Mercedes Benz transmission bulletin


Did you know there is a Mercedes Benz transmission bulletin regarding potential issues with Mercedes Benz transmission manufactured since 2004? Transmission failure on these cars may be due to problems in a part of the transmission called the conductor plate. The plate in question holds speed sensors that tell the brains of the electronic transmission what gear the transmission is in. These sensors fail and are part of a module called a conductor plate. When they fail the transmission will typically not shift past second gear. This is referred to as “limp home mode.” Just as the name suggests limp home mode is programmed into the transmission so that if there is a failure, even though the transmission is not in a condition for general service the customer can, “limp home,” to a repair facility and the fault can be diagnosed and repaired.

Don’t let any one sell you a Mercedes Benz transmission with out first checking this bulletin. Make an appointment at Master Auto Tech by calling (360) 733-3043 or by going to our website We can find out if your Mercedes Benz my be one of the vehicles effected in as little as thirty minutes.
