Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, transmission fluid gauge.
Ensure the vehicle is parked on a level surface and the engine is turned off. Engage the parking brake.
Disconnect the battery to prevent electrical issues during repair.

2. Inspect and Replace Transmission Fluid

Sub-steps:
1. Remove the transmission drain plug and let the fluid drain into a pan.
2. Inspect the drained fluid for metal shavings or burning smell. Replace with new fluid if necessary.
3. Reinstall the drain plug and torque to manufacturer specifications.
4. Refill the transmission with the correct type of fluid as specified in the owner’s manual.

3. Inspect and Replace Motor Mounts (if damaged)

Sub-steps:
1. Lift the vehicle securely using jack stands.
2. Remove any components obstructing access to the motor mounts.
3. Visually inspect motor mounts for cracks or excessive wear.
4. If damaged, remove the old mounts using a socket set and replace with new ones, torquing to specifications.

4. Check and Tighten Drive Shaft Connections

Sub-steps:
1. Inspect the drive shafts for any signs of play or damage.
2. Use a socket set to check the tightness of the bolts connecting the drive shafts to the transmission and wheels.
3. Tighten any loose connections to manufacturer torque specifications.
