NHTSA Complaint #10394263 — 2004 BMW 745LI

VEHICLE TYPE IS A 2004 745LI BMW V-8 6 SPEED TRANSMISSION. WHEN THE CAR IS IN 5TH GEAR THE CAR HICCUPS LIKE IT WANTS TO UP SHIFT BUT THEN DOES NOT. IT CAUSE THE CAR IT JERK EVERY 3 TO 5 SECONDS WHEN IN 5TH GEAR. WHEN THE CAR IS IN ANY OTHER GEAR IN DOES NOT DO THIS. I HAVE HAD A TRANSMISSION FLUID COMPLETELY CHANGED OUT. IN WHICH THE FLUID SMELLED BURNT AND LOOKED BROWN IN COLOR. BMW SAYS THAT IT IS A LIFE TIME FLUID (IT IS NOT). WHEN THE CAR IS ACCELERATING THROUGH 5TH GEAR IT DOES NOT DO THE PROBLEM EITHER. THERE IS SOMETHING CLEARLY WRONG WHICH THE TRANSMISSION. I HAVE TAKING THE CAR TO TWO INDEPENDENT TRANSMISSION SHOPS AND THEY HAVE NO IDEA. I HAVE LEARNED THAT THE CAR WILL STAY IN 6TH GEAR AT 45 MPH AND NORMALLY CRUISE IN THE CITY IN 4TH GEAR AT LOWER SPEEDS AND AVOID 5TH GEAR WITH THE USE OF THE MANUAL SHIFTS ON THE STEERING WHEEL. ALSO, THE DYNAMIC DRIVE SYSTEM FAILS ABOUT ONCE A MONTH IN WHICH YOU CAN TURN THE CAR OFF AND ON AGAIN AND THE CAR DYNAMIC DRIVE SYSTEM WORKS FINE FOR A MONTH OR SO. THIS CAUSES THE CAR CHASSIS TO ROLL WHEN CORNERING. DURING THIS TIME OF FAILURE THE STEREO MAKES ODD NOISES IN WHICH I THINK IT IS BECAUSE THE STEREO VOLUME IS SET TO GET LOUDER AS THE CAR SPEED INCREASES. THESE ISSUES ALL TEND TO HAPPEN AT THE SAME TIME. *TR
