The engine is responsible for generating power that is used to move the vehicle. In order for that power to be transferred to the wheels, there are tons of other components that need to work properly.
Your transmission system plays a vital part in this power distribution process. By changing the gears of the engine, the transmission helps transfer power to the wheels so the vehicle can build more speed. With so many moving parts and regular exposure to extreme heat, it is only natural for transmission components to wear out over time. If you have an automatic transmission assembly in your vehicle, one part that you should not neglect is the automatic transmission conductor plate.
What is a transmission conductor plate?
The transmission conductor plate is a crucial part of an automatic transmission assembly. It is where several transmission components are mounted, including the pressure relief valves, speed sensors, and shift control valves. The transmission conductor plate can be found on the valve body of the automatic transmission.
How does a transmission conductor plate work?
There are solenoids, valves, and sensors connected to the automatic transmission conductor plate. Once the engine control unit or ECU sends the signals, the automatic transmission conductor plate’s job is to relay them to the devices that are mounted on it. By doing this, the engine control unit receives the important information it needs to keep the engine and vehicle running smoothly.
How long does an automatic transmission conductor plate last?
It depends on the age of the automatic transmission conductor and its mileage. But typically, automatic transmission components are designed to last for 150,000 to 200,000 miles. Of course, driving habits and frequent use can also have an impact on the lifespan of any transmission device like the automatic transmission conductor plate. In extreme cases, it may require replacement after 15,000 miles. If you don’t want more issues appearing in your vehicle’s transmission system, it is recommended to replace the automatic transmission conductor plate when it starts to show signs of failure.
Common automatic transmission conductor plate symptoms
When the automatic transmission conductor plate goes bad, it can affect the whole transmission assembly. Your will vehicle will have trouble shifting gears, which can make driving more difficult for you. Fortunately, you can avoid this problem by immediately replacing your automatic transmission conductor plate when it shows the following symptoms of failure.
Erratic changing of gears
If the automatic transmission conductor plate is failing, it won’t be able to deliver the signals from the engine control unit to the various automatic transmission devices like the shift control valves and speed sensors and vice versa. This could lead to the erratic changing of your vehicle’s gears. It may sometimes seem fine, but there are also times when it won’t shift to any gear at all. Driving with such a problem is definitely annoying. Make sure to fix it by replacing the transmission conductor plate in your automatic transmission assembly.
Gearbox activates limp mode
Once the vehicle’s computer notices that there is a problem in the automatic transmission system, the gearbox can go into limp mode. This means that your car would automatically shift to a lower gear and you might not be able to change to any gear at all. This happens because the speed sensors as well as the other devices mounted on the faulty automatic transmission conductor plate do not respond to the signals sent by the vehicle’s computer. This allows the computer to assume that there is a problem in the transmission. Hence, it forces the gearbox to go into limp mode.
Not selecting gears
Another problem that may occur when your automatic transmission conductor plate is faulty is when the gears can’t be selected properly. You may be trying to reverse and select the right mode, but it may not work. In some cases, you may not be able to drive your car because the gear won’t engage. The only way to fix this problem is to get your automatic transmission conductor plate inspected and replaced if necessary.
Things to consider when choosing an automatic transmission conductor plate replacement
Before purchasing a replacement for your bad automatic transmission conductor plate, there are some things that you need to consider. The following factors can help you make a better decision.
You have to choose a replacement part that is built to last so that you can get the best value for your money. There are also a lot of important transmission devices that are mounted on the automatic transmission conductor plate, so you need it to function properly always. Make sure the part that you are going to get is made from durable materials and can withstand the wear and tear that comes with daily use.
The automatic transmission conductor plate replacement should be able to fit seamlessly with the rest of your automatic transmission components. That’s why it is crucial that you get a unit that is made specifically for the year, make, and model of your vehicle. An automatic transmission conductor plate that fits will save you from having troubles during the installation process.
How much does an automatic transmission conductor plate cost?
The price of a replacement automatic transmission conductor plate is usually around $100 up to $250. Of course, the price may vary depending on your car’s year, make, and model. An aftermarket automatic transmission conductor plate can be purchased per unit or as part of a kit. If you want to protect yourself, be sure to purchase a part that comes with a product warranty.

Does Your Car Have An Automatic Transmission Conductor Plate?
In the 1990s, the German auto manufacturer Mercedes-Benz took a shift from hydraulic automatic transmission to an electronic model. This electronically controlled automatic transmission is called the Mercedes-Benz 5G-Tronic or also known as the 722.6 transmission. It is equipped in countless models under the Daimler-Chrysler wing that were produced in the past two decades. This transmission has features and parts that are exclusively made for it only. One of those is the automatic transmission conductor plate. Here are some things to look into before determining if your ride needs this specific part:
Does your vehicle have a 5-speed automatic transmission?
The conductor plate is designed to work with a 5-speed automatic transmission. This is the first thing you should look out for before you can determine if the part will fit and work with your vehicle. This should fairly easy to identify. Before you purchased your vehicle, you should have already been informed whether it is an automatic. But just to be sure, a vehicle with an automatic transmission should be recognized with its shifter and the absence of the clutch pedal. Likewise, determining whether it is a 4-speed or 5-speed should be spotted on the indicator on the shifter assembly or the instrument panel.
What is the year model of your vehicle?
The conductor plate was first put into use in the Mercedes-Benz W140 series back in 1996. During that time, the 5G-Tronic was one of three transmissions set to go with the engine options available for that model. From there on, it has been integrated into many other vehicles that found good use of that automatic tranny. Interestingly, it is still used in present models affiliated to Mercedes-Benz. So if your vehicle falls under those that were produced from 1996 up to the present, there might be a good chance that you use the conductor plate.
What engine and drivetrain package is your vehicle using?
The 5G-Tronic is a factory option that goes along with certain model packages of different vehicles. Engine compatibility includes some four bangers, V6s, V8s and V12s. This transmission even lent its notable performance to diesel engines.
Because of its high torque capacity, the 5G-Tronic is also paired with the performance blocks such as the V8 AMG Kompressor and the V12 power plant found in the S600 and S65 AMG. However, the engineers in the MB headquarters were able to manufacture a newer transmission capable of doing the same job later on. This is why models after 2014 are not equipped with the 5G-Tronic anymore.
If your vehicle is not Mercedes-Benz, find out if a 5G-Tronic is bolted into its drivetrain.
As mentioned earlier, there are other automotive marques that are benefitting from the 5G-Tronic. These brands are Chrysler, Dodge, Freightliner, Jaguar, Jeep , Maybach, Porsche and Ssangyong. The list of the non-Mercedes models that use this transmission includes the Dodge Challenger, Dodge Charger, Jeep Wrangler, Porsche 911 and Jaguar XK. Just make sure to do a bit more research to make sure that the year model and trims fall under those that are supported by the 5G-Tronic.
