    Drain the ATF completely, disconnect all wiring harnesses, cooler lines, and carefully unbolt the existing gearbox to prevent damage to surrounding components.

    Install Reconditioned 7229321

    Position the refurbished transmission using a transmission jack. Replace old seals, torque all mountings according to OEM specifications, and ensure proper alignment with the engine.

    Reconnect Components

    Reconnect wiring, sensors, and TCU connections. Verify that all plugs are fully seated to avoid diagnostic errors and ensure reliable communication between modules.

    Refill ATF Fluid

    Refill with Mercedes-approved ATF 236.15 and adjust fluid levels according to operating temperature guidelines for consistent hydraulic performance.

    Programming & Adaptation

    Perform TCU adaptation and ECU calibration using a Mercedes-compatible diagnostic scanner. This step ensures smooth 7-speed operation, correct gear ratio control, and optimized shift logic.
