Idemitsu ATF Type TLS-LV (WS) synthetic automatic transmission fluid — 1 Quart, low-viscosity, smooth shifts & wear protection

Idemitsu ATF Type TLS-LV (WS) is a synthetic automatic transmission fluid formulated to deliver smoother shifts, improved fuel economy, and long-lasting protection for modern automatic gearboxes.

This one-quart bottle contains Idemitsu's TLS-LV (WS) formula engineered for transmissions that require low-viscosity ATF with precise friction properties. Its additive package helps reduce wear, control deposits, resist oxidation, and maintain consistent shift feel across a wide temperature range. Use it for top-ups, scheduled changes, or when a vehicle manufacturer specifies this type of fluid.

How does this ATF improve shift quality and drivability?

Idemitsu TLS-LV (WS) is formulated with friction modifiers calibrated to produce consistent clutch engagement and predictable shift timing. That helps reduce shudder, hesitation, and rough transitions during gear changes while keeping hydraulic controls responsive.

• Precisely engineered frictional characteristics for smooth clutch engagement
• Advanced friction-reducing additives minimize shudder and harsh shifts
• Maintains stable viscosity for reliable hydraulic pressure

Will this fluid help my vehicle use less fuel?

The low-viscosity base and fuel-economy additives lower internal drag inside the transmission, which can contribute to improved efficiency under many driving conditions. While savings vary by vehicle and driving habits, the TLS-LV (WS) grade is designed to support better fuel economy compared with thicker conventional ATFs.

• Optimized low-viscosity formulation reduces parasitic losses
• Additives tuned to decrease internal friction and mechanical drag
• Beneficial for vehicles where manufacturer specifies low-viscosity ATF

How does Idemitsu protect the transmission from wear and deposits?

This transmission fluid contains robust anti-wear and detergent components to protect gear teeth, bearings, and clutch surfaces while preventing varnish and sludge buildup. It also resists oxidation at high temperatures, extending fluid life and maintaining performance over longer service intervals.

• Superior wear protection for gears and bearings
• Excellent deposit control to keep valves and passages clean
• High oxidation and thermal resistance for extended fluid life

Is this product compatible with my vehicle's transmission specifications?

Use Idemitsu ATF Type TLS-LV (WS) when your owner's manual or service documentation specifies TLS-LV, WS, or equivalent low-viscosity ATF. Always verify compatibility with manufacturer requirements and avoid mixing with incompatible fluid types unless permitted by the vehicle maker.

• Designed for transmissions requiring TLS-LV / WS grade ATF
• One-quart size suitable for top-ups and partial changes
• Check your owner's manual or dealer for exact specification match

Who is this for: Drivers, fleet technicians, and DIY enthusiasts who need a modern low-viscosity automatic transmission fluid that prioritizes smooth shifts, deposit control, and extended thermal stability. Ideal for vehicles specifying TLS-LV (WS) ATF or for anyone seeking fuel-economy-oriented transmission fluid in a convenient one-quart bottle.
