Solution

1. Preparation

Gather needed tools and parts. Ensure the vehicle is parked on a level surface.
Disconnect the battery to prevent any electrical issues during repair.

2. Check and Change Transmission Fluid

Remove Transmission Drain Plug:
- Use a socket set to remove the drain plug and allow the old fluid to drain into a pan.
Inspect Fluid:
- Check the fluid for metal shavings or burnt smell; this indicates internal damage.
Replace Fluid:
- Reinstall the drain plug and refill with new transmission fluid (use Toyota WS fluid, as specified).
- Use a funnel to add fluid through the dipstick tube until the proper level is reached.

3. Replace Transmission Filter

Remove Transmission Pan:
- Unbolt the transmission pan using a socket set and carefully remove it.
- Clean the pan and magnet inside to remove debris.
Replace Filter:
- Remove the old filter and install the new filter, ensuring it is securely fastened.
Reinstall Pan:
- Apply a new gasket or sealant and reinstall the transmission pan, tightening bolts to the manufacturer’s torque specifications.

4. Inspect and Replace Mounts (if necessary)

Identify Mount Locations:
- Locate the engine and transmission mounts.
Inspect for Damage:
- Check for cracks or excessive wear.
Replace Damaged Mounts:
- Unbolt the damaged mounts and replace them with new ones, ensuring proper alignment.
