Aisin Warner JWS 3324

Specification Aisin Warner JWS 3324 is a technical standard developed by the Japanese transmission manufacturer Aisin Warner for automatic transmissions with hydraulic control, including 6‑speed and CVT models, installed in passenger and commercial vehicles with gasoline, diesel and hybrid engines. The JWS 3324 requirements provide stable viscosity in the 5W‑30 range, high resistance to oxidation, wear and corrosion protection, as well as optimized friction characteristics for smooth gear shifting and long‑lasting operation of sliding friction elements. The standard guarantees compatibility with emission control systems, including catalysts and DPF, without increased SAPS content, which is important for modern low‑emission engines. When selecting a lubricant marked JWS 3324, service center technicians gain confidence that it meets Aisin OEM‑manufacturer recommendations, and drivers receive reliable transmission protection and extended service life even under high loads.
