Mercedes 722.9 TCM Speed Sensor Replacement
Send-in speed sensor replacement for your existing Mercedes 722.9 / 7G-Tronic conductor plate (TCM/VGS). This is a repair service for your module, not a replacement module for sale.
All three speed sensors included — $400 USD
- Y3/8n1 — input/turbine speed sensor.
- Y3/8n2 — internal speed sensor.
- Y3/8n3 — output speed sensor at the outer edge of the plate.
All three speed sensors are replaced as standard. No upgrade selection is required. Shipping and any applicable taxes are additional.
Confirm compatibility
Before ordering, contact us with your vehicle year and model, the TCM part number or a clear photo of its label, and the exact diagnostic fault codes. Compatibility and repairability must be confirmed for your particular module. This listing does not cover 722.6, 722.8, VGS2-FDCT, or 725.0 transmissions.
What to send
Send your original electronic conductor plate/TCM only after receiving shipping instructions. Do not send the hydraulic valve body or solenoids. Have a qualified technician remove and reinstall the module. Drain residual fluid, protect the connector and sensor posts, and package the plate securely.
Scope of service
The service covers replacement of all three speed sensors. It does not include a replacement TCM, donor-module cloning or programming, range-sensor repair, solenoids, hydraulic valve-body work, or vehicle removal and installation. Other faults or prior damage may require separate evaluation. Fault codes alone do not establish that a sensor is defective.
Shipping from Canada
This is a send-in service. You arrange and pay for shipping your original conductor plate/TCM to us using your own inbound shipping label. We do not provide a prepaid label for the Canada-to-U.S. shipment.
The shipping charge at checkout covers return shipping back to you in Canada only, using the same services and prices as our ESL service: FedEx 4–5 Business Days — $55 USD; DHL Express 1–3 Business Days — $60 USD; or FedEx Overnight — One Business Day — $75 USD. Carrier transit times exclude repair time and customs delays.
Contact us before shipping for packing and shipping instructions. Confirm any customs paperwork and applicable carrier or import charges before sending your module. All prices are in USD.
