Solution

1. Preparation

Gather necessary tools and materials.
Tools Required:
- Funnel
- Clean cloths
- Torque wrench (if required for fill plug)
Ensure the vehicle is parked on a flat surface and the engine is warmed up to normal operating temperature.

2. Check Fluid Level

Using a Dipstick (if applicable):
1. Remove the dipstick from the transmission housing.
2. Clean the dipstick with a lint-free cloth and reinsert it completely.
3. Remove it again to check the fluid level against the markings.
Using Fill Plug (if no dipstick):
1. Locate the fill plug on the transmission case, typically near the top.
2. Use a wrench to carefully remove the fill plug.
3. Insert a finger or a suitable tool into the fill hole to check if fluid is present. Fluid should be level with the bottom of the fill hole.

3. Add Transmission Fluid (if needed)

If the fluid is low, use a funnel to add the manufacturer-recommended transmission fluid through the dipstick tube or fill hole.
Add fluid in small increments, checking level frequently to avoid overfilling.
Replace the dipstick or fill plug securely once finished.
