2011 - 2015: 6-speed A6MF2 automatic (2.4L/3.5L) 2016 - 2020: 6-speed A6MF2 or 8-speed A8TR1 (2.0T/3.3L) 2021+: 8-speed A8TR1 (2.5L) or 8DCT (2.5T) or 6-speed (Hybrid)
A6MF2: solenoid pack replacement resolves most cases. A8TR1 shudder: fluid exchange first. 8DCT: PCM update then clutch assessment.
SP-IV ATF (A6MF2) or SP-IV-M (8DCT)
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.
2 - 4 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.
On a 2011 - 2020 with A6MF2, very likely. P0750 - P0760 codes confirm it. Solenoid pack replacement is $550 - 850.
Yes - the A6MF2 and A8TR1 are shared across Hyundai/Kia platforms. Identical repair procedures.
2 - 4 days.
SP-IV for the 6-speed; SP-IV-M for the 8DCT.
The wet 8DCT is more durable than Hyundai/Kia's previous dry DCT. Regular fluid changes are critical.
Same-day appointments available. Honest estimates, no surprises. We've been doing this since 1987.
