Do transmissions have to be programmed?
Does the computer have to be programmed if a used transmission is installed? No, it shouldn’t have to be reprogrammed. Sounds like you may have a mechanical concern with your used transmission.
What is the working of the transmission valve body?
Working of transmission valve body. An automatic transmission system has a valve body, which serves as the main control center. The valve body has numerous passages and channels within the valve body.
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.
What are the different types of valve bodies?
For example, the valve body has a 2-3 shift valve which is responsible for up shifting from 2nd gear to 3rd gear. And if there’s going to be a downshift from 4th gear to 3rd gear, then the 4-3 shift valve would be responsible for that. There are two main types of valve body.
Can a reprogramming of the TCU fix a valve body?
Reprogramming of the Transmission Control Unit (TCU) with the latest software is unlikely to permanently fix valve body or conductor plate issues. It could make gear changes smoother for those who are not experiencing transmission problems but should not be seen as a solution when the failure is due to hardware.
When do you need a new transmission valve body?
If one of these solenoids were to fail, you may find yourself locked out of certain gears, or you may be unable to shift at all. A qualified transmission shop may be able to replace a single component inside the valve body, or you may need a new valve body depending on what the root cause of the problem is.

Can you change serial number on valve body?
I’ve not run into a valve body that was tagged before, but since they are now electronic parts too, it only makes sense. The problem for you is that it limits your repair options. The dealers have proprietary software to enable them to change serial numbers on parts, but that software is often slow to make it to the independent market.
