Mercedes 722.8 CVT TCM Repair (VGS / FCVT / Autotronic)
Turbine Speed Sensor & RPM Signal Faults | Full Refurbishment + Bench Test
The Mercedes-Benz 722.8 Autotronic CVT Transmission Control Module (TCM) is a common failure point on A-Class (W169) and B-Class (W245) vehicles. These modules frequently develop internal faults that trigger turbine speed / RPM sensor related codes, intermittent comms issues, limp mode, harsh engagement, or no drive/gear selection concerns.
At Get Electronic, we provide a specialist repair service to fully refurbish the 722.8 TCM. Our process focuses on long-term reliability: we diagnose the root cause and replace known failure components with new parts where required, not just “patch” the fault. The module is then bench tested to confirm stable operation prior to return.

These modules commonly present with speed sensor / RPM signal related faults, including (examples):
P0720 (speed gradient / implausible speed signal)
