Solution

1. Preparation

Gather the necessary tools and parts.
Ensure the vehicle is on a level surface and secure it with jack stands if needed.
Disconnect the battery to prevent any electrical issues during repair.

2. Change Transmission Fluid and Filter

Tools Required: Socket set, torque wrench, transmission fluid pump, drain pan, funnel.
Remove the transmission pan by loosening the bolts with a socket wrench.
Allow the old fluid to drain completely into a drain pan.
Replace the transmission filter as per the manufacturer's specifications.
Reinstall the transmission pan, ensuring a new gasket is used, and torque the bolts to the specified value (check manufacturer specs for torque settings).
Refill the transmission with the appropriate type of fluid as specified in the owner's manual using a funnel.

3. Repair or Replace Faulty Components

If diagnostic steps indicated issues with wiring or the TCM:
- Inspect and repair any damaged wiring or connectors.
- If TCM is faulty, remove it from its mounting location and disconnect the electrical connectors.
- Install a new TCM by connecting it to the wiring harness and securing it in place.

4. Reconnect Battery and Clear Codes

Reconnect the battery.
Use the OBD-II scanner to clear any stored fault codes from the system.
Ensure that the system is reset and ready for testing.
