Solution

1. Preparation

Gather Tools and Safety Equipment: Ensure you have an OBD-II scanner, basic hand tools (socket set, wrenches), and safety gear (gloves, safety glasses).
Disconnect the Battery: Disconnect the negative terminal of the battery to prevent electrical shorts while working.

2. Fluid Change

Drain Transmission Fluid:
- Locate the transmission drain plug and place a drain pan underneath.
- Remove the drain plug and allow fluid to completely drain.
Replace Fluid Filter (if applicable):
- Remove the transmission pan (if applicable) to access the filter.
- Replace the old filter with a new one, ensuring the sealing surface is clean.
Refill Transmission Fluid:
- Replace the drain plug with a new washer if necessary.
- Use a funnel to refill the transmission with the recommended fluid type, checking the owner's manual for the exact specifications.

3. Electrical Component Inspection

Inspect and Clean Connectors:
- Remove and inspect the connectors for the transmission control module and solenoids.
- Clean any corrosion and reassemble securely.
Test Transmission Solenoids:
- Use a multimeter to test the resistance of the solenoids as per the specifications in the service manual.
- Replace any faulty solenoids as needed.

4. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and check for any warning lights.
Conduct a test drive to ensure that the transmission operates smoothly.
