Solution

1. Preparation

Gather tools: socket set, torque wrench, OBD-II scanner, fluid pump, jack stands, and safety goggles.
Ensure the vehicle is on a level surface and securely elevated on jack stands.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick or fill plug.
2. Remove the dipstick or fill plug to check the fluid level.
3. If the fluid is low or dirty, use a fluid pump to extract old fluid from the transmission.
4. Replace with manufacturer-recommended transmission fluid, ensuring proper fill level.
5. Reinstall the dipstick or fill plug securely.

3. Replace Damaged Transmission Mounts

Sub-steps:
1. Locate the transmission mounts; typically found at the rear and sides of the transmission.
2. Remove the bolts securing the mounts using the socket set.
3. Replace any damaged mounts with new OEM parts.
4. Torque the mount bolts to the manufacturer’s specifications.

4. Repair or Replace CV Joints/Drive Shafts

Sub-steps:
1. Inspect the CV joints for torn boots or excessive play.
2. If damaged, remove the wheel and axle nut, then disconnect the CV joint from the transmission.
3. If necessary, replace the CV joint or entire drive shaft assembly.
4. Reassemble by reversing the removal steps, ensuring all fasteners are torqued to specifications.
