Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Allow the engine to cool down before beginning work.
Tools Required: Socket set, funnel, transmission fluid, torque wrench, OBD-II scanner.

2. Check Transmission Fluid

Remove the transmission dipstick and wipe it clean.
Reinsert the dipstick and remove it again to check the fluid level.
If the fluid is low, add the appropriate type of transmission fluid as specified in the owner's manual.
Inspect the fluid for any burning smell or dark coloration; if present, a fluid change may be necessary.

3. Address Fluid Leaks

If any leaks are found, identify the source of the leak (e.g., seals, gaskets).
Replace any damaged seals or gaskets as needed.
Clean any residual fluid from the area to monitor for future leaks.

4. Replace Transmission Filter

Remove the transmission pan using a socket wrench, allowing fluid to drain into a container.
Replace the old transmission filter with a new one, ensuring proper alignment and secure fit.
Reinstall the transmission pan and tighten the bolts to the manufacturer’s specified torque.

5. Refill Transmission Fluid

After reassembling, refill the transmission with the correct type and amount of fluid using a funnel.
Start the engine and let it run for a few minutes, then check the fluid level again and top off as necessary.
