722.9 Transmission Control Module Repair Service

This listing is a repair service for your existing 2004+ Mercedes-Benz 722.9 Transmission Control Module (TCM) conductor plate or VGS. This service is specifically for vehicles equipped with the 7-speed 7G Tronic transmission and aims to eliminate the need for costly programming or SCN coding typically required for replacement modules. Circuit Board Medics provides a repair solution that avoids the dealership fees associated with a new conductor plate. This repair service is compatible with VGS1, VGS2, and VGS3 control modules. It is explicitly stated that this repair is NOT for VGS4 modules. The service is designed to correct specific error codes related to the Turbine Speed Sensor (Y3/8N1), Internal Speed Sensor (Y3/8N2), and Output Speed Sensor (Y3/8N3). These include codes such as 0715, 0716, 0717, 0718, P2204, P2205 for the turbine sensor; 2766, 2767, 2768, P2200, P2201 for the internal sensor; and 0720, 0721, 0722, 0723, P2206, P2207 for the output sensor. It is important to note that false diagnostic codes for the Output Speed Sensor can sometimes be caused by faulty wheel speed sensors. Before sending in your TCM, it is recommended to check ABS and ESP modules for wheel speed sensor codes and inspect wheel speed data. If issues are found, replace affected wheel speed sensors and re-test before removing the TCM. If you are experiencing other error codes not listed, contact Circuit Board Medics for consultation. An optional scan tool rental is available for $50 to clear error codes upon return of the repaired TCM, with an additional $300 charge if the rental tool is not returned. When removing the TCM, take care not to damage the transmission connection plug, as a $50 charge will apply if it is broken. Do not ship the TCM with the valve body or solenoids. The repair comes with a 1-year warranty and 1-business day turnaround time.
