Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, OBD-II scanner, safety goggles, gloves.
Ensure the vehicle is on a level surface and secure it with jack stands after lifting.

2. Inspect and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick or filler plug.
2. Remove the dipstick, wipe it clean, and reinsert to check fluid level.
3. If low or dirty, drain the transmission fluid using a drain pan.
4. Replace with the manufacturer-recommended transmission fluid (e.g., Mercon LV for Ford).
5. Recheck the fluid level after refilling.

3. Inspect Drivetrain Components

Sub-steps:
1. Visually inspect the driveshaft for any signs of wear or imbalance.
2. Check the universal joints for play or damage.
3. Inspect the differential for leaks or abnormal wear.
4. If damaged components are found, replace them as necessary.

4. Replace Engine Mounts (if necessary)

Sub-steps:
1. Support the engine using an engine hoist or jack with a wooden block.
2. Remove the bolts securing the engine mounts to the engine block and frame.
3. Replace with new engine mounts (OEM recommended).
4. Torque the bolts to the manufacturer’s specifications (consult repair manual).
