A0002701852 722.9 Intelligent Servo Module for Mercedes-Benz

The A0002701852 Intelligent Servo Module is a shift-control component for Mercedes-Benz 722.9 transmission applications. The full module number identifies the part for replacement enquiries.

Compare the original module label, connector and mounting arrangement. Include the vehicle identification and programming requirements so the workshop can plan module installation and setup.

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

The A0002701852 is an Intelligent Servo Module (ISM) that controls gear selection inside the Mercedes-Benz 722.9 (7G-Tronic) seven-speed automatic transmission. The module receives a shift request from the transmission control unit and moves the selector mechanism to engage the commanded gear, which is why it is also described as an electrohydraulic shift actuator rather than a full transmission controller. The A0002701852 carries the electronic servo function only; the gearbox hydraulic control and clutch actuation are handled by the valve body and the transmission control unit, so the ISM is a targeted replacement for shift faults rather than a whole-gearbox fix.

• Component: Intelligent Servo Module (ISM) — shift control for the 722.9 transmission
• Mounting position: installed on the transmission as the electrohydraulic gear selector
• Reference number: A0002701852, matched to the 722.9 transmission family
• Role in the system: converts an electronic shift command into a mechanical selector movement

The A0002701852 Intelligent Servo Module is specified for Mercedes-Benz vehicles running the 722.9 seven-speed automatic transmission. Because the same transmission family was fitted across a wide range of Mercedes-Benz models and production years, the reliable way to confirm fitment is to match the reference number stamped on the original ISM, not the model name alone. Two vehicles of the same model can carry different transmission hardware, so a model-name-only order is the most common reason for receiving a part that does not match.

• Transmission family to match: 722.9
• Primary check: the reference number on the original module label
• Secondary checks: connector pattern and mounting arrangement against your original unit
• Workshop planning: include VIN and any coding or programming requirements in the enquiry

The A0002701852 Intelligent Servo Module is supplied as a new component. TOSEN handles transmission electronics through a factory-direct supply chain and inspects units before dispatch so that the part presented for installation matches the reference number and connector arrangement described here. Buyers who work with export volumes can request samples for qualification before committing to a larger order.

What vehicles use the A0002701852 Intelligent Servo Module?

The A0002701852 Intelligent Servo Module is used in Mercedes-Benz vehicles fitted with the 722.9 seven-speed automatic transmission. Because that transmission was fitted to many models and model years, you should confirm compatibility by matching the A0002701852 reference number on your original module rather than by the vehicle model name alone.

What is the difference between an ISM and a transmission control unit?

The Intelligent Servo Module is the electrohydraulic shift actuator that physically selects gears, while the transmission control unit is the electronic brain that decides when to shift. On the Mercedes-Benz 722.9 transmission these are separate components, so a shift fault traced to the servo module is repaired by replacing the ISM rather than the control unit.

How do I verify the correct ISM before ordering?

First read the reference number printed on the original Intelligent Servo Module and check that it matches A0002701852 for a 722.9 transmission. Then compare the connector and mounting arrangement, and send TOSEN the module label, vehicle VIN and transmission code so the part can be confirmed before you commit to the order.

Does the A0002701852 require programming after installation?

The Intelligent Servo Module is an electromechanical shift component, but the surrounding 722.9 transmission electronics may require coding or adaptation after fitting. Include your workshop’s coding and programming requirements in the enquiry so TOSEN can confirm the scope of work before the module is dispatched.
