The 4Runner transmission fluid capacity for the 5th-generation model (2010 to 2024, 5-speed automatic) is roughly 11 quarts when completely dry, but a normal pan drain-and-refill replaces only about 3 quarts or so, because the torque converter and cooler hold the rest. Use Toyota Genuine ATF WS, check the level at the specified temperature, and confirm the numbers for your exact model year in the owner’s manual or service manual.
4Runner Transmission Fluid Capacity at a Glance (2010 to 2024)
| Item | Approximate figure |
|---|---|
| Fluid type | Toyota Genuine ATF WS |
| Dry fill (whole system) | About 11 quarts (roughly 10.4 to 10.7 liters) |
| Pan drain and refill | About 3 liters, or 3.2 quarts, in Toyota service data |
| Level check | Check plug at the specified fluid temperature |
These figures come from Toyota service data for the A750-series transmission and from published owner procedures. Procedures can differ by model year, so verify them for yours before ordering fluid.
Why a Drain and Refill Does Not Replace All the Fluid
When you drop the pan or open the drain plug, you only remove the fluid in the pan. The torque converter, valve body and cooler lines keep most of the rest. That is why the amount you put back is far less than the total capacity.
- A drain and refill gradually renews the fluid.
- Repeating it a few times replaces more of the old fluid.
- A machine flush replaces more at once, but ask a trusted shop about their method and the age of the fluid first.
What Fluid to Use
Toyota specifies ATF WS for the 5th-generation 4Runner. Do not mix it with other fluid types, and do not use a generic fluid unless its label states that it meets the Toyota WS specification. For more detail, see our 4Runner automatic transmission fluid types guide.
How to Check the Level (No Dipstick)
The 5th-generation 4Runner has no transmission dipstick. Instead, the pan has a check plug (sometimes called an overflow or level plug) that is removed when the fluid is at a set temperature.
- Park on level ground and set the parking brake.
- Bring the fluid to the temperature in your service procedure. Published DIY procedures use roughly 104 to 113 degrees Fahrenheit.
- Read the fluid temperature with a scan tool or the method described in your manual.
- With the temperature in range, remove the check plug. A thin trickle of fluid means the level is correct.
- If nothing comes out, add fluid and re-check. If a lot pours out, let it drain until it slows to a trickle.
- Reinstall the plug with a new gasket or washer.
Because the fluid expands as it warms, checking outside the range gives a false reading. Procedures also specify whether the engine runs during the check, so follow the factory steps.
DIY Drain and Refill Overview
This is a summary, not a replacement for the service manual. If you are not comfortable working under the vehicle or reading a service procedure, have a shop do it.
- Support the vehicle safely on jack stands on level ground.
- Remove the fill plug first, so you do not drain the pan and find you cannot refill it.
- Remove the drain plug and catch the fluid. Measure how much comes out.
- Reinstall the drain plug with a new gasket, torqued to the specification in your manual.
- Refill with the measured amount of ATF WS.
- Bring the fluid to the specified temperature and set the final level at the check plug.
- Reinstall all plugs to torque specifications, and check for leaks.
You need a hex socket set, a torque wrench, a fluid pump, a drain pan with measurements, a way to read transmission temperature and new gaskets. Dispose of old fluid at a recycling center.
Service Interval
Toyota’s schedules for the 5th generation focus on inspecting the fluid, with replacement recommended for severe use such as towing or heavy loads. Many owners change it earlier. Check your Warranty and Maintenance Guide. If you tow, haul or drive off-road, consider a shorter interval.
Other Generations and the 2025 4Runner
Capacity and fluid type differ for the 3rd generation (1996 to 2002, 4-speed), the 4th generation (2003 to 2009) and the 6th generation (2025 and newer, 8-speed). Published figures for older models conflict from source to source, so do not copy a number from a 5th-generation guide.
Use the owner’s manual or ask a dealer to look up your VIN. The 2025 model has no transmission dipstick either, so its service procedure also relies on a defined method.
Common Mistakes
- Overfilling or underfilling, which can cause erratic shifting or damage.
- Checking the level at the wrong temperature.
- Using the wrong fluid or mixing types.
- Forgetting to replace the plug gaskets, which can cause leaks.
- Draining the pan before confirming you can refill it.
Frequently Asked Questions
How much transmission fluid does a 2010-2024 4Runner hold?
The 5-speed automatic in the 5th-generation 4Runner holds roughly 11 quarts (about 10.4 to 10.7 liters) when completely dry, according to Toyota service data for the A750-series transmission. A normal pan drain-and-refill replaces only part of that. Confirm your figure in the owner’s manual or service manual.
How many quarts do I need for a drain and refill?
Toyota service data for this transmission lists about 3 liters (roughly 3.2 quarts) for a drain and refill, but the amount that actually drains can differ. Buy a little extra, measure what comes out, replace what you drained and set the final level with the check plug procedure.
Why does the 4Runner transmission have no dipstick?
The 5th-generation 4Runner uses a sealed design with a check plug on the pan instead of a dipstick. The level is checked at a specified fluid temperature by removing the check plug while the fluid is in range. Follow the factory procedure for your year.
What temperature should the fluid be to check the level?
Published DIY procedures for the 5th-generation 4Runner use a window of about 104 to 113 degrees Fahrenheit, read with a scan tool or the vehicle’s maintenance-mode indicator. Always follow the exact procedure in your service manual, since checking at the wrong temperature gives a false level.
Can I use the same fluid amount for every 4Runner generation?
No. Capacity and fluid type vary by generation, transmission and sometimes model year. A 3rd-generation 4-speed, a 4th-generation 5-speed and the 6th-generation 8-speed each have different figures. Look up the specification for your VIN in the owner’s manual or from a dealer.
Conclusion
For a 2010 to 2024 4Runner, plan on roughly 11 quarts total but only about 3 quarts for a simple pan drain and refill, set the final level at the check plug and use ATF WS. Double-check each number against your owner’s manual or service manual before you start.
