Solution

1. Preparation

Gather necessary tools: a clean lint-free cloth for wiping the dipstick.
Ensure the vehicle is on a level surface and the engine is warmed up.
Wear gloves to protect your hands from oil and dirt.

2. Check Fluid Level

Dipstick Removal
- Carefully pull out the transmission dipstick.
- Wipe the dipstick clean with the lint-free cloth to remove any fluid.
Fluid Level Inspection
- Reinsert the dipstick fully back into the tube, then remove it again.
- Observe the fluid level against the marked indicators on the dipstick (Full/Low).
- If the fluid level is low, take note of this for a possible fluid top-up.
Fluid Condition Assessment
- Examine the fluid color: it should be bright red; brown or black indicates degradation.
- Smell the fluid; burnt smell signifies overheating or contamination.
- If the fluid is discolored or smells burnt, consider a fluid replacement.

3. Fluid Top-Up (if needed)

Locate Fill Port
- Identify the transmission fill port near the dipstick.
Add Transmission Fluid
- Use a funnel and pour the appropriate type of ATF (Automatic Transmission Fluid) as specified in the owner's manual.
- Add fluid slowly and check the level frequently to avoid overfilling.
Final Check
- Recheck the fluid level to ensure it is within the proper range.
- Replace the dipstick securely once finished.
