Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery before starting work on the electrical systems.

2. Transmission Fluid Change

Drain the Transmission Fluid
- Locate the transmission drain plug and remove it using a socket wrench.
- Allow fluid to completely drain into a catch pan.
Replace Transmission Filter
- Remove the transmission pan by unscrewing the bolts.
- Carefully detach the pan; clean the surface and remove the old gasket.
- Replace the old filter with a new one, ensuring it fits securely.
Reassemble the Transmission Pan
- Apply a new gasket or RTV sealant to the pan surface.
- Reattach the transmission pan, tightening bolts to the manufacturer's specified torque (typically around 10-12 ft-lbs).
Refill Transmission Fluid
- Reinstall the drain plug.
- Use a funnel to add the appropriate type and amount of transmission fluid (typically Toyota Type T-IV or equivalent, consult the owner’s manual for capacity).

3. Inspect and Replace Transmission Mounts (if necessary)

Remove the Old Transmission Mounts
- Lift the vehicle securely using jack stands.
- Locate the transmission mounts and remove the bolts using a socket set.
- Inspect for cracks or wear; replace if necessary.
Install New Transmission Mounts
- Position the new mounts in place and secure them with bolts.
- Ensure the mounts are tightened to the manufacturer's torque specifications.
