I purchased a 2007 mercedes benz c230 sport from a private seller. I soon learned that the vehicle was in limp mode. The dealer said it was the transmission conductor plate. After hours of research, I discovered several owners of a mercedes with the 772.9 transmission have been experiencing the same issue. I ended up paying $2500 for a new tcu from mercedes benz.

At 115,000 miles the vehicle started experiencing issues shifting from park to reverse or drive. Once in reverse or drive, it won't shift back into park. The car must be turned off in neutral position or wait up to 5 minutes before shifting back into park. Once engaged in reverse or drive there is no problem with the transmission's operation.

Transmission will not shift, goes into limp mode. Turn the car off, wait a couple minutes, restart the car and it drives fine. This first happened may 2015 with 66,000 miles. Our mechanic told us this is a very common mercedes transmission failure. We choose to replace the fluid, and it did seem to help. Now we have 79,500 miles and it goes into limp mode once a week. The fluid was supposed to last 100,000 miles. Our mechanic said the fluid we changed was clean. This is a very dangerous situation, a known mercedes defect with the transmission electronics. The next step if we decide to keep the car is to replace the transmission conductor plate. Never again will I buy a mercedes. This car has been babied by my wife, and has less than 100,000 in 9 years. Any japanese automobile would have easily provided double the life before failure. This is totally unacceptable to be facing thousands of dollars in repairs to a car with on 79,500 miles.

On several occasions I have experienced my vehicle going into limp mode due to the same transmission problem that everyone else seems to be having. It has happened when pulling away from an intersection, trying to overtake a slower vehicle, trying to get up to speed entering the interstate, but nothing particular seems to trigger it. Fortunately, I have always been able to pull the vehicle to the side of the road, shift to park, and shut the vehicle off and restart it, which would fix the problem. Until now. After the last time it happened, the vehicle will not reset. It is stuck in what appears to be second gear. I can't believe that mercedes benz has not been forced to recall the vehicles equipped with the 722.9 transmission. I have researched this on the internet and it appears to be a problem world wide. It has caused accidents resulting in injury and death and it is clearly a safety issue. The problem is caused by a defective transmission control module which is located inside the transmission, on top of the valve body. Mercedes refuses to sell the part to anyone other than mercedes repair shops. My car only has 85,000 miles on it, I bought it used 6 months ago.

The mercedes benz c230 with 69,000 miles has after coming to a stop - I would place foot on accelerator and the vehicle would barely get moving would move slowly and would not shift out of low gear. It would barely move. On other occasions the vehicle would not go and the vehicle RPM's would rev beyond normal RPM's. This could happen also at any speed. I feel that this is a dangerous condition and the following parts have been defective and mercedes is controlling the use of these parts because they know that they have an unsafe design and can prove to be hazardous to drivers.. I went to have the vehicle repaired at a local very reputable third party dealer and mercedes benz would not sell the necessary repair parts to any non mercedes dealer. It is my opinion based on reading about this particular vehicle that the transmission speed sensors have a faulty design as well as the transmission valve body and the hydraulic control unit. I would suggest that this be investigated by the highway safety board and provide for a recall of these items and notify all owners of vehicles. Mercedes benz is aware that they build a unreliable and unsafe power train for this vehicle.

There is a known manufacture defect in the m272 engine. The engine balance shaft sprocket was made of soft metal which causes the drive sprocket to wear prematurely. This wear causes the timing of the engine to become off, which then causes the car to automatically go into limp mode. In limp mode, the car suddenly cannot be driven over 20 MPH and the engine has to be shut off and restarted to exit limp mode. I approached a mercedes benz dealership and the estimate for the repair was over $7,000! This engine defect causes the car to go into limp mode and is very dangerous.

While driving, my car would not shift to the next gear. I pulled over and shifted into park. The car jerked hard. Then I put the car in drive and it jerked hard again. I pulled away and the car had low power and then would not shift passed second gear. I pulled over again and shifted the car to park, turned off the engine, turned it back on and shifted to drive and it worked fine. It's now done this about 15 times while driving at different speeds.

I have a c230 sports sedan with 45,000 miles. The transmission had been sticking in gear, but if I turned the car off and removed the key it would reset and usually be ok for a while. Now it is stuck in first gear, and nothing I have tried has done any good. It will not shift out of first gear. It has an automatic manual transmission but the manual function does not work and even trying to shift manually does no good. This is a common problem with this model and yet mb has never issued a recall. This is pretty clearly a factory defect and needs to be addressed.
