1. What Type of Transmission Fluid Does a Toyota 4Runner Use?

Your Toyota 4Runner is designed to use Toyota Genuine ATF WS (Automatic Transmission Fluid – World Standard). Using the correct transmission fluid is crucial for the longevity and performance of your transmission. According to your 2019 owner’s manual: “Using transmission fluid other than “Toyota Genuine ATF WS” may cause deterioration in shift quality, locking up of the transmission accompanied by vibration and, ultimately, damage to the vehicle’s transmission.” This fluid is specifically formulated to meet the demands of your 4Runner’s transmission, ensuring smooth shifting and optimal lubrication.

Toyota Genuine ATF WS: This is the recommended fluid for your 4Runner.
Why it Matters: Using other fluids can lead to poor performance or damage.
Where to Buy: You can purchase this fluid at millertoyota.net or your local Toyota dealership.

Using the correct transmission fluid is vital for your Toyota 4Runner. The fluid ensures smooth shifting, protects against wear, and helps maintain optimal performance. Always opt for Toyota Genuine ATF WS to avoid potential damage and maintain your vehicle’s reliability.

2. How Much Transmission Fluid is Needed for a Toyota 4Runner Drain and Fill?

For a standard drain and fill service on your Toyota 4Runner, you will typically need about 5 to 6 quarts of Toyota Genuine ATF WS fluid. This amount can vary slightly depending on how thoroughly the old fluid drains.

Typical Amount: 5-6 quarts for a drain and fill.
Factors Influencing Amount: How much of the old fluid is drained.
Why It’s Important: Ensures proper lubrication and smooth operation.

Knowing the correct amount of transmission fluid is essential for maintaining your Toyota 4Runner. Using the right quantity ensures that your transmission operates smoothly and efficiently, preventing potential issues down the road.

3. What is the Total Transmission Fluid Capacity of a Toyota 4Runner?

The total transmission fluid capacity of a Toyota 4Runner is approximately 11.3 quarts. However, during a standard drain and fill service, you typically only replace about half of this amount, as much of the fluid remains in the torque converter and transmission lines.

Total Capacity: Approximately 11.3 quarts.
Drain and Fill: Replaces about 5-6 quarts.
Why the Difference: Some fluid stays in the torque converter and lines.

Understanding the total capacity versus the drain and fill amount helps you manage your transmission maintenance effectively. Knowing these figures ensures you add the right amount of new fluid, keeping your 4Runner’s transmission in excellent condition.

4. What are the Steps to Check the Transmission Fluid Level on a Toyota 4Runner?

Checking the transmission fluid level on your Toyota 4Runner requires specific steps to ensure accuracy:

Preparation: Park your 4Runner on a level surface.
Warm-Up: The engine should be warmed up but not excessively hot. The transmission fluid temperature should be between 104°F and 113°F (40°C and 45°C).
Accessing Maintenance Mode:
- With the vehicle off, install a jumper wire from pins 4 and 13 on your OBDII port.
- Start your vehicle and make sure all electrical systems are off.
- If you connected the correct terminals, a lot of the dash lights will be flashing on and off. This means you are in maintenance mode.
- With your foot on the brake, cycle from Park to Neutral a couple of times. Once complete, put the transmission back into Park.
- From Park and with a foot on the brake, go to Neutral. Cycle back and forth from Neutral and Drive quickly until your “D” indicator on the dash becomes solid. When you see this, put the shifter back into Park and remove the jumper cable previously installed.
- Now, the vehicle is in fluid check mode, allow it to idle until you reach the desired temp. When the fluid temperature is below 104F, the “D” light will be off. When the temp is at 104F, the “D” light will come on solid. If the temp exceeds 113F, the “D” will blink, letting you know it’s too hot to check the fluid level.
Locate the Check Plug: Find the transmission fluid check plug on the transmission pan. It typically requires a 5mm Allen wrench.
Remove the Check Plug: With a catch container in place, remove the check plug.
- If fluid drips out, the level is correct.
- If no fluid comes out, the level is too low and needs to be adjusted.
Reinstall the Plug: Once the fluid level is correct (a slight drip), reinstall the check plug with a new gasket and torque to 15 ft-lbs.

