Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to prevent accidental electrical shorts.

2. Raise Vehicle

Use a jack to lift the vehicle and secure it on jack stands.
Ensure the vehicle is stable before proceeding.

Check the transmission pan for leaks; if the gasket is damaged, proceed to replace it.
If leaks are found in the cooler lines, identify whether they need repair or replacement.

4. Replace Transmission Pan Gasket (if applicable)

Remove the bolts securing the transmission pan using a socket wrench.
Carefully lower the pan and discard the old gasket.
Clean the mating surface on the transmission and the pan.
Place a new gasket on the pan, ensuring proper alignment.
Reinstall the pan and tighten the bolts to the manufacturer’s specified torque, typically around 10-12 ft-lbs.

5. Repair or Replace Cooler Lines (if applicable)

If any cooler lines are damaged, remove the fittings using an appropriate wrench.
Replace with new lines, ensuring all connections are tight to prevent leaks.

6. Refill Transmission Fluid

Reconnect the battery.
