Mercedes-Benz 722.9 Transmission Conductor Plate Repair - Plug and Play

Regular maintenance and timely attention to transmission performance can help prevent TCM-related problems. If you experience any symptoms such as erratic shifting or fault codes, it's advisable to seek professional inspection and repair promptly.

When shipping your transmission control module for testing or repair, ensure that you send only the plastic module. Do not include the metal valve body, as this can cause damage during transit.

Fault codes commonly linked to TCM or conductor plate issues include:

• P0705: Component Y3/8S1 (Selection Range Sensor VGS) is defective
• P0717: The signal from component Y3/8N1 (Turbine Speed Sensor VGS) is not available
• P0718: Component Y3/8N1 (Turbine Speed Sensor VGS) is defective
• P0721: The transmission output speed signal is implausible when compared to the wheel RPM signal
• P0722: The signal from component Y3/8N3 (Output Speed Sensor VGS) is not available
• P0723: Output Speed Sensor (VGS) is defective
• P2200: The signal from component Y3/8N2 (Internal Speed Sensor VGS) is not available
• P2201: Component Y3/8N2 (Internal Speed Sensor VGS) is defective
• P2767: The signal from component Y3/8N2 (Internal Speed Sensor VGS) is not available
• P2768: Component Y3/8N2 (Internal Speed Sensor VGS) is defective

The 722.9's Transmission Control Unit (TCU) continuously learns and adapts to the driver's behavior, adjusting shift points and patterns to match driving styles. This ensures optimal performance and a personalized driving experience.

The 7G-Tronic offers:

• Improved Fuel Efficiency: More gears allow the engine to operate in its optimal range.
• Enhanced Acceleration: Closer gear ratios provide smoother and quicker shifts.
• Adaptive Shifting: The transmission control unit learns and adapts to driving styles for personalized performance.

o identify the correct transmission fluid:

• Production Date: Vehicles produced before June 2010 typically use red fluid, while those produced after use blue fluid.
• Transmission Serial Number: Located between the bell housing and transmission pan; serial numbers below 2834527 use red fluid, and those above use blue fluid.
• Transmission Pan: Early models have pans with small dimples, while "Plus" models feature deeper dimples.

The 722.9 conductor plate, also known as the Transmission Control Module (TCM), is an integral component of the 7G-Tronic transmission system. It houses essential sensors and electronics that manage gear shifting and overall transmission performance.

Signs of a malfunctioning conductor plate include:

• Delayed or harsh gear shifts
• Transmission entering limp mode (stuck in a single gear)
• Illumination of the check engine light
• Diagnostic trouble codes related to speed sensors, such as P0717, P0722, and P2200

Our repair service involves refurbishing your existing conductor plate to address any faults. This process eliminates the need for programming or SCN coding upon reinstallation, ensuring a seamless and cost-effective solution.

We offer a standard 3 to 5 business-day turnaround for the repair service.

Yes, our repair service is backed by a 6-month warranty, providing you with peace of mind and assurance of the quality of our work.

No reprogramming or SCN coding is required after our repair. Your existing keys and vehicle settings will function seamlessly upon reinstallation of the repaired conductor plate.

You can begin by placing a testing order on our website. Once we receive your unit, we will proceed to perform a repair on your part.

If the unit is damaged beyond repair, we also have the option to offer you a replacement 722.9 conductor plate.

Yes, we can repair all versions of the 722.9 conductor plate, including VGS1, VGS2, and VGS3 models. Our specialized repair process addresses common failures across these versions.

The version of your conductor plate is typically indicated on the label or engraving on the main plate of the TCM. VGS1 units were commonly used from 2004 to 2007, while VGS2 and VGS3 followed in subsequent years.

The 722.9, also known as the 7G-Tronic, is a seven-speed automatic transmission introduced by Mercedes-Benz in 2003. It features seven forward gears and two reverse gears, enhancing fuel efficiency and acceleration compared to its predecessors.

The 722.9 transmission has been utilized across a wide range of Mercedes-Benz models from 2004 through 2016, including:

• CL500
• CL550
• SLK55 AMG
• CLK500
• E500
• S430
• S500
• CLK55 AMG
• CLS500
• S550
• CLK63 AMG
• CLS63 AMG
• E63 AMG
• CLK550
• E550

Common problems include:

• Conductor Plate Failure: Issues with the transmission control module leading to erratic shifting.
• Valve Body Wear: Causing harsh or delayed gear changes.
• Torque Converter Problems: Leading to shuddering or slipping during acceleration.
• Fluid Leaks: Resulting from worn seals or gaskets.

For early 722.9 models using red transmission fluid, it's recommended to service the transmission every 30,000 miles. For later "Plus" models using blue fluid, the service interval extends to approximately 77,000 miles. Regular maintenance ensures longevity and optimal performance.
