722.9 Speed Sensor and Valve Body Repair

Repair - 722.9 Speed Sensor and Valve Body

NB You cannot DIY this job as flashing of Transmission Electric Control Module requires using a new Software Calibration Number (SCN) and entering the new SCN coding number into the ETC with SDS.

Fortunately several companies specialize in re-manufacturing your Mercedes-Benz 7 speed transmission Valve Body TCU/EHS/7Gtronic Speed sensor plate and provide a 1 year warranty on all speed sensors. Most units are re-manufactured within 24 hours, this includes re-engineering of all the original speed sensors circuitry to prevent repeat failure. They also include a before and after test on a purpose built speed sensor simulator to ensure your unit is re-manufactured to the highest standard. As long as they re-manufacture your unit, there is no need for the additional cost of SCN coding or adaptation.
