GO IN REVERSE. COMPUTER DIAGNOSIS SHOWED BUILD UP OF PRESSURE IN TRANSMISSION CODE OF SOME KIND AND THE MECHANIC ADVISED THE TRANSMISSION OVERDRIVE HUB HAD BROKEN. TRANSMISSION NEEDED REBUILT OR REPLACED. HAD NOT THOUGHT TO REQUEST DEALER HOLD OLD PARTS BUT JUST CALLED TO REQUEST THEM TO HOLD . *TR
