How many quarts of transmission fluid does a Lexus ES 350 take?

The Lexus ES 350 typically requires about 8.5 to 9 quarts of transmission fluid for a full refill, with the exact amount depending on model year and whether you drain only the pan or perform a complete system flush. This range covers most common configurations and service methods.

This article explains the official capacity ranges, what drives variation across years, and practical steps for maintenance and verification. It also notes how to approach refills and what to expect in common service scenarios.

Official capacity ranges for the ES 350

Transmission fluid capacity is the total amount needed to fill the transmission to its proper level, including fluid in the torque converter and cooler lines. For the ES 350, technicians typically cite a total system capacity near 9 quarts. If you only drain the pan and perform a refill, you’re generally replacing about 4 quarts, depending on whether the pan’s filter is involved in the service.

These figures are approximate and can vary by year, transmission variant, and whether a fluid flush or filter replacement is included. For precise numbers, consult the official service manual for your exact year and configuration or ask a Lexus-certified technician.

Below are typical capacity figures used by technicians for this model, acknowledging real-world variations.

• Total system capacity (including torque converter and cooler lines): about 9 quarts.


• Pan drain and refill capacity (no fluid flush): about 4 quarts.


• Factors that influence the exact amount: model year, transmission variant (8-speed vs older setups), whether the transmission filter is replaced, and whether a full system flush is performed.

In practice, plan for roughly 8–9 quarts for a full refill and about 4 quarts for a standard pan drain and fill. Always verify the exact specification for your year and transmission configuration in the service manual or with a Lexus technician.

Practical guidance for maintenance and verification

When performing a transmission fluid service on a Lexus ES 350, follow the manufacturer’s guidelines for safe handling and correct filling procedures. Use the recommended fluid specification for your year and transmission, and avoid mixing fluids. After filling, run the vehicle through the gears and recheck the level on level ground and at the proper operating temperature as directed by the service manual. Some model years use a dipstick-based check, while others require a specialized procedure or tool to verify the fluid level.

Summary

For a straightforward answer: a Lexus ES 350 generally takes about 8.5–9 quarts of transmission fluid for a full refill, with a pan drain and refill typically around 4 quarts. Exact totals vary by model year, transmission type, and service method. Always consult the vehicle’s service manual or a Lexus-certified technician for your specific year and configuration.

How much is a transmission fluid change for a Lexus ES350?

The cost for a Lexus ES 350 transmission fluid change can range from approximately $350 to over $700, depending on the service type and where you get it done. A standard fluid change might be on the lower end, while a more comprehensive flush performed at a dealership could be closer to $600 or more. 
Factors that influence cost

• Service type: A simple "drain and fill" is typically less expensive than a full "transmission fluid flush," which removes more of the old fluid. 
• Labor and parts: Dealerships usually have higher costs for both parts and labor compared to independent mechanics. 
• Vehicle age: Older models may have slightly different service costs than newer ones. 

How to estimate the cost for your specific vehicle

• Use online estimators: Websites like Kelley Blue Book and YourMechanic provide cost estimates based on your car's make, model, and year. 
• Contact local shops: Get quotes from both dealerships and independent mechanics in your area to compare pricing.

Important considerations

• Dipstick availability: Many modern Lexus models, including some ES 350s, do not have a traditional dipstick, making professional service necessary to check the fluid level and perform the change. 
• Maintenance schedule: Follow the recommended maintenance schedule in your owner's manual for the best performance and longevity of your transmission.
