Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and securely lift it with jack stands.
Disconnect the negative battery terminal to avoid electrical issues.

2. Drain Transmission Fluid

Place a drain pan under the transmission pan.
Remove the transmission pan bolts using a socket set (typically 10mm).
Carefully lower the pan to drain the fluid, ensuring to catch all fluid.

3. Replace Transmission Pan Gasket

Clean the mating surfaces of the transmission and the pan with a scraper and solvent.
Inspect the pan for dents or damage; replace if necessary.
Apply a thin bead of RTV silicone or install a new gasket around the pan edge.
Reattach the pan using the original bolts and torque them to specification (usually 10-12 ft-lbs).

4. Inspect and Replace Seals

Examine the transmission cooler lines and fittings for wear; replace any damaged lines or seals.
If applicable, replace the output shaft seal by removing the drive shaft, using a seal puller, and installing a new seal.

5. Refill Transmission Fluid

Using a funnel, refill the transmission with the manufacturer-recommended fluid (consult the owner's manual for specifications).
Start the engine and let it idle while checking for leaks around the pan and lines.

6. Final Checks

Reconnect the negative battery terminal.
Test drive the vehicle to ensure proper operation and monitor for any leaks.
