Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, fluid pump, funnel, rags
Gather necessary replacement parts such as transmission fluid, filter, and gaskets.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Fluid Change

Step 1: Remove the transmission pan
- Use a socket set to remove the bolts securing the transmission pan.
- Carefully lower the pan and allow the old fluid to drain into a suitable container.
Step 2: Replace the filter
- Remove the old filter from the transmission and discard it.
- Install the new filter according to the manufacturer’s specifications, ensuring it is seated properly.
Step 3: Clean the transmission pan
- Clean the transmission pan and magnet to remove debris and buildup.
- Inspect the pan for cracks or damage and replace if necessary.

3. Reassembly

Step 1: Reinstall the transmission pan
- Place a new gasket on the cleaned transmission pan.
- Secure the pan back onto the transmission with the removed bolts, tightening them to the manufacturer's torque specifications.
Step 2: Fill with new transmission fluid
- Use a fluid pump and funnel to refill the transmission with the correct type and amount of fluid as specified in the owner’s manual.
- Start the engine and allow it to reach operating temperature.

4. Test Drive

Take the vehicle for a test drive, monitoring for any signs of jerking or abnormal shifting.
If issues persist, further diagnosis may be required.
