2011 - present: RE7R01A 7-speed automatic (5.6L V8)
Same as Q50 but with V8 torque considerations. Solenoid pack + converter inspection simultaneously. Full rebuild with heavy-duty clutch pack consideration for towing-use QX80s.
Nissan Matic-W - change every 25,000 miles for towing use
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.
Solenoid: 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.
Yes - slip under load is urgent. Stop towing until diagnosed. Continuing to tow with a slipping transmission causes catastrophic failure.
Every 25,000 miles minimum. The 5.6L V8 plus towing load is hard on Matic-W fluid.
QX80s hold significant value. A rebuild with 2-year / 24,000-mile warranty is the right investment.
3 - 5 days.
The RE7R01A family is related. The QX80 is tuned differently for its AWD application.
