Idemitsu ATF Type S Automatic Transmission Fluid — 1 qt (Matic-S/J/D), Anti-Shudder & Seal Protection

Idemitsu ATF Type S (Matic J, D) is a premium 1-quart automatic transmission fluid formulated to meet Nissan and Infiniti Matic-S, Matic-J, and Matic-D specifications for smooth shifts and long-lasting protection.

This specially blended automatic transmission fluid is designed for vehicles requiring Matic-S, Matic-J, or Matic-D performance levels. It combines anti-shudder friction stability, oxidation resistance, and seal conditioning to maintain consistent shift feel and protect components from wear and deposits. The 1-quart bottle is convenient for top-offs, service intervals, or as a shelf-ready spare for routine maintenance.

How will this fluid affect shifting and drivability?

Idemitsu ATF Type S is engineered to deliver consistent friction characteristics so gear changes remain smooth and predictable, even under varied loads and temperatures. That helps reduce shudder and improves driver confidence during acceleration and cruising.

• Stable anti-shudder formulation for smoother engagement
• Controlled friction to preserve shift timing and feel
• Works across operating temperatures to limit shift variability

Does it protect the transmission from breakdown and deposits?

The fluid contains antioxidants and detergents to limit thermal degradation and to keep internal surfaces clean. By resisting oxidation and minimizing varnish and sludge, it helps maintain hydraulic passages and clutch performance over time.

• Superior oxidation resistance extends fluid service life
• Detergent action reduces varnish and deposit buildup
• Helps maintain clear valve bodies and clutch surfaces

Will it prevent leaks and preserve seals?

Formulated with advanced seal conditioners, this ATF helps maintain rubber and elastomer flexibility, lowering the chance of shrinkage or hardening that can lead to leaks. Proper conditioning of seals contributes to longer service intervals and steadier fluid levels.

• Seal-compatible additives reduce hardening and shrinkage
• Helps retain sealing integrity under heat and age
• Reduces risk of leak-related fluid loss between services

Is this the correct choice for my Nissan or Infiniti?

Idemitsu ATF Type S is formulated specifically to meet Nissan/Infiniti requirements calling for Matic-S, Matic-J, or Matic-D specifications. Always verify your vehicle’s owner manual or service guide to confirm the required ATF specification before use.

• Meets Matic-S, Matic-J, Matic-D performance levels
• Suitable for models specifying Idemitsu or equivalent ATF types
• 1-quart size ideal for top-offs and small service jobs

Who is this for? Car owners and technicians working on Nissan and Infiniti vehicles that specify Matic-S, Matic-J, or Matic-D ATF will find this 1-quart Idemitsu bottle convenient and reliable. It’s suited to DIYers doing fluid top-offs, independent shops performing scheduled transmission maintenance, and fleet managers who require a specification-matching fluid to maintain consistent shift quality and reduce the risk of leaks and deposits. If your vehicle’s manual lists one of the Matic specifications covered here, this product provides a focused solution for preserving transmission performance when used according to factory guidance.
