Solution

1. Preparation

Tools Required:
- Rags or paper towels for cleaning
- Flashlight for visibility
- OBD-II scanner (if warning lights are present)
Park the vehicle on a flat surface and ensure the engine is off.
Gather necessary tools and personal protective equipment (PPE).

2. Inspect Under the Vehicle

Look for signs of fluid pooling beneath the transmission area.
Use a flashlight to inspect tight spaces and confirm the source of the leak.

3. Check Transmission Fluid Level

Locate the transmission dipstick; remove it and wipe it clean with a rag.
Reinsert the dipstick, then remove it again to check the fluid level.
If the fluid is low, note the color and smell for further assessment.

4. Identify and Repair Leaks

If leaks are found:
- Tighten bolts on the transmission pan (if applicable) to prevent leaks.
- Replace any damaged seals or gaskets, using a socket set to remove the pan if necessary.
- If lines are damaged, replace them as needed.
Follow manufacturer torque specifications when reassembling components.

5. Refill Transmission Fluid (if applicable)

If fluid levels were low, refill with the manufacturer-recommended transmission fluid type.
Use a funnel to avoid spills and check fluid levels again after filling.
