Solution

1. Preparation

Gather tools and materials, including a new transmission fluid filter (if applicable), fresh transmission fluid, and cleaning materials.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent accidental electrical shorts.

2. Drain Old Transmission Fluid

Locate the transmission drain plug and place a drain pan underneath.
Remove the drain plug using the appropriate socket, allowing the old fluid to completely drain.
Inspect the magnetic drain plug for metal shavings or debris, indicating internal wear.

3. Replace Transmission Filter (if applicable)

Remove the transmission pan bolts and carefully take off the pan.
Remove the old transmission filter and install the new filter, ensuring it is seated properly.
Clean the transmission pan and magnet before reinstallation.

4. Refill with New Transmission Fluid

Replace the transmission pan and tighten the bolts to the manufacturer's torque specifications to avoid leaks.
Using a funnel, refill the transmission with the recommended type and amount of new transmission fluid through the dipstick tube.
Start the engine and let it idle, cycling through all gear positions to circulate the new fluid.

5. Check Fluid Levels

With the engine running, check the transmission fluid level using the dipstick.
Add fluid as necessary to reach the correct level.
