The Mercedes 722.9 Conductor Plate, a vital component of the 7G-Tronic transmission, often fails, leading to costly repairs. This article discusses common symptoms, the innovative repair service offered by Circuit Board Medics, and why it eliminates the need for programming or SCN coding, saving you time and money.
Understanding the Mercedes 722.9 Conductor Plate
The conductor plate, also known as the Transmission Control Module (TCM) or VGS (Valve Body Control Unit), is the brain of the 722.9 transmission found in many Mercedes-Benz vehicles from 2004 onwards. It controls the shifting process and ensures smooth operation. When the conductor plate malfunctions, it can lead to various driving issues. Our repair service addresses the root cause of these issues, providing a reliable and cost-effective solution.
Common Symptoms of a Faulty 722.9 Conductor Plate
A failing conductor plate can manifest in various ways, often triggering limp mode and storing specific error codes related to speed sensors within the transmission. Common symptoms include:
- Limp Mode: The vehicle enters a failsafe mode, limiting speed and gear selection to protect the transmission.
- Rough Shifting: Jerky or delayed gear changes, making driving uncomfortable and potentially damaging the transmission.
- Transmission Errors: Dashboard warning lights illuminate, indicating transmission problems.
- Speed Sensor Errors: Diagnostic trouble codes (DTCs) specifically related to turbine (Y3/8N1), internal (Y3/8N2), and output (Y3/8N3) speed sensors often indicate a conductor plate issue. Examples include codes P2200, P2201, P2204, P2205, P2206, P2207, and others.
