Do you need valve body and conductor plate replaced?
The majority of these transmissions were identified as VGS1 and required the replacement of both the valve body and conductor plate. Unfortunately, Mercedes-Benz declined to sell replacement valve bodies to independent repair shops claiming that these components were related to the security of the vehicle. Yet they will sell complete transmissions.
Do you need to replace the conductor plate on a Mercedes?
If you scan your Mercedes-Benz with a diagnostic scanner you may get several error codes that point you to speed sensor faults. You can not replace the speed sensors themselves and therfore you need to replace the whole conductor plate. Luckily, the transmission does not need to be removed in order for you to replace the conductor plate.
When to replace Mercedes 722.9 valve body and conductor plate?
If these parts fail they will require replacement in order to extend the life of the transmission. The early 722.9 transmissions installed on Mercedes-Benz models between 2004-2008 had a higher failure rate. The majority of these transmissions were identified as VGS1 and required the replacement of both the valve body and conductor plate.
When does a Mercedes Benz transmission go into limp mode?
Diagnose the transmission as soon as possible. While these are the typical symptoms of a failed valve body or conductor plate, Mercedes-Benz transmission can go into LIMP MODE due to other issues that may not be directly related to the transmission. These transmission problems may start developing as early as 50,000 miles.

What causes the conductor plate to malfunction?
The Conductor Plate is a component of the transmission that eventually will malfunction as the vehicle ages. Sometimes the speed sensor built within the Conductor Plate fails causing erratic shifting, in other cases the float may fail causing…
Is the transfer plate part of the valve body?
The valve body separator and transfer plates are considered part of the valve body. They prevent flow in some passages while allowing flow into others. An automatic transmission contains many passages. Most are located in the valve body. The separator plate contains holes or orifices that form a seat for ball check valves.
When to replace or rebuild a transmission valve body?
Rebuilding vs. Replacing the Valve Body The valve bodyis a part of all automatic transmissions that acts as the main control centerof the system. When a failing valve body causes symptoms and/or failures like noise during gear shifts, slippage, delays, and difficulty reversing, a driver is left with no choice but to fix or replace the part.
How much does it cost to replace a valve in a Mercedes?
These transmission problems may start developing as early as 50,000 miles. Having to replace the valve body will cost between $2,000 and $3,000. Reprogramming of the Transmission Control Unit (TCU) with the latest software is unlikely to permanently fix valve body or conductor plate issues.
