The caller said vehicle seemed to shift into a lower gear when driving between 30 and 40 mph. When this happened vehicle bucked forward. The caller pulled over as soon as she could because she did not know what was causing this problem. It happened 5 times, two time in June, once in July and twice in August. The dealer said not to worry about it. Manufacturer has not been contacted yet.
My transmission would not shift out of second gear. I turned it off and back on and it did not clear. I got a "pre-safe unavailable" message. I did some research and learned this is a "transmission control module" failure. It is very unsafe in that the car cannot keep up with traffic and is a danger to myself and others.
The contact owns a 2006 mercedes-benz S500. While driving 20 mph with the brake pedal depressed, the vehicle jerked before coming to a halt. The failure recurred on numerous occasions. The vehicle was taken to a dealer where it was diagnosed that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 60,000.
