I HAVE A YEAR WITH MY VEHICLE AND IT HASN'T GAVE ME ANY PROBLEMS UNTIL NOW THAT THE AUTOMATIC TRANSMISSION FLUID NEEDS TO GET DRAINED. THE GEARS WONT SHIFT CORRECTLY.RPM'S FEEL AS THOUGH THEY ARE NOT RISING PROPORTIONALLY TO THROTTLE INPUT.THROTTLE RESPONSE FEELS DEAD IN CERTAIN INSTANCES.SOMETIMES THE CAR WILL CHIRP/SPIN THETIRESOFF THE LINE AND THE RPM'S RISE QUICKLY, OTHER TIMES YOU CAN FLOOR THE CAR OFF THE LINE AND GET ABSOLUTELY NOTHING.GENERAL SLUGGISHNESS IN ACCELERATION -SIGNIFICANTLY INCREASED DROP IN RPM BETWEEN SHIFTS. SO I LOOKED IT UP AND I FOUND THIS ARTICLE ON 300 CARS THAT FROM THE MAKES 06-10 WITH RWD MODELS THE 42RLETRANSMISSIONUSES 'EMCC'.THE WAY IT IS PROGRAMMED TO OPERATEIN THIS 4 SPEED TRANSMISSION CAUSES SERIOUS DRIVABILITY ISSUES ATORQUECONVERTERCLUTCH IN AN AUTOMATIC TRANSMISSION WILL LOCK/UNLOCK AT CERTAIN SPEEDS, BUT THETORQUE CONVERTERCLUTCH IN THE42RLEDOES NOT OPERATE AS CHRYSLER DESCRIBES IT IN THE OWNER'S MANUAL.

VEHICLE HAD TROUBLE SHIFTING INTO NEXT GEAR AFTER LEAVING FROM A STOP AND ACCELERATING. THIS OCCURED IN THE BEGINNING GEARS, BUT NOTHING WITH THE HIGHER UP GEARS. TRANSMISSION GETS CHECKED EVERY 3,000 MILES WITH THE OIL CHANGE. *TR
