How many quarts of transmission fluid for 2016 Lexus RX 350?
For a complete transmission fluid replacement on the 2016 RX 350, expect about 9 quarts. A drain-and-fill typically requires around 4–5 quarts.
Understanding capacity and service options
The total amount you need depends on the service method: whether you replace the fluid with a filter, perform only a drain and fill, or run a machine-assisted flush. The RX 350 uses an 8-speed automatic transmission that typically requires Dexron VI–compatible ATF. Capacities are approximate and can vary slightly by model year and maintenance history.
Typical service quantities
Below are the common scenarios and the approximate ATF quantities involved. Use these as guidelines and confirm with the owner's manual or a Lexus dealer for your exact vehicle.
- Drain-and-fill (pan drop not always required): roughly 4–5 quarts.
- Full replacement with pan removal and filter change: about 9–9.5 quarts.
- Transmission flush (machine-assisted): typically 9–12 quarts, depending on the method and whether cooler lines are included.
Note: If your vehicle has not been serviced recently, or if there are leaks or a worn transmission, the amount needed may differ. Always use the recommended ATF specification for Lexus (Dexron VI or the Lexus-recommended fluid) and consider having the service performed by a trained technician.
Why the numbers vary
Transmissions are complex, with fluid distributed between the pan, torque converter, valve body, and cooling lines. A full replacement that includes the filter requires more fluid than a simple drain-and-fill; a flush can introduce additional fluid through the cooler and lines, affecting the total.
Summary
In summary, plan on about 9 quarts for a complete transmission fluid replacement on a 2016 Lexus RX 350. For a basic drain-and-fill, you can expect around 4–5 quarts. Always verify with your owner's manual or a Lexus service center, and use the specified Dexron VI ATF.
How much is a transmission fluid change for a Lexus RX 350?
The cost to change the transmission fluid on a Lexus RX 350 typically ranges from approximately $350 to $550. This price can vary based on factors such as the age of the vehicle, where you get the service done (dealer vs. independent shop), and the specific parts used.

Cost breakdown and factors
- Dealer service: Expect to pay in the higher end of the range, often between $396 and $525 or more. Dealers use official, manufacturer-recommended parts and have factory-trained technicians, which can lead to higher labor rates.
- Independent shop: Costs are often lower, potentially between $352 and $465 or more. Independent shops may use aftermarket parts, which are typically less expensive than official OEM parts.
- Vehicle model year: The specific year of your Lexus RX 350 can influence the price, with some years potentially having slightly different requirements or costs.
- Parts and labor: The final cost depends on the price of the transmission fluid, any necessary gaskets or filters, and the labor rate of the shop performing the service.
What to consider
- Maintenance schedule: Follow the maintenance schedule in your owner's manual. For many Lexus RX 350 models, a transmission fluid change is recommended every 30,000 to 60,000 miles, depending on driving conditions.
- Fluid flush vs. change: A standard fluid change typically replaces less than half the fluid. For the best protection, especially in a vehicle with an older fluid, a professional transmission fluid flush may be recommended to remove the old, contaminated fluid.
- "Lifetime" fluid: Some models use "lifetime" transmission fluid, meaning it is not designed to be changed under normal circumstances. However, a transmission can still fail, especially outside of the warranty period. If you are concerned or experiencing shifting issues, it is best to consult with a dealer or a trusted mechanic.
How many quarts of oil does a 2016 Lexus RX350 take?
The 2016 Lexus RX 350 has an oil capacity of approximately 5.7 quarts (or 5.5 liters) with an oil filter change, but the exact capacity can be slightly higher if the vehicle has a towing package. A dry engine refill may require 9.5 to 10.5 quarts. It is crucial to check the dipstick after filling to ensure the correct level.
- Standard oil change: 5.7 quarts (5.5 liters) with an oil and filter change.
- With towing package: The capacity is around 6.1 quarts.
- Dry fill: 9.5 to 10.5 quarts.
- Important: Always check the oil level with the dipstick after refilling to ensure it is at the correct level and add more if necessary.

How many quarts of transmission fluid does a 350 transmission take?
A TH350 transmission's fluid capacity varies, but it typically holds about 10-13 quarts when completely dry, with the torque converter holding around 4 quarts. For a standard fluid and filter change, start with about 4-6 quarts and then add fluid while running until you reach the correct level on the dipstick.
Capacity breakdown
- Dry fill (completely empty): Approximately 10-13 quarts
- Fluid and filter change: Start with about 4-6 quarts. The total will be higher and is best checked on the dipstick after the engine has been running and cycled through the gears.
- Torque converter: Holds about 4 quarts
- Aftermarket deep pan: May require more fluid, up to 12 quarts or more
Important tips
- Fill in stages: When doing a filter change, add about 4-6 quarts initially. Start the engine, let it run, and check the fluid level on the dipstick.
- Check the dipstick: Never overfill. The final amount should be determined by the dipstick level after the engine is warm and the transmission is in park.
- Convertor first: If you have the transmission out, add 2 quarts directly into the torque converter before installing it.
- Use the right fluid: The TH350 originally used Dexron III, and it's important to use a fluid that is compatible with it.
