Beckmann Technologies has the answers to your transmission module questions and the parts your customers need.

Transmission Control Modules (TCM)

The Mercedes 722.6 transmission is no stranger to problems. One of the common components of the system to fail is actually outside of the transmission and is often overlooked until it is too late. If you don't already know, we are talking about the EGS51, or transmission control module (TCM). Often mounted in the module case of the engine bay, they commonly fail due to transmission fluid “leaking up” the harness over time and into the unit case. This common issue is no problem for Beckmann Technologies to fix.

Becktech is able to repair and return your EGS51 and the TCM comes pre-programmed to your VIN.

How do you determine the proper coding for my car and control unit?

All we need is your VIN and the TCM part number directly from your vehicle, and we can determine the appropriate coding for your unit.

What do I need to do when I install a replacement module?

Newly installed TCM's require a quick learning/adaptation procedure. Instructions are included with each module but it is nearly as simple as installing it and driving it very easy in each gear before regular use.

Can I just use a used unit since these came on so many cars? Aren't they all the same?

No. Using a used TCM/EGS can cause more problems than it solves. While it is true that the manufacturer equipped many of their vehicles with the 722.6 transmission, each chassis number has its own set of part numbers and codings that are crucial for proper operation.
