When it comes to transmissions it’s important to have any unusual shifting looked after right away. Our diagnostics experts will identify the problem, if any, and take all the steps to avoid major damage that could require a transmission rebuild.

As your Mercedes ages, or if it hasn’t been properly maintained, you may find yourself in “limp home mode.” The Electronic Transmission Control (ETC) module has detected a problem and won’t allow shifting in order to avoid major damage. That’s often just a sensor failure, calling for a straightforward transmission repair. Or it could require a complete transmission rebuild. Our decades-long reputation demonstrates that you can trust is to make an honest appraisal.

Mercedes uses some ten types of transmissions: three-speed (722.0), four-speed (722.1, 722.2, 722.3, 722.4), five-speed overdrive (722.5), six-speed overdrive (722.6), and seven-speed overdrive (722.9). The 722.6 is the most common, and you need to have up to date information regarding its maintenance. Introduced as “sealed for life,” Mercedes now recommends transmission service, including fluid and filter change, every 40,000 miles.

We keep up to date on factory information, and know what to keep an eye out for such as fluid leaks around an electrical connector, hard shifting, and a clunking noise. In particular, 2006 through 2014 E350 Series vehicles with seven-speed transmissions are known to have a specific problem leading to rough shifting. The solution is replacing an internal component with an updated part. Allstate always uses fluids and parts on Mercedes’ approved list.

In extreme cases you’ll need a transmission rebuild, our specialty. That’s not cutting corners. Even at a dealership a replacement transmission is a factory rebuild, not a totally new transmission.
