Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical shorts.

2. Transmission Fluid Change

Sub-steps:
1. Remove the transmission drain plug using a socket wrench and allow the fluid to drain completely into a suitable container.
2. Replace the drain plug with a new gasket and torque to the manufacturer's specifications (typically around 20-25 ft-lbs).
3. Remove the transmission fill plug and pour in new transmission fluid (ensure it meets Toyota specifications, typically ATF WS) using a funnel.
4. Check fluid level using the dipstick (if applicable) and ensure it is within the marked range.

3. Inspect and Replace Transmission Filter

Sub-steps:
1. Remove the transmission pan using a socket set and discard the old gasket.
2. Remove the old transmission filter; clean the mounting surface.
3. Install the new transmission filter, ensuring it is seated properly.
4. Replace the transmission pan with a new gasket and torque the bolts to the manufacturer's specifications (typically around 12-15 ft-lbs).

4. Check and Replace Transmission Mounts (if necessary)

Sub-steps:
1. Lift the vehicle securely on jack stands.
2. Inspect the transmission mounts for cracks or excessive wear.
3. Remove the bolts securing the damaged mount and replace it with a new one.
4. Torque the new mount bolts to manufacturer's specifications.

5. Reconnect Battery and Test Drive

Reconnect the battery, ensuring all connections are secure.
Start the engine and let it idle for a few minutes.
Perform a test drive, monitoring for any shuddering or abnormal behavior.
