Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, wrench set, funnel, new transmission fluid, and replacement filter.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to avoid electrical issues during repairs.

2. Fluid Inspection and Replacement

Check Fluid Level:
- Remove the dipstick and wipe it clean.
- Reinsert and remove the dipstick again to check fluid level.
Drain Old Fluid:
- Place a drain pan under the transmission pan.
- Remove the transmission pan bolts using a socket wrench.
- Carefully lower the pan and allow the fluid to drain completely.

3. Filter Replacement

Remove Old Filter:
- Locate the transmission filter, typically found inside the pan.
- Unclip or remove any retaining screws and slide out the old filter.
Install New Filter:
- Position the new filter into place and secure it according to manufacturer specifications.

4. Reassemble Transmission Pan

Clean and Reattach Pan:
- Clean the transmission pan and the gasket surface.
- Apply a new gasket or sealant as necessary.
- Position the pan back and tighten the bolts to the manufacturer's torque specifications.

5. Refill Transmission Fluid

Using a funnel, add the appropriate type and amount of transmission fluid through the dipstick tube.
Start the engine and let it run for a few minutes, then check the fluid level again, adding more if needed.
