Mercedes 9G-Tronic 725.0 TCM Repair Service

If your Mercedes-Benz 9G-Tronic 9-speed automatic transmission is acting up, you've come to the right place. At ECU Maverick, we specialize in repairing the 725.0 VGS-NAG3 transmission control module. No dealer programming needed — this is a plug-and-play fix. Ship us your unit and we'll return it within 24–48 hours, ready to install.

Common Symptoms of a Failing 725.0 TCM

Is your Mercedes giving you a rough ride? Below are the most common signs that your 725.0 transmission control module may need repair. Ship your TCM without the valve body — we handle the rest.

  • Harsh or Erratic Shifting — The vehicle jerks or shudders during gear changes, indicating abnormal shift logic from the TCM.
  • Slipping Gears — The transmission drops out of gear, causing a sudden loss of power and acceleration.
  • Delayed Engagement — Noticeable lag when shifting from Park to Drive or Reverse.
  • Warning Lights — Check engine light or transmission malfunction indicator illuminates on the dashboard.
  • Reduced Performance — Sluggish acceleration or the vehicle entering limp mode (locked in a single gear).
  • Unusual Noises — Grinding or whining sounds originating from the transmission area.
  • Stalling — In severe cases, the vehicle may stall or struggle to maintain forward motion.

Diagnostic Trouble Codes (DTCs) We Repair

If your mechanic has pulled codes from the transmission control module, here are the fault codes most commonly associated with 725.0 TCM failures:

Frequently Seen Fault Codes

  • P073E00 — Reverse gear cannot be engaged (stored)
  • P07B700 — Pressure sensor signal is implausible (undefined)
  • P07B7-00 — Park pawl Sensor A has a sporadic malfunction

These codes point to internal failures within the transmission control module itself. Our repair addresses the root cause so you get a lasting fix — not a temporary reset.

Our Repair Process: Simple, Fast, and Hassle-Free

We take the complexity out of transmission control module repair. Our service is designed for both independent shops and DIY owners who need a reliable, turn-key solution.

How it works: Ship us your 725.0 TCM (without the valve body). We diagnose, repair, and fully test the module, then ship it back programmed and ready to install — no dealer visit required. With our 24–48 hour turnaround, you won't be waiting around.

As part of our repair, we replace the pressure sensor with a brand-new, high-quality replacement part — not a refurbished or salvaged unit. This is one of the most common failure points inside the 725.0 TCM, and installing a new sensor ensures long-term reliability and eliminates recurring P07B700 pressure sensor faults.
