🔧 Transmission Fluid - Drain and Refill

Your Camry uses a sealed-style automatic transmission with Toyota WS fluid. The safe DIY service is a drain and refill, not a power flush. This helps refresh the fluid while keeping the transmission fill level correct.

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

⚠️ Safety & Precautions

• Work with the vehicle level. Fluid level changes if the car is tilted.
• Transmission fluid can be hot. Let the vehicle cool before draining.
• Use only Toyota WS fluid.
• Do not overfill. The final level must be checked at the correct fluid temperature.
• A scan tool or fluid temperature readout is strongly recommended for accurate fill level.
• Battery disconnect is not required for this service.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Warm the transmission slightly

• Drive the vehicle for 10-15 minutes so the fluid flows easily.
• Do not make it fully hot. Warm is enough.
• Warm fluid drains faster.

Step 2: Raise and level the vehicle

• Use the floor jack and support the Camry with jack stands.
• Keep the vehicle as level as possible front to rear and side to side.

Step 3: Remove the under cover

• Use a 10mm socket to remove the lower splash shield fasteners.
• Set the cover and fasteners aside in order.

Step 4: Drain the old fluid

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

Step 5: Refill with new WS fluid

• Remove the fill/overflow plug using the 24mm socket.
• Use the fluid transfer pump to add Toyota WS fluid through the fill hole.
• Add fluid until it just begins to dribble out of the fill opening.
• Install a new fill plug gasket.
• Snug the fill plug for now. Final level check comes next.

Step 6: Set the final fluid level

• Start the engine and keep it idling.
• Move the shifter slowly through each gear position, then back to Park.
• Use the scan tool to watch transmission fluid temperature.
• At the correct level check range, remove the fill/overflow plug again with the 24mm socket.
• If fluid dribbles out, the level is correct.
• If no fluid comes out, add WS fluid with the fluid transfer pump until it just drips out.
• Reinstall the plug and Torque to 39 Nm (29 ft-lbs).
• Level checks must be done carefully.

Step 7: Reinstall the under cover

• Use the 10mm socket to reinstall the splash shield.
• Make sure all clips and bolts are secure.
