2009–2014: 6-speed automatic (A6MF1/A6LF2) standard; 8-speed automatic available on V8 models; rear-wheel drive configuration 2015–2016: 8-speed automatic (A8TR1) on all trims; paddleshift manual mode; updated torque converter clutch calibration Note: Genesis brand spun off as separate marque in 2017 — see Genesis G80 for later models
Diagnosis begins with a full scan for transmission and drivetrain codes, followed by a torque converter lock-up test under load. Fluid condition and level are checked — burnt ATF is a strong indicator of internal damage. Valve body solenoids are resistance-tested. If shudder is present, a torque converter flush with new Hyundai SP-IV ATF often resolves mild cases. Persistent shudder requires torque converter replacement. Valve body replacement covers most solenoid-related shift complaints. Full rebuild is reserved for units with internal clutch pack wear confirmed by pressure testing.
Hyundai SP-IV-M ATF (Genuine or approved equivalent); approximately 8.5 quarts for drain-and-fill; 10 quarts for full flush; do not substitute Dexron VI without confirming compatibility
Fluid service: same day; solenoid or valve body repair: 1–2 days; torque converter replacement: 2–3 days; full rebuild: 4–6 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."

"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."
This is typically torque converter clutch shudder — the lock-up clutch inside the torque converter slips at partial load. A fluid flush with fresh SP-IV-M ATF and a friction modifier additive often resolves mild cases. If shudder persists, the converter itself needs replacement.
Every 30,000–45,000 miles for city driving or towing. Hyundai lists it as 'lifetime' fluid in some manuals, but that is based on ideal conditions — Chicago stop-and-go heat degrades fluid faster.
Sometimes. Hyundai released several TCM calibration updates that improved shift feel on 2009–2013 models. A dealer or shop with the right scan tool can check whether your software is current.
Generally yes — the A8TR1 8-speed had fewer widespread complaints than the earlier 6-speed. The main vulnerabilities are solenoid wear and fluid contamination, both of which are preventable with regular service.
