Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery to prevent electrical shorts.

2. Check and Top Off Transmission Fluid

Sub-steps:
- Remove the transmission fluid dipstick and wipe it clean.
- Reinsert the dipstick and pull it out again to check the fluid level.
- If low, add the recommended transmission fluid (typically Toyota ATF WS).
- Check for any signs of metal shavings or burnt smell in the fluid.

3. Inspect and Replace Transmission Mounts

Tools Required: Socket set, torque wrench, pry bar
Sub-steps:
- Locate the transmission mounts and inspect for cracks or excessive wear.
- Using a socket set, remove the bolts securing the mounts to the vehicle frame.
- Carefully support the transmission with a jack and remove the old mounts.
- Install new mounts and torque bolts to the manufacturer’s specifications (typically around 50-60 ft-lbs).

4. Inspect Drive Shafts and Universal Joints

Sub-steps:
- Lift the vehicle securely using a jack and jack stands.
- Visually inspect the drive shafts and universal joints for any visible damage or excessive play.
- If damaged, replace the affected components and ensure proper alignment during installation.

5. Adjust Shift Linkage

Sub-steps:
- Locate the shift linkage assembly and inspect it for proper alignment.
- If misaligned, adjust the linkage to ensure smooth operation.
- Test the shifting mechanism to confirm the adjustment resolved the issue.
