Toyota 00279-000T4 is a factory-formulated T-IV automatic transmission fluid sold in 192-ounce bottles and offered here as a six-pack for ready installation and maintenance.

This genuine Toyota (Lexus) T-IV fluid is engineered to meet the specifications of older Toyota and Lexus automatic transmissions that call for Type T-IV. Supplied in large, ready-to-use containers, the six-bottle pack simplifies scheduled service, bulk top-ups, and fleet maintenance. The product is made in the United States and packaged for universal fit where T-IV is specified.

Which vehicles and transmissions require this T-IV fluid?

Use this fluid when your vehicle’s owner manual or transmission label specifies Toyota T-IV (T-4) ATF. It is commonly required by many Toyota and Lexus automatic transmissions from earlier model years and specific gearboxes that list T-IV compatibility.

• Fits Toyota and Lexus models that list ATF Type T-IV in the manual.
• Suitable for legacy automatic transmissions requiring T-IV chemistry.
• Also useful for technicians maintaining multiple Toyotas or fleet vehicles.

How much fluid does each bottle contain, and how does the 6-pack help?

Each container holds 192 ounces (equivalent to 1.5 US gallons), which covers full fluid changes for many transmissions or multiple top-ups. Buying a six-pack reduces per-bottle cost and keeps a ready supply for scheduled service or multi-vehicle shops.

• 192 ounces per bottle for large-capacity fills or several vehicles.
• Six bottles provide bulk convenience and lower unit cost.
• Boxes sized and weighted for easier storage and handling in a garage or shop.

What are the practical installation and handling points?

The fluid is supplied ready to pour—no mixing required—so installation is straightforward for DIYers and pros. Always follow the vehicle manufacturer’s fill, dipstick, or scan-based level procedures and use the correct refill method (fill tube, funnel, or pump) to avoid overfill or contamination.

• Ready-to-install formulation—pour directly into transmission service point.
• Store in a cool, dry place and keep caps sealed to prevent contamination.
• Refer to the vehicle manual for correct fill quantity and procedure.

What should I expect from genuine Toyota-branded ATF quality?

Genuine Toyota fluids are produced to match factory specifications and manufacturing tolerances, helping maintain transmission performance when the correct fluid type is used. Using manufacturer-branded ATF helps ensure compatibility with seals, friction materials, and hydraulic circuits designed around T-IV chemistry.

• Factory-formulated to Toyota/Lexus T-IV specification for compatible units.
• Manufactured in the United States under Toyota parts standards.
• Packaged to reduce risk of contamination during storage and use.
