Mercedes Transmission Conductor Plate Problem. When it comes to Mercedes, there are no “Small” transmission problems? All issues with your Mercedes transmission manual or automatic, need to be addressed, continuing to drive with a problematic transmission can quickly cause major problems that may result in a costly transmission replacement.

Mercedes Transmission Conductor Plate Problem


Now if your Mercedes transmission is running properly, it delivers power seamlessly and effortlessly in every driving condition. As with all transmission, however, problems can creep up to make driving difficult or impossible. At the first sign of a transmission problem, it’s compulsory to visit a qualified shop for inspection, diagnosis, and service to avoid breaking down.

Mercedes Transmission Conductor Plate Problem

The transmission conductor plate is a part of the transmission system. The plate is mounted on the valve body of your automatic transmission. The pressure relief valves, shift control valves, shift control valves, and speed sensors are mounted on the plate. The conductor transmits the signals to the valves from the control module. The sensors mounted on the plate are crucial to the operation of the automatic transmission.

If the sensors fail, the transmission control unit will be unable to determine which gear to enable the transmission in. This will cause the transmission to get stuck in one gear or slip into “limp” mode. While replacing your conductor plate, you should also replace the transmission fluid, gaskets, 0-rings, seals, and pan. Now if you notice that your transmission is not switching gears smoothly, then it is a possible symptom of a failed or damaged transmission conductor.

Symptoms of Failed Valve Body and Conductor Plate

Now if the valve body or conductor plate fails there are some symptoms or signs you will experience. And below are some of them.

  • Check engine light is on.
  • Jolting while changing gears.
  • Engine RPMs are high but the car doesn’t move.
  • Erratic shifting of gears.
  • Transmission stuck in second gear. Limp Home Mode.
  • Shifts from first to second gear then it stays in that gear.
  • Can not drive at speeds over 40 mph.

If you experience any of these symptoms above, you should endeavour to seek help from a qualified auto technician. delaying the visit to the repair shop will only compound a problem that would have otherwise might have been easy to replace.

Causes of Transmission Body Valve Failure

Below are some of the causes of failure in the transmission valve body

  • Lack of lubrication: you should have in mind that the transmission valve body is built up with many components that are made of metal, proper lubrication is important. This lubrication is mainly vital for moving parts such as the valves that open and close to allow hydraulic fluid to go through them. Now if the lubricant is worn out or leaks out, the metal parts of the transmission valve body rub against each other and wear out.
  • Fluid contamination: the transmission fluid is also required to be absolutely clean and at a very specific pressure. When the fluid comes in contact with dust particles, for instance, the pressure is affected due to the loss of viscosity of the fluid. Once the pressure is affected then the whole transmission system is compromised because it works based on the transfer of pressure throughout the system.
  • Overall wear and tear of parts: This Is the major cause of many car problems in general. The more the moving parts a component has the more likely it is to become worn out and break down. The transmission valve system has different components all of which can be affected by age and cause problems in the overall functions of the valve body.

Above are some of the causes of failure in the transmission valve body.
