Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Socket set
- Torque wrench
- OBD-II scanner
- Screwdrivers
Ensure the vehicle is on a flat surface and securely elevated if necessary. Disconnect the negative battery terminal for safety.

2. Inspect and Replace Transmission Fluid

Check the transmission fluid level using the dipstick.
If low or dirty, drain the old fluid by removing the drain plug.
Replace with manufacturer-recommended transmission fluid (e.g., Toyota ATF WS).
Refill to the proper level and check for leaks after sealing.

3. Inspect Transmission Mount

Locate the transmission mount and visually inspect for cracks or excessive wear.
If damaged, remove the bolts securing the mount using a socket set.
Replace with a new mount, ensuring it is properly aligned.
Torque the bolts to the manufacturer’s specifications.

4. Adjust or Replace Linkage/Cables

Inspect the shift linkage or cables for any signs of wear or misalignment.
If necessary, adjust the linkage according to the service manual.
Replace any worn or damaged cables to ensure proper shifting action.
