Solution

1. Preparation

Gather necessary tools: clean cloth, funnel, and possibly a transmission fluid pump.
Ensure the vehicle is parked on a level surface and the engine is warm.

2. Locate the Transmission Dipstick/Filler Plug

For models with a dipstick:
1. Open the hood and secure it.
2. Locate the transmission dipstick, typically marked with a bright color.
For models without a dipstick:
1. Locate the filler plug on the transmission case, usually located on the side.

3. Check Fluid Level

For models with a dipstick:
1. Pull the dipstick out and wipe it clean with a cloth.
2. Reinsert the dipstick fully and remove it again to check the fluid level.
3. The fluid should be within the marked range on the dipstick.
For models without a dipstick:
1. Remove the filler plug using the appropriate socket.
2. Insert a clean finger into the hole; the fluid level should be at the bottom of the opening.
3. If fluid drips out, it indicates a full level.

4. Add Transmission Fluid (if necessary)

If the fluid level is low, use a funnel to add the recommended transmission fluid type (check owner’s manual for specification).
Pour in small amounts, checking the level frequently to avoid overfilling.
Replace the dipstick or filler plug securely.
