Transmission Slip Out Of Gear problems of the 2004 BMW M3

Vehicle drops out of gear randomly. As I was taking a left turn, the vehicle dropped into 0 gear and on coming traffic almost ran into me head on. I had no way of moving the car due to transmission being shifted into neutral. This is due to a defective temperature sensor on the smg pump. BMW ignores the issue.

The contact owns a 2004 BMW M3 convertible. The contact stated that the vehicle would slip out of gear while driving at any speed. The contact stated that because the vehicle had a smg transmission, the failure would not allow the contact to accelerate and he would have to shut the vehicle off and restart to allow the gear to re-engage. The vehicle was taken to the dealer yet he was unable to diagnose the failure. The vehicle was not repaired. The failure mileage and current mileage was 40,000.
