Solution

1. Preparation

Tools Required:
- Clean lint-free cloth
- Funnel (if necessary for refill)
Ensure the vehicle is parked on a level surface and the engine is running (in park or neutral).

2. Check Transmission Fluid Level

For Models with a Dipstick:
1. Remove the dipstick from the tube.
2. Wipe the dipstick clean with a lint-free cloth.
3. Reinsert the dipstick fully back into the tube.
4. Remove the dipstick again and check the fluid level against the markings on the dipstick.
5. If the fluid is low, add the appropriate transmission fluid through the dipstick tube using a funnel.
For Models without a Dipstick:
1. Locate the fill plug on the side of the transmission casing.
2. Remove the fill plug using the appropriate socket or wrench.
3. Insert a finger into the fill hole; the fluid should be level with the bottom of the hole.
4. If fluid is low, use a funnel to add the correct type of transmission fluid until it begins to trickle out of the fill hole.

3. Reassemble

Reinstall the dipstick or fill plug securely after checking and adjusting the fluid level.
