Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, transmission fluid pump.
Ensure the vehicle is on a level surface and securely lifted using jack stands.
Disconnect the battery before working on electrical systems.

2. Transmission Fluid Change

Sub-steps:
1. Remove the transmission fluid drain plug and drain the old fluid into a suitable container.
2. Replace the drain plug and tighten to the specified torque (refer to the service manual for torque specifications).
3. Remove the transmission fluid dipstick and use a pump to fill with new transmission fluid until the correct level is reached (consult the owner's manual for the correct fluid type).
4. Start the engine and allow it to warm up, then cycle through the gears to distribute the fluid.

3. Inspect & Replace Transmission Mounts

Sub-steps:
1. Remove the necessary components to gain access to the transmission mounts.
2. Visually inspect the mounts for cracks or excessive wear.
3. If damaged, remove the old mounts using a socket set and install new mounts, ensuring they are torqued to specifications.

4. Drivetrain Inspection and Repair

Sub-steps:
1. Inspect the driveshaft and CV joints for any signs of damage or play.
2. Replace any worn or damaged components as needed.
3. Reassemble any components that were removed for access, ensuring all fasteners are tightened to specifications.
