2003–2009: Mercedes 722.6 5G-Tronic (W211) 2010–2016: Mercedes 722.9 7G-Tronic (W212) 2017–2023: Mercedes 9G-Tronic (W213) 2024+: 9G-Tronic continued
Same approach as C-Class. 722.9 conductor plate: targeted repair if clutches are healthy. 722.6: solenoid or valve body rebuild. E63 AMG: TCC and conductor plate addressed together.
MB 236.12 (722.6) or MB 236.14 (722.9) — change every 40,000 miles
Conductor plate: 1–2 days. Rebuild: 3–5 days.
"Honest diagnosis, fair price, and the repair was done right. Chicago Transmission has been my go-to for years. Wouldn't trust anyone else with my car."
"The free diagnostic alone was worth the trip. They found the problem fast, gave me a written estimate, and completed the work on time. Exceptional service."
"Family owned and it shows. They treated my car like it was their own. The lifetime warranty on my rebuild gives me total peace of mind. Highly recommend."
That pattern almost certainly means the conductor plate — not three separate solenoid failures. One repair, not three.
Absolutely — E350 W212 sedans hold value and are well-built. A rebuilt transmission with lifetime warranty is money well spent.
Outside warranty, no. We rebuild E63 AMG transmissions — the 722.9 in AMG applications is the same unit, more heavily stressed.
3–5 days depending on parts availability.
The 9G-Tronic is newer — valve body solenoid wear is the emerging failure mode as these accumulate miles. Fluid changes are critical.
Same-day appointments available. Honest estimates, no surprises. We've been doing this since 1987.
