2004 BMW 5 SERIES Power Trainautomatic Transmission Problems

VEHICLE LUNGES FORWARD AT LOW SPEEDS SUCH AS PARKING; 4 TIMES IN THE LAST MONTH, WHEN I AM PULLING OUT OF A PARKING SPACE, THE VEHICLE HAS LUNGED FORWARD. 2 OF THOSE 4 TIMES, I ALMOST HIT THE VEHICLE IN FRONT OF ME. I HAD SHIFTED FROM REVERSE, TO DRIVE, AND JUST TAKEN MY FOOT OFF OF THE BRAKE, AND THE VEHICLE JUMPED FORWARD. THE DEALER HAS CONTINUED TO SAY THAT THINGS ARE OK AND NORMAL. THEY ARE NOT NORMAL. ADDITIONALLY, I HAVE OTHER SHIFTING ISSUES BELOW: --35MPH (5TH TO 6TH HESITATION) 5-6 HARD SHIFT (SPORT MODE GOING 45-55 MPH) SLOW TO ENGAGE REVERSE -- GEAR SHIFTING IN GENERAL IS JUST SLOPPY (THE LOANER THAT THE DEALER PROVIDED, SHIFTED GREAT). *TR

HAD MY CAR 2004 545I (78,250 MILES) SERVICED AT BMW DEALERSHIP IN LONG ISLAND FOR A DEFECTIVE TRANSMISSION PAN LEAKING AT FLUID. DEALERSHIP REPLACED AND TEST DROVE BEFORE I PICKED IT UP BUT ALSO DENOTED THAT THERE WAS AN OIL LEAK ATTRIBUTED TO VACUUM PUMP/VANOS SEALS WHICH NEEDED TO BE REPLACED SOON. AS I WAS DRIVING IT BACK TO NJ FROM LONG ISLAND DEALERSHIP I NOTICED A TRANSMISSION 'KICK/JERK/SURGE' AS CAR DECELERATED SEVERAL TIMES. DROVE THE CAR TO THE MARKET ON SUNDAY (7/25/2010) AND ON THE WAY BACK WARNING ENGINE MALFUNCTION STATING 'ENGINE OPERATING AT REDUCED OUTPUT'. EMAILED THE BMW SA IN LONG ISLAND THAT REPLACED DEFECTIVE TRANSMISSION PAN/AT FLUID AND HE FELT IT MAY BE ATTRIBUTED TO OIL LEAK AND BAD VACUUM PUMP/SEALS AND HAVE IT LOOKED AT ASAP. MY LOCAL BMW SA IN NJ JUST EMAILED ME TODAY (7/28/2010) STATING: "LOOKS LIKE THE TRANS IS BAD WAITING FOR...

1. I IDENTIFIED A PROBLEM WITH THE 2004 BMW 545I WHICH I HAVE. I RESEARCHED THE ISSUE, WHICH I WILL EXPLAIN BELOW (IN SECTION 2 AS REQUESTED), ONLINE, AND FOUND THAT HUNDREDS OF PEOPLE HAVE HAD THE SAME ISSUE. I FOUND THAT IN SOME INSTANCES, BMW CORRECTLY DIAGNOSED THE ISSUE, HOWEVER IN MANY INSTANCES, THEY DID NOT (IN SECTION 3, AS REQUESTED). 2. "THE CAR WOULD SHIFT INTO 5TH GEAR & THEN BETWEEN 35-40MPH AT A VERY LOW 1200RPM OR SO I WOULD GET THE SURGING OR SLIPPING OF THE TRANSMISSION. IT WAS A VERY LIGHT REPETITIVE HESITATION. IT ALMOST FELT LIKE THE ELECTRONICS WERE TRYING TO DECIDE WHETHER IT SHOULD STAY IN 5TH OR SHIFT BACK TO 4TH BECAUSE OF LOW RPM'S. IT WOULD HAPPEN WITH AN EXTREMELY LIGHT ACCELERATOR PRESSURE. IF YOU GAVE IT A LITTLE MORE GAS IT WOULD GO AWAY. A COUPLE TIMES I'D GET A...

TRANSMISSION SLAMS INTO GEAR WHEN TAKING OFF FROM AN ALMOST STOPPED POSITION CAUSING THE VEHICLE TO JUMP FORWARD VIOLENTLY. THIS HAS LAUNCHED ME INTO INTERSECTIONS AND CAUSED ME TO ALMOST REAR-END SEVERAL VEHICLES. THIS HAPPENS ON A WEEKLY BASIS OF DAILY DRIVING. THE DEALERSHIP WANTS TO REPROGRAM THE TRANSMISSION COMPUTER AT A COST TO ME(VEHICLE OUT OF WARRANTY) EVEN THOUGH THIS IS A KNOWN PROBLEM. *TR

TL*THE CONTACT OWNS A 2004 BMW 545. THE CONTACT WAS DRIVING APPROXIMATELY 10 MPH WHEN THE ACCELERATOR PEDAL WAS ENGAGED, THE VEHICLE BEGAN TO SHUDDER. THE VEHICLE WAS TAKEN TO THE DEALER WHO RECOMMENDED THAT THE TRANSMISSION BE REPLACED; AND OFFERED TO PAY FOR HALF OF THE REPAIR COST. THE VEHICLE HAD NOT BEEN REPAIRED WHEN THE COMPLAINT WAS FILED. ADDITIONALLY, PRIOR TO THE TRANSMISSION FAILURE THE VEHICLE WAS TAKEN TO THE DEALER IN REGARDS TO A BURNING ODOR AND A TRANSMISSION FLUID LEAK IN WHICH THE VEHICLE WAS REPAIRED. THE FAILURE MILEAGE WAS 73,000. THE CURRENT MILEAGE WAS 74,100.

CAR SUDDENLY AND VIOLENTLY LUNGES FORWARD FROM A STOP, SLOW SPEEDS OR WHEN AT LOW RPMS. IT OCCURS SEVERAL TIMES PER DAY AND IT FEELS AS IF BEING REAR ENDED.
