Fluid Type - Toyota Genuine ATF WS
This is a TOYOTA-SPECIFIC requirement. ATF WS is not interchangeable with other transmission fluids:
Fluid Capacity - 13.2 Quarts (12.5 Liters)
The 13.2 quart (12.5 liter, 11.0 imperial quart) figure is a reference specification:
Your 2024+ Land Cruiser has a protective system that monitors transmission fluid temperature. It's important to understand how this works - it can help you avoid serious transmission damage.
How the Protection System Works
If the tires spin continually when the vehicle becomes stuck in mud, dirt or snow, or if the accelerator pedal is depressed and released repeatedly while driving, the automatic transmission temperature may become too high and the automatic transmission may be damaged.
To avoid damaging the automatic transmission, the system may temporarily lock the gear. If the automatic transmission temperature falls, the gear locking is canceled and the automatic transmission is returned to normal operation.

Why ATF WS Matters for Your J250
The 2024+ Land Cruiser J250 uses an 8-speed automatic transmission paired with the 2.4L turbocharged i-FORCE MAX hybrid powertrain. This combination generates 326 hp and 465 lb-ft of torque, placing significant demands on the transmission system.
Toyota Genuine ATF WS is engineered specifically for:
- Hybrid powertrains: The transmission manages both gas engine and electric motor power delivery
- Turbo compatibility: Higher oil film strength for the extra pressure from turbocharging
- Temperature stability: Maintains viscosity across the wide temperature range of a hybrid system
- Shift quality: Ensures smooth, precise shifts in the 8-speed transmission
The Critical Warning is Not a Suggestion
Using non-approved transmission fluid is one of the fastest ways to damage an automatic transmission and void your warranty. The NOTICE in your owner's manual is a warranty and reliability statement.
What Makes ATF WS Different
- Approved for: Toyota automatic transmissions including hybrid variants
- NOT approved for: Dexron-based fluids, competing brand ATFs, or older Toyota specifications
