Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is on a level surface and the engine is off.
Wear safety gloves and goggles.

2. Drain Old Transmission Fluid

Tools Required: Drain pan, wrench set
Locate the transmission drain plug under the vehicle.
Use a wrench to remove the drain plug and allow the old fluid to fully drain into the drain pan.
Replace the drain plug and tighten it to the manufacturer’s torque specifications (usually around 15-20 lb-ft).

3. Replace Transmission Filter

Tools Required: Socket set, screwdriver
Remove the transmission pan using a socket wrench.
Carefully take out the old transmission filter.
Install the new transmission filter, ensuring it fits snugly and securely.

4. Add New Transmission Fluid

Tools Required: Funnel, new transmission fluid
Locate the transmission fill tube and remove the cap.
Using a funnel, pour in the appropriate type and amount of new transmission fluid (check owner's manual for specifications).
Start the engine and let it idle for a few minutes.

5. Check Fluid Level

With the engine running, shift through all gears and return to "Park."
Recheck the fluid level using the dipstick and add more fluid if necessary.
Ensure the fluid is at the proper level and has a bright red color with no burnt smell.
