Solution

1. Preparation

Gather tools and materials: funnel, new transmission fluid (consult owner’s manual for the correct type), rags, and a socket set.
Ensure the vehicle is on a level surface and the engine is off.

Depending on the model, either locate the dipstick or the fill plug.
If using a fill plug, remove it with the appropriate socket.

3. Add Transmission Fluid

Using a funnel, add the recommended transmission fluid slowly until it reaches the appropriate level.
- Check fluid level frequently to avoid overfilling.
If the fluid was dirty or burned, consider draining and replacing the entire fluid.

4. Inspect for Leaks

After adding fluid, run the engine and cycle through the gears.
Inspect for any leaks around the fill plug and transmission seals.

5. Finalize

Replace the fill plug securely.
Clean any spilled fluid and dispose of old fluid properly if drained.
