722.6 TCU Transmission Conductor Plate for Mercedes Jeep Dodge Jaguar 1402701161 1402700861

New replacement transmission conductor plate for Mercedes-Benz vehicles equipped with the 722.6 five-speed automatic transmission.

Also known as the 5G-Tronic or NAG1 transmission, the 722.6 uses this electrical conductor plate above the valve body to connect the transmission solenoids and monitor internal speed, temperature, and gear-selection information.

This listing is for the conductor plate only. It is not a complete valve body or transmission control module.

These are transmission-based applications only. Do not order for a non-Mercedes vehicle without confirming that its original conductor plate interchanges with A1402701161.

Important compatibility notes

• The vehicle must have the 722.6 five-speed automatic transmission.

• This part does not fit the Mercedes 722.9 seven-speed transmission.

• Vehicle year and model alone are not sufficient to confirm compatibility.

• Some vehicles were offered with multiple transmissions during the same model year.

• Confirm the transmission identification number before ordering.

• The correct application uses a six-solenoid valve body and the round dipstick-guide conductor plate.

• Some NAG1 applications use a different plate or guide configuration.

Conductor-plate functions

The conductor plate provides the internal electrical connection for the transmission’s six shift and pressure-control solenoids. It also contains or supports signals for:

• Internal transmission speed sensors

• Transmission-fluid temperature

• Park and neutral position detection

• Gear-selection information

• Solenoid operation

Possible failure symptoms

A faulty conductor plate may cause:

• Transmission limp or failsafe mode

• Transmission stuck in second gear

• Harsh, delayed, or erratic shifting

• Failure to upshift or downshift correctly

• Intermittent loss of gear engagement

• Incorrect internal speed-sensor readings

• Transmission warning light

• Speed-sensor or gear-ratio fault codes

Frequently associated diagnostic codes can include P0715, P0717, P0720, P2200, P2203, 0717, and 2767. Codes vary by vehicle and diagnostic system.

These symptoms can also be caused by damaged wiring, a leaking connector sleeve, low or contaminated fluid, faulty solenoids, valve-body wear, or transmission-control-module problems. Proper diagnosis is recommended before replacing parts.

Package contents

• One 722.6 transmission conductor plate

Valve body, solenoids, transmission filter, oil-pan gasket, connector sleeve, electrical harness, transmission fluid, and installation hardware are not included unless specifically shown and stated.

The following numbers identify related service components and should not be presented as conductor-plate interchange numbers:

• 203 540 02 53 — electrical connector sleeve

• 140 277 00 95 — transmission filter

• 140 271 00 80 — transmission oil-pan gasket

Installation

Installation requires draining the transmission fluid, removing the transmission pan and filter, lowering the valve body, and transferring the solenoids to the replacement conductor plate.

Maintain strict cleanliness during installation. Use the correct Mercedes-approved transmission fluid and follow the proper torque specifications and fluid-level procedure.

A bare 722.6 conductor plate normally does not contain vehicle-specific VIN programming. However, stored fault codes may need to be cleared, and transmission adaptations may need to be checked or reset with suitable diagnostic equipment.

Professional installation by a qualified transmission technician is strongly recommended.
