Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, OBD-II scanner.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Raise the vehicle using a jack and secure it on jack stands.
2. Locate the transmission dipstick or fill plug.
3. Remove the dipstick or fill plug and check fluid level.
4. If low, drain the old transmission fluid using a pan and replace it with new fluid (consult owner’s manual for the correct type).
5. Reinsert the dipstick or fill plug and torque to manufacturer specifications (typically around 15-20 Nm).

3. Inspect and Replace Engine/Transmission Mounts

Sub-steps:
1. Locate the engine and transmission mounts (usually near the gearbox).
2. Visually inspect for cracks, tears, or excessive wear.
3. If damaged, remove the bolts securing the mounts using a socket wrench.
4. Replace with new mounts and torque bolts to manufacturer specifications.
5. Ensure proper alignment before securing.

4. Inspect the CV Joints and Driveshaft

Sub-steps:
1. Examine CV joints for torn boots or excessive play.
2. If damaged, remove the axle assembly by unbolting it from the hub and transmission.
3. Replace with new CV joint or axle assembly as needed.
4. Reinstall the assembly and torque fasteners to manufacturer specifications.
