Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, transmission fluid pump.
Safety Warnings: Ensure the vehicle is on a level surface and the parking brake is engaged. Disconnect the battery before working on electrical components.

2. Address Error Codes

Connect the OBD-II scanner and retrieve any error codes related to the transmission.
Document the codes for further analysis and research potential fixes based on the codes received.

3. Fluid Change

Tools Required: Transmission fluid, fluid pump, drain pan.
Remove the transmission pan bolts using a socket set.
Carefully lower the transmission pan and drain the old fluid into a drain pan.
Clean the pan and replace the filter if applicable.
Refill with the appropriate type and amount of new transmission fluid using a fluid pump.

4. Repair Leaks

Identify the source of any leaks found during inspection.
Replace any damaged seals or gaskets, ensuring to clean the mating surfaces before installation.
Torque the transmission pan bolts to the manufacturer’s specified settings.

5. Update TCM Software
