Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a level surface and engage the parking brake.
Allow the engine to cool before beginning work.

2. Change Transmission Fluid

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Place a drain pan under the transmission pan.
3. Remove the transmission pan bolts using a socket set.
4. Carefully lower the pan and allow old fluid to drain completely.
5. Inspect the pan for metal shavings or debris.
6. Replace the transmission filter, if applicable, and ensure it is seated properly.
7. Clean the transmission pan and replace the gasket.
8. Reinstall the transmission pan and torque the bolts to manufacturer specifications (typically around 10-12 ft-lbs).

3. Refill Transmission Fluid

Sub-steps:
1. Use a funnel to add new transmission fluid through the dipstick tube (check owner's manual for correct fluid type, usually Toyota ATF WS).
2. Start the engine and let it idle for a few minutes while checking for leaks.
3. Shift through all gears with the brake applied to circulate the fluid.
4. Recheck the fluid level and add more if necessary.
