Purpose and Specifications

RAVENOL ATF RED-1 1L is a premium synthetic automatic transmission fluid designed for 5-speed Hyundai Powertech A5SR1 and A5SR2 transmissions in vehicles like KIA Sorento, KIA Mohave, Hyundai Genesis Coupe, Hyundai H-1, Grand Starex, and i800. It matches exact specs including ATF RED-1, Hyundai 04500-00140, and KIA 04500-00140 or UM040-CH020.

This red-colored oil uses advanced synthetic base stocks that flow smoothly at low winter temps down to -54°C pour point, keeping shifts crisp even in freezing conditions. It stays thick and protective during hot drives up to 150°C operating temps, fights wear, cuts corrosion, prevents foam, and cools the transmission efficiently for smoother, longer-lasting performance.

• Maximum wear protection in all driving conditions
• Excellent cold-start lubrication for quick engagement
• High thermal stability reduces breakdowns on long trips
• Balanced friction for precise, jerk-free shifting

When to Use / Replace?

Use RAVENOL ATF RED-1 as a direct OEM replacement during routine service or if your transmission slips, hesitates, or overheats. Replace every 60,000 km or 48 months under normal driving; cut to 30,000 km or 24 months for towing, city stop-go, or extreme temps. Shelf life is 5 years unopened in cool, dry storage.

Users report noticeably smoother gearbox operation after drain-and-fill, with no hesitation even in winter.
