Hyundai Elantra, CN7 (USA)

Additional Notes

• The Hyundai Elantra CN7 (USA) manual transmission fluid specifications cover two distinct engine configurations, the 1.6 T-GDI and the Elantra N 2.0 T-GDI, each with separate capacity and interval figures.
• The 1.6 T-GDI transaxle carries a fluid capacity of 1.5-1.6 liters, which is a typical service fill range for a compact manual transaxle and reflects the volume needed to bring the unit to the correct operating level without a full overhaul drain.
• The Elantra N 2.0 T-GDI transaxle holds a noticeably larger capacity of 1.8-1.9 liters, consistent with a higher-output drivetrain that requires a greater fluid volume to manage heat and lubrication demands under performance conditions.
• The 1.6 T-GDI is assigned a normal use condition, with a change interval of 40,000 miles or 48 months, whichever comes first, meaning the interval accounts for both mileage accumulation and time elapsed under standard driving circumstances.
• The Elantra N 2.0 T-GDI carries a severe use condition designation, with a change interval set at 72,000 miles, indicating the interval applies to operating environments characterized by more demanding stress on the transmission fluid.
• The 72,000-mile severe-use interval on the 2.0 T-GDI transaxle is expressed in mileage only, without a time-based component, whereas the 1.6 T-GDI interval includes both a mileage threshold and a 48-month cap.
• The capacity range format used for both configurations, rather than a single fixed value, reflects normal manufacturing tolerances and the practical variation in fluid level readings during a service fill procedure.
