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.

Getting Started

Start a request

Open a request in MavConnect, our customer portal, and tell us the vehicle, the module and what it's doing. A technician reviews it and sends your Technical Review — the price and the shipping instructions — in writing. Accept it, ship the module with any carrier (USPS, FedEx or UPS), and write your request number on the box.

WHAT'S COVERED

A technician looks first

Every request starts with a $195 Technical Review: a technician checks your part number, codes and photos against this service and confirms it's the right call before you ship anything. Go ahead with it and the $195 comes off your price. Want the module measured on the bench before we work on it? Add bench evaluation when you submit — $195 per hour, and you'll know the hours before we start.

WHAT TO EXPECT

Turnaround & warranty

✓ Turnaround: stated in your Technical Review and counted from the day your module reaches our bench.  

✓ Warranty: six months on rebuilds and programmed replacements, when installed by a licensed shop.

✓ Programming: your module comes back with its own programming — plug in and drive. Programmed to your VIN — plug in and drive"

About ECU Maverick — ECU Repair, Rebuilding & Programming Specialists

ECU Maverick rebuilds, programs and clones control modules for European, domestic and specialty vehicles. Based in Fort Myers, Florida, we work with independent shops, dealerships and vehicle owners nationwide — by mail.

Where most shops replace and reprogram, we work at the board level: our technicians rebuild the circuits that fail, bringing back modules others write off. That comes from years of reverse engineering and bench work across thousands of control units.

Plug-and-play ready — Rebuilt modules keep their programming; replacements are programmed to your VIN. No dealer visit.

A technician, in writing — Every answer comes from the technician who has your file, on your request in MavConnect. You can read it twice, share it with your shop, and come back to it a year later.

Six-month warranty — On rebuilds and programmed replacements, when installed by a licensed shop. Full terms on your request.

Our Commitment

We exist to keep your vehicle out of the dealership and back on the road — a technician's honest answer, a price in writing, and the same care we'd give our own car, from the first message to the day the module is back in your hands.
