722.9 7G-Tronic Transmission Conductor Plate for Mercedes-Benz

This conductor-plate product is for Mercedes-Benz 722.9 7G-Tronic transmission applications. Controller generation and the original part label are essential selection details.

Supply the complete Mercedes-Benz module number and VGS identification. The workshop should plan the programming and adaptation procedure appropriate to the vehicle and replacement controller.

Send the original module label, vehicle VIN, transmission code and required quantity. Include the workshop’s coding or programming requirements in the enquiry.

The 722.9 conductor plate is an electrohydraulic control component for the Mercedes-Benz 722.9 (7G-Tronic) seven-speed automatic transmission. The plate carries the electrical and hydraulic interface between the transmission control unit and the valve body: it houses the speed sensors and the connector that feeds transmission data to the controller, and it provides the conductor paths that link the controller to the shift solenoids and pressure regulators mounted on the hydraulic unit. A conductor-plate fault typically shows up as interrupted or implausible speed signals and disturbed shift quality, which is why the assembly is a common repair item on this gearbox family. Because the plate sits inside the valve body assembly, it is replaced together with the associated seals and, where required, the transmission fluid service.

• Component: Conductor plate / control module for the 722.9 transmission
• Transmission family: 722.9 / 7G-Tronic
• Vehicle application: Mercedes-Benz
• Role in the system: carries the electrical and hydraulic interface between the transmission control unit and the valve body, including speed sensing and solenoid conductor paths

The 722.9 conductor plate is specified for Mercedes-Benz vehicles running the 722.9 seven-speed automatic transmission, also known as 7G-Tronic. The transmission was fitted across a wide range of Mercedes-Benz models and production years, and the valve body and conductor-plate hardware changed over that run, so two vehicles that share a model name can carry different control hardware. Confirm fitment by matching the complete Mercedes-Benz part number on the original component and the VGS identification, rather than by model name alone. The controller generation and the electrical connector layout should be compared against the removed unit before ordering, and the wiring configuration should be confirmed if the transmission is being repaired as a mechatronic assembly.

• Transmission family to match: 722.9 / 7G-Tronic
• Transmission type to match: seven-speed automatic
• Primary check: the complete Mercedes-Benz module number on the original component
• Secondary checks: VGS identification, connector layout and controller generation against your original unit
• Workshop planning: include the vehicle VIN and the required programming or adaptation procedure in the enquiry

The 722.9 conductor plate is supplied as a new component. TOSEN sources 7G-Tronic control hardware through a factory-direct supply channel and checks each assembly against the part number, connector arrangement and the sensor and solenoid interface described on this page before dispatch. Repair workshops and distributors can request a sample unit so that the hardware version is confirmed against the original before a larger order is placed, and the accompanying valve-body requirements can be specified separately in the enquiry so that the supply scope is clear.

Which Mercedes-Benz transmission does the 722.9 conductor plate fit?

The conductor plate fits the Mercedes-Benz 722.9 seven-speed automatic transmission, marketed as 7G-Tronic. Because that transmission was fitted to many Mercedes-Benz models over a long production run, you should confirm compatibility by matching the complete Mercedes-Benz module number and the VGS identification on your original component rather than by vehicle model name alone.

What symptoms point to a faulty conductor plate on a 722.9 gearbox?

A failing conductor plate on the 722.9 transmission commonly produces interrupted or implausible speed signals, disturbed shift quality and stored transmission fault codes, because the plate carries the speed sensors and the conductor paths that link the control unit to the shift solenoids. A diagnostic scan that isolates a speed-signal or solenoid-circuit fault should be completed before the plate is replaced, so that the fault is confirmed to be on the control interface.

Is the conductor plate replaced together with the valve body?

The conductor plate sits inside the valve body assembly on the 722.9 transmission, so replacing it involves opening the hydraulic unit and renewing the associated seals, and the transmission fluid service is normally planned at the same time. For a mechatronic repair, include the controller and wiring configuration in the enquiry so that the hydraulic and electronic components can be matched together.

How do I confirm the correct 722.9 conductor plate before ordering?

First read the part number on the original conductor plate and confirm it corresponds to the 722.9 transmission fitted to the vehicle. Then compare the connector layout, the controller generation and the VGS identification against the removed unit, and supply TOSEN with the component label and vehicle details so the assembly can be verified before you commit to the order.
