Solution

1. Preparation

Gather tools and safety equipment: gloves, safety glasses, container for fluid, and rags.
Ensure the vehicle is parked on a level surface and the engine is off.
Safety Warning: Allow the engine to cool before working on the transmission.

2. Locate the Leak Source

Use a flashlight to examine the transmission pan and surrounding components.
Clean any excess fluid from the area with rags to better identify the leak source.

3. Replace Damaged Seals or Gaskets

If the transmission pan gasket is leaking:
1. Drain the transmission fluid into a container by removing the drain plug (if equipped).
2. Remove the transmission pan bolts using a socket set.
3. Carefully lower the pan and remove the old gasket.
4. Clean the mating surfaces on the transmission and pan.
5. Install a new gasket and reattach the pan, tightening bolts to the manufacturer’s specified torque (check the service manual for the exact value).
If the seals on the transmission cooler lines are leaking:
1. Disconnect the lines using the appropriate wrench.
2. Replace any worn or damaged seals.
3. Reconnect the lines securely.

4. Refill Transmission Fluid

Use the appropriate type of transmission fluid as specified in the owner’s manual.
Refill the transmission through the dipstick tube or fill plug until the proper level is reached.

5. Test the Repair

Start the engine and let it run for a few minutes.
Shift through all gears, allowing the fluid to circulate.
Check for any leaks around the repaired area.
