Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the negative battery terminal to prevent any electrical issues.

2. Check and Replace Transmission Fluid

Locate the Transmission Dipstick: Remove the dipstick and check fluid level.
Fluid Quality Inspection: Inspect the fluid color and smell; it should be a bright red color and not burnt.
Drain Old Fluid: Place a drain pan under the transmission pan, remove the drain plug, and allow the fluid to fully drain.
Replace Filter: Remove the transmission pan, replace the old filter, and clean the pan thoroughly.
Add New Fluid: Reinstall the pan with a new gasket, torque the bolts to the manufacturer's specifications (typically around 10-15 ft-lbs), and refill with the recommended transmission fluid type (usually Toyota ATF WS).

3. Inspect and Replace Torque Converter (if necessary)

Access the Torque Converter: This may require removing the transmission from the engine.
Inspect the Torque Converter: Check for signs of wear or damage; if damaged, it must be replaced.
Reinstall the Torque Converter: Follow the manufacturer’s guidelines for installation, ensuring it locks into place properly.

4. Replace Transmission Mounts (if worn)

Locate the Mounts: Identify the transmission mounts under the vehicle.
Remove the Old Mounts: Support the transmission, remove the bolts securing the mounts, and take out the old mounts.
Install New Mounts: Position the new mounts in place, secure them with bolts, and torque to specifications.
