Vehicle slams into first gear upon deceleration and "slips" if you take your foot off the gas pedal and then accelerate immediately, as in traffic conditions. When transmission gets in stop and go traffic it will slam into gear before acceleration occurs. Car was at BMW dealer for seven days with all software upgrades that dealer suggested were performed and still same problem. No call backs to date. Spoke with BMW of North America and they referred me back to dealer. Unwilling to admit there is a problem with the transmission even though they have issued intercompany tech. Bulletins regarding the exact problem.

I have a BMW 750li sedan. The transmission in this car intermittently but approximately 1 time per month has a violent downshift into a low gear. It feels like you have just been rear ended by another car and it is possible to get a neck injury from this "violent" slamming. It happens to other owners of this car as I have read about it on many forums. BMW won't do anything about it if you can not replicate the problem. It seems to happen most often when you are traveling at slow speeds going up a steep hill and you take you foot off the accelerator and then start to accelerate. It is unnerving and dangerous especially if you have passengers in the car.

When driving at low speeds and then lightly accelerating, vehicle slams into a lower gear causing my head to snap back. I have experienced this three times in the past 3 months. The dealer cannot replicate this issue at is random, but other BMW owners have noted the same issue.

The contact owns a BMW 750 li. He lives on a near a cliff and when he parks his vehicle on an incline the vehicle lurches forward. This happens consistently 20 seconds after parking the vehicle and engaging the emergency brake. He first noticed the failure, approximately in February 2007, after parking on an incline. The degree of the incline is not relevant to the failure, even a slight incline will produce the failure, but a large incline will jolt the vehicle forward more violently. The weather was not a factor in the failure. He was told by the service dealer that all BMW 750S perform in this manner and he has that statement written on a service order. The failure mileage was 1300 and the current mileage was 22156. If necessary, please contact the owner via email.
