Solution

1. Preparation

Gather tools and parts for the repair.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick and remove it to check fluid level.
2. If fluid is low or discolored, drain the old fluid using a transmission drain plug.
3. Replace with the manufacturer-recommended transmission fluid.
4. Reinstall the drain plug and refill the transmission through the dipstick tube.
5. Start the engine and cycle through the gears to circulate the fluid, then recheck the level.

3. Inspect and Replace Transmission Mounts

Sub-steps:
1. Safely lift the vehicle using jack stands.
2. Locate the transmission mounts and visually inspect for cracks or excessive wear.
3. Remove the bolts securing the defective mounts using a socket set.
4. Install new mounts by aligning them properly and tightening to the manufacturer's torque specifications.
5. Lower the vehicle back to the ground.

4. Inspect CV Joints and Axles

Sub-steps:
1. Lift the vehicle and secure with jack stands.
2. Remove the front wheels for easier access to the CV joints.
3. Inspect CV boots for tears or leaks; replace them if necessary.
4. Check the CV joints for play and signs of wear; replace the entire axle if any issues are found.
5. Reinstall wheels and lower the vehicle.
