Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked on a flat, stable surface and the engine is turned off.

2. Inspect and Clean

Tools Required: Clean rags, flashlight, and possibly a socket set.
Clean the area around the transmission pan and seals to remove any dirt or accumulated debris.
Use a flashlight to examine the cleaned area for any signs of leaks or damage.

3. Replace Seals or Gaskets (if leaks are found)

Tools Required: Socket set, torque wrench, gasket scraper, new transmission fluid.
Drain the transmission fluid by removing the drain plug or tilting the vehicle to allow fluid to flow out.
Remove the transmission pan by unscrewing the bolts carefully.
Replace damaged seals or gaskets with new ones. Ensure the surfaces are clean before installing new gaskets.
Reattach the transmission pan and torque the bolts to manufacturer specifications (typically around 10-15 Nm).
Refill with the correct type and amount of transmission fluid as specified in the owner's manual.

4. Test for Leaks

Start the engine and allow it to reach normal operating temperature.
Shift through all gears while monitoring the transmission area for any signs of leakage.
Check the fluid level again and top off if necessary.
