Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked on a flat surface and the engine is warm (operating temperature).

2. Accessing the Transmission Dipstick or Fill Plug

Tools Required: Socket set, funnel (if adding fluid).
If your model has a dipstick, locate it near the back of the engine bay.
If it has no dipstick, locate the transmission fill plug on the side of the transmission.

3. Checking the Fluid Level

For Dipstick:
- Pull the dipstick out and wipe it clean with a lint-free cloth.
- Reinsert the dipstick fully and pull it out again to check the level against the marked indicators.
- If the level is low, add the appropriate transmission fluid through the dipstick tube using a funnel.
For Fill Plug:
- Remove the fill plug using a socket wrench.
- Insert a finger into the hole; fluid should be just below the edge. If fluid drips out, the level is adequate.
- If fluid is low, add the correct type of transmission fluid through the fill hole using a funnel until it begins to flow out.

4. Reassemble

Replace the dipstick or fill plug securely.
Ensure there are no leaks around the fill plug area if it was removed.
