🔧 Camry - Transaxle (eCVT) Fluid Drain & Fill

Your Camry Hybrid uses a sealed hybrid transaxle (Toyota eCVT) with no dipstick, so fluid service is done by draining the old fluid and refilling through the fill plug until it just starts to run back out. This refreshes the fluid and helps long-term transaxle life without doing a power flush.

Difficulty Level: Intermediate | Estimated Time: 1.0-2.0 hours

⚠️ Safety & Precautions

• Work on a cool-to-warm transaxle, not hot. Hot ATF can burn skin.
• Keep the car level and supported on jack stands before you go underneath.
• Avoid touching orange cables/connectors (high-voltage hybrid wiring).
• Do not use a “flush machine” on the hybrid transaxle.
• Battery disconnect is not required for a drain & fill, but keep the car OFF (READY light OFF).

📋 Before You Begin

• Park on level ground, set the parking brake, and place wheel chocks behind the rear wheels.
• Start the car and let it run 5–10 minutes, then shut it OFF. Warm fluid drains more completely.
• Raise the front of the car with a floor jack and support it on jack stands. Keep the car as level as possible.
• Gather your fluid transfer pump (a hand pump that screws into the ATF bottle) because the fill hole is on the side of the transaxle.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the engine under cover

• Use a 10mm socket and trim clip removal tool to remove the front under cover/splash shield fasteners.
• Set the fasteners aside in a tray so you don’t lose them.

Step 2: Locate the transaxle fill plug and drain plug

• Find the transaxle on the driver side of the engine bay area (underneath).
• The fill plug is on the side of the transaxle case; the drain plug is at the bottom.
• Both plugs use a 10mm hex bit socket (Allen).

Step 3: Loosen the fill plug first

• Place the drain pan under the transaxle area.
• Use a 10mm hex bit socket (Allen) with a 3/8" ratchet to break the fill plug loose first (do not fully remove yet).
• If it won’t loosen, stop here. You don’t want to drain it and then find you can’t refill it.

Step 4: Drain the old transaxle fluid

• Position the drain pan directly under the drain plug.
• Use the 10mm hex bit socket (Allen) and 3/8" ratchet to remove the drain plug.
• Let it drain until it slows to an occasional drip (usually 10–20 minutes).

Step 5: Reinstall the drain plug with a new crush washer

• Clean the drain plug area using shop rags and a light spray of brake cleaner.
• Install a new drain plug crush washer on the drain plug.
• Thread the drain plug in by hand to avoid cross-threading.
• Use a torque wrench with the 10mm hex bit socket (Allen): Torque to 39 N·m (29 ft-lbs).

Step 6: Fill the transaxle with Toyota ATF WS

• Remove the fill plug fully using the 10mm hex bit socket (Allen) and 3/8" ratchet.
• Install the fluid transfer pump onto a bottle of Toyota ATF WS.
• Pump fluid into the fill hole until it starts to run back out in a steady dribble.
• Wait 30–60 seconds, then pump a little more until it dribbles out again.
• Car must be level for correct fill level.

Step 7: Reinstall the fill plug with a new crush washer

• Install a new fill plug crush washer on the fill plug.
• Thread the fill plug in by hand.
• Use a torque wrench with the 10mm hex bit socket (Allen): Torque to 39 N·m (29 ft-lbs).
• Clean any spilled ATF with brake cleaner and shop rags.

Step 8: Reinstall the under cover

• Reposition the under cover.
• Use the 10mm socket and trim clip removal tool to reinstall all bolts and clips snugly.

Step 9: Lower the car

• Use the floor jack to lift slightly, remove the jack stands, then lower the car to the ground.

✅ After Repair

• Start the car and verify no warning lights.
• With your foot on the brake, shift through P-R-N-D and back to P (pause 2 seconds in each).
• Test drive 10–15 minutes, then park and check underneath for any seepage at the fill/drain plugs.
• Dispose of used ATF properly at a recycling center or parts store that accepts waste fluids.
