Solution

1. Preparation

Gather the necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Fluid Change

Sub-steps:
1. Place a drain pan under the transmission pan.
2. Remove the transmission pan bolts using a socket set.
3. Carefully lower the pan and allow the old fluid to drain completely.
4. Inspect the pan for debris and clean it thoroughly.
5. Replace the transmission filter if applicable.
6. Reinstall the transmission pan with a new gasket, tightening bolts to the manufacturer’s specified torque (usually around 8-10 Nm).

3. Fluid Refill

Sub-steps:
1. Use a funnel to add the manufacturer-recommended transmission fluid through the dipstick tube.
2. Start the engine and allow it to reach operating temperature, then shift through all gears.
3. Check the fluid level again and add more fluid if necessary to reach the correct level.

4. Sensor and Software Inspection

Sub-steps:
1. Using the OBD-II scanner, check for software updates or recalls for the transmission control module.
2. If necessary, update the software as per the manufacturer’s instructions.
3. Inspect and replace any faulty sensors (throttle position, speed sensors) as indicated by diagnostic results.
