Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface, and engage the parking brake.
Disconnect the negative battery terminal to prevent any electrical shorts.

2. Fluid Change

Tools Required: Socket set, wrench, transmission fluid pump, drain pan.
Sub-steps:
1. Place the drain pan under the transmission pan.
2. Remove the transmission pan bolts using the socket set and gently lower the pan.
3. Allow the old fluid to completely drain into the pan.
4. Replace the transmission pan gasket to prevent leaks.
5. Reinstall the transmission pan and torque the bolts to the manufacturer's specifications (typically around 10 Nm).
6. Fill the transmission with new fluid using a fluid pump until it reaches the proper level according to the dipstick.

3. Replace Transmission Filter

Tools Required: Socket set, wrench, new transmission filter.
Sub-steps:
1. With the transmission pan removed, locate the transmission filter.
2. Remove the filter retaining screws and detach the old filter.
3. Install the new filter, ensuring it is seated correctly.
4. Reinstall the transmission pan as described above.

4. Electrical Inspection

Tools Required: Multimeter.
Sub-steps:
1. Reconnect the negative battery terminal.
2. Use the multimeter to check the voltage at the TCM connector.
3. Inspect wiring for fraying or damage and repair as needed.

5. Test Drive

Take the vehicle for a test drive to ensure the transmission is functioning properly without slipping.
