Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the battery to ensure safety during electrical work.

2. Addressing Transmission Issues

Check Fluid Levels:
- Remove the transmission dipstick and wipe it clean; reinsert and remove to check fluid level.
- If low, add the manufacturer-recommended transmission fluid until the correct level is achieved.
Replace Transmission Fluid:
- Raise the vehicle securely on jack stands.
- Locate the transmission pan, remove bolts, and allow old fluid to drain into a catch pan.
- Replace the transmission filter if applicable and reinstall the pan with a new gasket.
- Refill with new transmission fluid according to specifications.

3. Fixing Electrical Issues

Battery and Alternator Check:
- Use a multimeter to test the battery voltage (should read around 12.6 volts).
- Start the engine and recheck the voltage; it should rise to around 13.7 to 14.7 volts.
- If readings are outside the normal range, replace the faulty component (battery or alternator).

4. Engine Performance Repair

Inspect and Replace Spark Plugs:
- Remove the ignition coil or cover to access the spark plugs.
- Use a spark plug socket to remove old spark plugs and inspect for wear or carbon buildup.
- Replace with new OEM spark plugs, ensuring they are gapped correctly.

5. Final Assembly

Reconnect the battery and ensure all tools are removed from the engine bay.
Start the engine and check for leaks or unusual noises.
