Idemitsu ATF Type TLS Automatic Transmission Fluid – 5 Quart for Toyota/Lexus/Scion, Anti-Shudder & Seal Conditioning

Idemitsu ATF Type TLS is a 5-quart automatic transmission fluid formulated to meet Toyota/Lexus/Scion specifications for smooth shifting, anti-shudder performance, and long-lasting protection.

Designed as a factory-compatible fluid for many Toyota, Lexus and Scion models, this ATF Type TLS delivers tailored frictional properties, oxidation resistance and seal conditioning to keep automatic transmissions running clean and reliable. It’s blended to protect gears and bearings while minimizing deposits and helping prevent leakage caused by aging seals.

How does Idemitsu ATF Type TLS improve shift quality?

The fluid’s engineered friction characteristics provide consistent engagement between clutch plates and bands so the transmission shifts smoothly under varied driving conditions. That controlled friction also reduces the risk of shudder during torque converter operation, which preserves driver comfort and component life.

• Stable friction formula tuned for Toyota/Lexus/Scion shift feel
• Anti-shudder performance reduces judder under load
• Consistent viscosity for reliable hydraulic response

What protection does this ATF offer against wear and breakdown?

Advanced anti-wear additives shield gears, bearings and clutch surfaces from metal-to-metal contact, helping extend service life. The base oil and additives resist oxidation and thermal degradation to maintain fluid integrity over long drain intervals.

• Anti-wear chemistry for gear and bearing protection
• Excellent oxidation resistance to reduce thickening and varnish
• High flash point (174°C) indicating thermal stability

Will Idemitsu ATF Type TLS keep my transmission clean and leak-free?

This formulation includes detergents and dispersants to minimize sludge and varnish formation, preserving valve body passages and solenoid function. It also conditions seals—helping prevent shrinkage, hardening and cracking that can lead to leaks.

• Superior detergency to limit deposits and sticking components
• Seal compatibility and conditioning to reduce leak risk
• Maintains clarity and flow for reliable hydraulic operation

How do I know if this 5-quart pack is right for my vehicle?

This five-quart container suits fluid changes and top-ups for many passenger cars and light trucks that specify Type TLS or equivalent Toyota/Lexus/Scion ATF standards. Check your owner’s manual or service guide for the exact specification and required capacity before purchase.

• Ideal for complete fluid changes on small to medium transmissions
• Convenient size for workshops and vehicle owners performing maintenance
• Matches OEM friction and chemical requirements when Type TLS is specified

Who this product is for: Idemitsu ATF Type TLS 5-quart is intended for owners and mechanics who service Toyota, Lexus and Scion automatic transmissions that call for Type TLS or equivalent fluids. It’s suited to drivers seeking an OEM-compatible transmission fluid that emphasizes smooth shifting, deposit control and extended protection for gears, bearings and seals—without overpromising results beyond standard maintenance benefits.
