There is a defect in the speed sensor. There is a defect in the actuator. The transmission software is not properly programmed. The datalink does not recognize the transmission type. There are other active transmission faults. Problem Procedure Result Action Check for other MID 130 fault codes. Other fault codes are active. Troubleshoot the other active fault codes. No other fault codes are active. Go to the next step in the table. There is a transmission software problem.
Using the ServiceLink diagnostics template, view the different gear positions, check that the clutch opens and closes, and that the x-y actuator moves from reverse, 1st, and 2nd gears. The x-y actuator responds properly and the fault clears. No further action is needed. The fault is still active. Go to the next step in the table. There is component damage in the transmission. Do a visual inspection of the x-y actuator, the hydraulic system, and the transmission shift system. Damaged components are found. Contact Mercedes-Benz Transmissions Service Support with the AGS codes and results of the electrical pre-test. NOTE:
