Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, transmission fluid dipstick, multimeter, torque wrench.
Disconnect the negative battery terminal to prevent electrical shorts while working.

2. Transmission Fluid Inspection

Sub-steps:
1. Remove the transmission dipstick and wipe it clean.
2. Reinsert the dipstick and pull it out again to check fluid level. Ensure it is within the recommended range.
3. Inspect the fluid color; if it is dark or has a burnt smell, consider a fluid change.

3. Replace Transmission Fluid (if necessary)

Sub-steps:
1. Raise the vehicle securely on jack stands.
2. Remove the transmission pan bolts and allow old fluid to drain into a pan.
3. Replace the transmission filter if applicable.
4. Reinstall the transmission pan with a new gasket and torque bolts to manufacturer specifications.
5. Refill with new transmission fluid through the dipstick tube, using the recommended type.

4. Inspect and Replace Engine Mounts (if damaged)

Sub-steps:
1. Use a jack to support the engine slightly.
2. Remove the bolts securing the engine mount to the engine and frame.
3. Replace the old mount with a new one, ensuring proper alignment.
4. Torque the mount bolts to manufacturer specifications.

5. Check Spark Plugs and Ignition Coils

Sub-steps:
1. Remove the ignition coils using a socket wrench.
2. Inspect the spark plugs for wear; replace them if they are worn.
3. Test the ignition coils with a multimeter to ensure they are within specifications.
4. Reinstall the ignition coils and secure them properly.
