Typically a TCM failure is the result of the loss of one or more speed sensor signals. We can repair any version of the 722.9 TCM to help you avoid the high cost of replacement parts and programming. You can still purchase the TCM only for VGS2 and VGS3 versions. This is a significant cost increase over just buying the TCM. For the VGS1 version, you MUST purchase the conductor plate AND the valve body, if buying new. The major difference for the consumer in the three occurs when you try to purchase a new TCM. The next two versions followed and are identified as VGS2 or VGS3. The first generation TCM is the VGS or VGS1 and typically ran from model years 2004-2007. You can identify which TCM you have by the label/engraving on the main plate of the TCM for your vehicle. Overall, the differences between the three are subtle, and the failure modes are similar. There are three different versions of the TCMs in the 722.9 transmissions commonly identified as VGS1, VGS2, and VGS3. Fortunately, we have developed a Mercedes-Benz 722.9 Conductor Plate TCM Repair solution for your original TCM that resolves all of these issues with a fast, one-business-day turnaround. Lastly, the replacement costs for parts, labor and programming for this issue can range from $2,000-$4,000, depending on the type of TCM your vehicle is running. The new TCM still needs to be "married" to the vehicle, which requires SCN coding/programming abilities that most individuals do not have access. Secondly, a replacement TCM is not "plug and play" on the vehicle. First, Mercedes-Benz classifies this Conductor Plate (TCM) as a "theft-related part," making it difficult to purchase as an individual or small shop.

While providing improvements in overall shift comfort and driver experience throughout the gear set, they are unfortunately prone to failure, specifically in the speed sensors on the Conductor Plate / Transmission Control Module (TCM).įor the consumer or independent automotive shop, this failure can be a significant event for several reasons. The 722.9 (7G Tronic) transmission is Mercedes-Benz's 5th generation automatic transmission with 7 forward and 2 reversing gears first introduced in 2004.
