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
Verify exact spec on the dipstick label or owner's manual before fill. Recommended change interval: every 60,000 miles for normal driving, 30,000 miles under severe service (towing, stop-and-go, hot climates). Pan service typically takes 6 - 8 quarts; a full fluid exchange takes 10 - 14 quarts depending on cooler-line capacity.
Conductor plate: 1 - 2 days. Rebuild: 3 - 5 days.
Fluid service and inspection complete the same day. Solenoid or sensor replacement: 1 day. Torque converter or seal repair: 2 - 3 days. Full rebuild with road test: 4 - 6 days. Time estimates assume parts in stock - call (312) 626-8759 to verify availability for your specific vehicle.
Every vehicle needs diagnosis before anyone can promise a repair path. These are the situations we help organize before you decide what to do next.
Tell us when it happens, whether reverse still works, and if warning lights are on. A scan and fluid check come before guessing at a rebuild.
Fluid condition, leak location, and driving distance matter. If the vehicle is slipping badly or overheating, towing may be the safer next step.
A failed solenoid, valve body, converter, or internal clutch problem can lead to very different repair paths. The goal is a clear diagnosis and written estimate.
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 2-year / 24,000-mile 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.
