  • Supported: Continental Units (found only in F01/F02 and later 6HP models).
  • NOT Supported: Bosch-made TCMs.

Please verify your manufacturer before shipping. If you are unsure, contact us with your VIN or a photo of the TCM housing.

Fault Codes & Error Messages

Common BMW Transmission Error Codes:

  • 400625 – Turbine speed sensor: Value too small
  • 400626 (P0716, P0715) – Turbine speed sensor, short circuit to ground or open circuit
  • 400372 – Ratio monitoring gearshift 5-4 implausible
  • 4F83 – Ratio monitoring clutch C
  • 420636 – Position sensor: Electrical fault L4 Shifter

Important Note: If you are experiencing clutch C codes or solenoid-related codes, this service will not resolve the issue. Please contact our support team for assistance in finding the right service for your needs.

The "Complete Rebuild" Advantage

We don't just "patch" a single fault. Our experience shows that while the Turbine Speed Sensor (Input Speed) often triggers the initial code, the Hall Sensors (controlling gear shifting logic) are equally vulnerable to heat-related failure over time.

Our Process: We address both the Turbine and Hall sensors in a single rebuild cycle, refreshing the entire sensor array to prevent future teardowns.

Important: Diagnostic Disclaimer & Mechanic Responsibility

Please read carefully before ordering. Our service is a rebuilding service, not a diagnostic or testing service.

  • The Rebuild: We install a high-quality rebuild kit featuring new, commonly vulnerable components and ship your module back to you.
  • Diagnostic Reality: Fault codes associated with speed sensors (such as 400625, 400626, or 400636) can also be caused by internal transmission clutch wear, mechanical debris, wiring harness issues, or other vehicle-side faults.
  • Mechanic Responsibility: It is the sole responsibility of the installing mechanic or technician to perform proper troubleshooting and rule out all other mechanical or electrical components before concluding the TCM is at fault.
  • No Testing Provided: We do not test, bench-run, or diagnose your specific TCM. We simply perform the professional installation of the rebuild components.
  • Warranty: 6 months warranty. Our warranty covers the specific components we install and our labor. It does not guarantee that the rebuild will fix your vehicle's specific issue if the root cause is mechanical or external to the TCM.

Output Speed Sensor Notice

Output Speed Sensor fault codes cannot be addressed through this rebuilding service.

The Solution: If you have an Output Speed Sensor failure, we stock Genuine OEM units. We can provide a replacement unit and program it to your VIN for a plug&play solution. Please contact us prior to ordering if you have an Output Speed Sensor code.
