Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Ensure the vehicle is on a level surface and secure it with wheel chocks.

2. Inspect and Replace Engine/Transmission Mounts

Remove Underbody Shield (if equipped):
- Use a socket set to remove bolts securing the underbody shield.
Support the Engine/Transmission:
- Use a jack with a wooden block to support the engine/transmission assembly.
Remove Old Mounts:
- Use a socket set to remove the bolts securing the engine and transmission mounts.
- Carefully remove the old mounts and inspect for excessive wear or damage.
Install New Mounts:
- Position the new mounts in place.
- Torque the mount bolts to the manufacturer’s specifications (typically around 45-55 ft-lbs; check service manual for exact value).

3. Transmission Fluid Change

Drain Old Fluid:
- Place a drain pan under the transmission pan.
- Remove the transmission pan bolts and carefully lower the pan to drain fluid.
Replace Filter (if applicable):
- Remove the old filter and install the new filter.
Reinstall Transmission Pan:
- Clean the pan and apply a new gasket or sealant.
- Torque the pan bolts to manufacturer specifications (check service manual).
Refill Transmission Fluid:
- Use the appropriate transmission fluid (typically Toyota ATF WS) and refill through the dipstick tube.
