NORMAL DRIVING RESULTS IN A CHANGE IN THE SHIFTING ACTION OF THE AUTOMATIC ELECTRONIC TRANSMISSION. IF THE VEHICLE IS WARM THE ELECTRONIC BUZZ LENGTHENS AND PREVENTS THE SHIFTING FROM ONE GEAR POSITION TO THE NEXT. THE TRANSMISSION RUMBLES AND SKIPS BEFORE CHANGING TO THE NEXT GEAR FOR A SECOND OR MORE. THE GEARS CLEARLY ARE NOT ENGAGING IN A TIMELY MANNER AND PREVENTS READY MOVEMENT AFTER SHIFTING TO A NEW GEAR POSITION. AFTER LONG DRIVES THIS IS NOTICEABLE DURING NORMAL UNHURRIED PARKING MANEUVERS. THIS ACTION WAS INITIALLY OBSERVED AT ABOUT 384 MILES ON ODOMETER AND BROUGHT TO THE ATTENTION OF THE DEALER. THE SECOND PROBLEMS HAS OCCURRED ON 5 OR MORE OCCASIONS WHERE THE IDLE SPEED DOES NOT GO TO NORMAL AFTER REMOVING PRESSURE FROM THE ACCELERATOR. WAS FIRST NOTICED ON HILLS IN CITY OF SAN FRANCISCO AND HAS BEEN NOTICED IN TRAFFIC ON SEVERAL OTHER OCCASIONS. THE ENGINE NOISE IS QUITE AUDIBLE WHEN THIS OCCURS AND IDLES ABOVE 1000 AND CARRIES VEHICLE AT 10 PLUS MPH ON FLAT SURFACES. THE VEHICLE ALSO SURGES AFTER SHORT DRIVES AND IS NOTICEABLE IN PARKING LOTS OR GARAGE PARKING. THERE HAVE BEEN THREE "DANGEROUS" INSTANCES WHILE IN TRAFFIC. THIS WILL OCCUR IN BOTH REVERSE AND FORWARD DRIVES. THE DRIVE TRAIN ALSO HAS A LOUD RESONATING SOUND WHICH SOUNDS AS THOUGH THE ROTATING IS NOT UNIFORM AT LOW SPEEDS. THE DEALER SAYS THIS IS A NORMAL SOUND. ALL OF THESE CONCERNS WERE OBSERVED AFTER ABOUT 300 MILES AND BROUGHT TO THE ATTENTION OF THE DEALER. THE DEALER DOES NOT ACKNOWLEDGE HEARING THE GEAR SOUNDS, SAID THE IDLE WOULD ADJUST AFTER 3600 MILES AND HAS NOT ADDRESSED THE SURGING. *NM
