🔧 Transaxle Fluid - Drain and Fill

Your Camry uses a hybrid transaxle, not a conventional automatic transmission. The fluid service is a drain-and-fill only, using the correct Toyota WS fluid and checking the level at the overflow plug with the fluid at the proper temperature.

Difficulty Level: Intermediate | Estimated Time: 1.5-2.5 hours

⚠️ Safety & Precautions

• Hybrid system voltage can be present even with the engine off. Keep hands away from orange HV cables and connectors.
• Work on level ground and support the vehicle securely on jack stands before getting underneath.
• Transmission fluid may be hot after driving. Let the vehicle cool before opening the drain plug.
• Battery disconnect is not required for a normal fluid change.
• Do not overfill. This transaxle level is set by overflow at a specific fluid temperature.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Access the transaxle

• Raise the front of the vehicle with a floor jack and support it with jack stands.
• Remove the lower splash shield if equipped. Use a 10mm socket.
• Keep the car level for the final fill.

Step 2: Remove the fill plug first

• Use a 24mm socket to loosen the fill plug before draining.
• This confirms you can refill it later.

Step 3: Drain the old fluid

• Place the drain pan under the transaxle.
• Use the 24mm socket to remove the drain plug.
• Let the fluid drain fully.
• Install a new drain plug gasket.
• Torque to 39 Nm (29 ft-lbs).

Step 4: Refill with Toyota WS fluid

• Install the drain plug if it was removed during the drain step.
• Use a fluid transfer pump to add Toyota WS fluid through the fill hole.
• Add fluid until it begins to run back out of the fill opening.
• Install a new fill plug gasket.
• Thread in the fill plug by hand first, then snug it with the 24mm socket.
• Torque to 39 Nm (29 ft-lbs).

Step 5: Set the final fluid level

• Start the vehicle and let it idle.
• Use a scan tool or infrared thermometer to monitor transaxle fluid temperature.
• Remove the overflow/check plug if equipped for your drain-and-fill point.
• Fluid should be a slow drip at the correct temperature range.
• If needed, add more Toyota WS fluid with the fluid transfer pump until it drips from the level port.
• Reinstall the level/overflow plug with a new gasket.
• Torque to 39 Nm (29 ft-lbs).

Step 6: Reassemble and inspect

• Reinstall the splash shield using the 10mm socket.
• Lower the vehicle.
• Check underneath for leaks after the test drive.
