7DCT: software update first (Hyundai extended coverage to 10yr/100k on some VINs). Mechanical clutch pack rebuild if judder persists after update. A6MF2: solenoid pack replacement or full rebuild. 8DCT (2020+): fluid service first.
7DCT: Hyundai/Kia DCT fluid SP-IV-M A6MF2: SP-IV ATF 8DCT: SP-IV-M
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.
DCT rebuild: 3 - 4 days. 6AT rebuild: 2 - 3 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.

Many are - Hyundai extended powertrain coverage on the 7DCT to 10 years/100,000 miles. Check your VIN at a Hyundai dealer before paying out of pocket.
