Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a level surface and engage the parking brake.
Tools required:
- Socket set
- Transmission fluid pump
- Torque wrench
- Catch pan
- OBD-II scanner

2. Drain Old Transmission Fluid

Place a catch pan under the transmission drain plug.
Remove the drain plug using the socket set and allow the old fluid to completely drain.
Inspect the drain plug for metal shavings or debris indicating internal wear.

3. Replace Transmission Filter (if applicable)

Remove the transmission pan bolts with the socket set.
Carefully detach the transmission pan and replace the filter, ensuring proper alignment.
Clean the mating surfaces of the transmission pan and the transmission housing.

4. Refill with New Transmission Fluid

Use the transmission fluid pump to fill the system with the manufacturer-recommended transmission fluid (typically Toyota ATF WS).
Fill until the fluid reaches the appropriate level on the dipstick while the engine is running and the transmission is in 'Park'.

5. Check for Leaks

Reattach the drain plug and ensure it is torqued to the manufacturer specifications.
Start the vehicle and let it idle, checking for any leaks around the transmission pan and drain plug.
