Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and securely raised with jack stands.
Wear safety gloves and goggles.

2. Drain Old Transmission Fluid

Tools Required: Socket set, drain pan, funnel
Place a drain pan under the transmission pan.
Remove the transmission drain plug (if equipped) or the transmission pan bolts.
Allow the 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)

Tools Required: Socket set, gasket scraper, new filter kit
Remove the transmission pan completely if a filter replacement is necessary.
Carefully remove the old filter and discard it.
Install the new filter, ensuring it is seated correctly.
Clean the transmission pan and remove any old gasket material.

4. Reinstall Transmission Pan

Tools Required: Socket set, torque wrench
Place a new gasket on the transmission pan, aligning it with the bolt holes.
Reinstall the transmission pan and tighten the bolts to the manufacturer-specified torque values (usually around 7-9 ft-lbs).
Reinstall the drain plug and ensure it is secure.

5. Refill Transmission Fluid

Tools Required: Funnel
Use a funnel to pour the new transmission fluid through the dipstick tube.
Refer to the owner's manual for the correct type and quantity of transmission fluid (typically Toyota Genuine ATF WS).
Start the engine and allow it to warm up, then cycle through the gears to circulate the fluid.

6. Check Fluid Level

With the engine running and the transmission in park, check the fluid level using the dipstick.
Add fluid as necessary to reach the proper level.
