Idemitsu ATF Type TLS-LV (WS) Automatic Transmission Fluid — 5 qt, Low-Viscosity High-Temperature Stability

This 5-quart pack of Idemitsu ATF Type TLS-LV (also known as WS) is engineered for modern automatic gearboxes that require a low-viscosity, high-performance fluid. It balances fuel efficiency with precise frictional control so transmissions shift smoothly while resisting oxidation, deposits, and thermal breakdown. The product is presented in a convenient volume suitable for service fills and top-ups.

How does Idemitsu ATF TLS-LV help my transmission perform better?

The fluid’s formulation focuses on controlled friction characteristics and advanced anti-wear chemistry to promote consistent shift feel and protect internal components. By maintaining stable viscosity across temperatures, it reduces slippage and helps gears and bearings resist wear.

• Optimized low-viscosity base for fuel-efficient operation
• Friction modifiers tuned for smooth, predictable shifts
• Wear inhibitors that protect gears and bearings

Will this fluid last through long service intervals and heat exposure?

Idemitsu TLS-LV is formulated for oxidative and thermal stability, so it maintains protective properties under extended use and elevated temperatures. That helps reduce varnish and sludge formation, keeping hydraulic passages and clutch surfaces cleaner between services.

• High resistance to oxidation and thermal breakdown
• Superior deposit control to limit varnish and sludge
• Extended fluid life under typical operating conditions

Is Idemitsu ATF Type TLS-LV compatible with my vehicle and how is it specified?

This ATF matches the TLS-LV/WS performance profile required by certain automatic transmissions; check your owner’s manual or dealer specification to confirm suitability. Its properties are aimed at transmissions that call for a low-viscosity ATF with specific friction and anti-shudder requirements.

• Meets TLS-LV/WS performance characteristics used by specified manufacturers
• Best used where a low-viscosity ATF is recommended
• Refer to vehicle documentation for compatibility and fill volumes

What practical benefits will I notice after switching to this ATF?

Drivers commonly see smoother shift transitions, reduced transmission noise under load, and stable operation across varied temperatures. Technicians will appreciate its deposit control and protective additives that help preserve metal surfaces and hydraulic components.

• Improved shift quality and anti-shudder performance
• Reduced risk of corrosion and metal surface wear
• Consistent performance across a wide temperature range

Who is this for: Idemitsu ATF Type TLS-LV (WS) — 5 Qt is intended for vehicle owners, mechanics, and fleet operators who need a low-viscosity automatic transmission fluid compatible with TLS-LV/WS specifications. It suits routine transmission servicing, drain-and-fill jobs, or keeping a workshop supply on hand when manufacturers specify this fluid type. Always verify your vehicle’s required ATF specification before use and follow recommended service intervals.
