Solution

1. Preparation

Tools Required:
- Socket set
- Transmission fluid pump
- Drain pan
- Funnel
- OBD-II scanner (for diagnostics)
Safety Warnings:
- Ensure the vehicle is on a level surface.
- Engage the parking brake and use wheel chocks.

2. Drain Transmission Fluid

Locate the transmission drain plug under the vehicle.
Place a drain pan beneath the transmission pan.
Using the appropriate socket, remove the drain plug and allow the old transmission fluid to completely drain into the pan.
Clean the drain plug and inspect for any metal shavings or debris.

3. Replace Transmission Filter (if applicable)

Remove the transmission pan if your RAV4 model requires a filter replacement.
Detach the old filter and replace it with a new one, ensuring it is properly seated.
Clean the transmission pan and the magnet inside (if equipped) to remove any sediment.

4. Reinstall Components

Reinstall the drain plug and torque it to the manufacturer’s specifications (typically around 30 ft-lbs).
If removed, reattach the transmission pan using a new gasket and torque the bolts to the specified amount (usually around 12 ft-lbs).

5. Fill New Transmission Fluid

Locate the transmission fluid fill port (usually on the top of the transmission).
Using a funnel, fill the transmission with the appropriate type of fluid as specified in the owner’s manual (typically Toyota ATF WS).
Carefully monitor the fluid level using the dipstick, adding fluid until it reaches the correct level.

6. Cycle the Transmission

Start the engine and let it idle for a few minutes.
Move the gear selector through all gears (P, R, N, D) and back to park to circulate the new fluid.
Recheck the fluid level and top off as necessary.
