Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.
Allow the vehicle to cool down before starting work.

2. Fluid Change

Step 2.1: Drain the old transmission fluid
- Locate the transmission drain plug and remove it using a socket set.
- Allow fluid to completely drain into a suitable container.
Step 2.2: Replace the transmission filter (if applicable)
- Remove the transmission pan by unscrewing all bolts using a socket set.
- Carefully detach the old filter and install the new one.
- Clean the pan thoroughly and replace the pan gasket before reattaching.
Step 2.3: Refill with new transmission fluid
- Replace the drain plug once all fluid has drained.
- Use a funnel to fill the transmission with the recommended type and volume of new fluid (typically WS ATF for this model).

3. Inspect and Replace Transmission Mounts

Step 3.1: Remove the old mounts
- Secure the vehicle on jack stands and remove any components obstructing access to the transmission mounts.
- Use a socket set to unbolt and remove the old mounts.
Step 3.2: Install new mounts
- Position the new mounts in place and bolt them down to the chassis and transmission, ensuring they are tightened to the manufacturer's torque specifications.

4. Adjust Transmission Linkage

Step 4.1: Check alignment
- Inspect the transmission linkage for misalignment or wear.
Step 4.2: Adjust linkage if necessary
- Adjust the linkage as needed to ensure it engages properly without excessive play.
