Solution

1. Preparation

Tools Required: OBD-II scanner, jack and jack stands, socket set, torque wrench, fluid catch pan
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent any electrical shorts during repairs.

2. Inspect and Replace Transmission Fluid

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Place a fluid catch pan under the transmission pan.
3. Remove the transmission fluid drain plug and allow fluid to fully drain.
4. Inspect the drained fluid for metal shavings or burning smell.
5. Replace the drain plug and refill the transmission with manufacturer-recommended fluid to the proper level using a funnel.

3. Replace Damaged Mounts

Sub-steps:
1. Inspect engine and transmission mounts visually; look for cracks or excessive wear.
2. To replace the mounts, loosen the bolts securing the mounts to the frame and engine/transmission.
3. Remove the damaged mount and replace it with a new one.
4. Torque the bolts to the manufacturer’s specifications.
5. Recheck alignment of the transmission and ensure proper fitment of the mount.

4. Inspect and Replace Driveshaft or CV Joints (If Necessary)

Sub-steps:
1. Remove the wheels for easier access to the CV joints.
2. Inspect the CV boots for tears; replace any damaged boots and repack with grease.
3. If the CV joint is damaged, remove the retaining clips and bolts securing the joint, and replace with a new CV joint.
4. Reinstall the driveshaft, ensuring proper torque on all bolts.
