Solution

1. Preparation

Gather tools and parts: OBD-II scanner, socket set, torque wrench, transmission fluid, transmission filter, and a new gasket.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical shorts.

2. Fluid Change

a. Drain Old Fluid
- Locate the transmission drain plug and use a socket set to remove it.
- Allow the old fluid to completely drain into a suitable container.
b. Replace Filter
- Remove the transmission pan using a socket set.
- Replace the old filter with a new one, ensuring it is seated correctly.
- Clean the transmission pan and replace the gasket.
c. Fill New Fluid
- Reinstall the transmission pan and torque the bolts to the manufacturer's specifications.
- Using a funnel, refill the transmission with the appropriate type and amount of new fluid as specified in the owner’s manual.

3. Electrical Inspection

Inspect the wiring harness connected to the TCM for signs of wear or damage.
If necessary, replace any damaged connectors or wires.

4. TCM Reprogramming (if applicable)

Use the OBD-II scanner to clear any error codes and perform a transmission adaptation procedure as per the vehicle’s service manual.

5. Reconnect Battery

Reconnect the battery and ensure all connections are secure.