Level Surface: Park on a level surface.
Temperature: Ensure the transmission fluid is between 104-113°F (40-45°C).
Check Plug: Remove the check plug and observe the fluid.
Proper Level: Fluid should drip slightly from the check plug.

Regularly checking your transmission fluid level ensures your Toyota 4Runner operates at its best. Proper fluid levels prevent transmission issues and maintain smooth driving performance.

5. What are the Signs That My Toyota 4Runner Needs a Transmission Fluid Change?

Several signs indicate that your Toyota 4Runner may need a transmission fluid change:

Difficulty Shifting: Hesitation or rough shifting between gears.
Slipping Gears: The transmission slips out of gear unexpectedly.
Unusual Noises: Whining, clunking, or humming sounds from the transmission.
Burning Smell: A noticeable burning odor coming from the engine area.
Dark or Dirty Fluid: Transmission fluid that appears dark, smells burnt, or contains particles.
Shifting Issues: Difficulty or roughness when shifting gears.
Unusual Sounds: Noises like whining or clunking.
Fluid Condition: Dark, burnt-smelling fluid.

Recognizing these signs early can prevent significant transmission damage. Addressing these issues promptly with a transmission fluid change can keep your Toyota 4Runner running smoothly and reliably.

6. What is the Difference Between a Transmission Fluid Drain and Fill vs. a Flush on a Toyota 4Runner?

The difference between a transmission fluid drain and fill and a flush lies in the extent of the fluid replacement:

Drain and Fill: This involves removing the drain plug to drain the old fluid from the pan, then refilling it with fresh fluid. This method typically replaces about 5-6 quarts of the total 11.3 quarts.
Flush: A transmission flush replaces nearly all of the old fluid. This is typically done using a machine that connects to the transmission cooler lines to circulate new fluid through the entire system, pushing out the old fluid.
Drain and Fill: Partial fluid replacement, about half the total capacity.
Flush: Complete fluid replacement using a machine.
Considerations: Fluid condition, maintenance history, and vehicle mileage.

Choosing between a drain and fill and a flush depends on your vehicle’s condition and maintenance history. Regular drain and fill services are often sufficient for vehicles with consistent maintenance, while a flush might be recommended for high-mileage vehicles or those with neglected maintenance records.

7. How Often Should I Change the Transmission Fluid in My Toyota 4Runner?

The recommended interval for changing the transmission fluid in your Toyota 4Runner varies depending on driving conditions and whether you are performing a drain and fill or a full flush. Toyota recommends inspecting the fluid at 60,000 miles.

Normal Conditions: For drain and fill, every 30,000 miles.
Severe Conditions: For drain and fill, every 15,000 to 20,000 miles.
Full Flush: Typically recommended every 60,000 to 100,000 miles, or as needed based on fluid condition.

Severe conditions include:

Towing
Off-roading
Frequent stop-and-go traffic

Regular transmission fluid changes are crucial for maintaining your Toyota 4Runner’s performance and longevity. Following the recommended intervals ensures your transmission remains in good working condition, preventing costly repairs.

8. What are the Potential Problems if I Don’t Change My Toyota 4Runner’s Transmission Fluid?

Failing to change your Toyota 4Runner’s transmission fluid can lead to several problems:

Overheating: Old, degraded fluid loses its ability to cool the transmission, leading to overheating.
Poor Lubrication: Lack of proper lubrication causes increased wear and tear on transmission components.
Rough Shifting: Dirty fluid can cause the transmission to shift hard or erratically.
Transmission Damage: Severe neglect can result in significant damage to the transmission, requiring costly repairs or replacement.
Overheating: Reduced cooling efficiency.
