Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure with jack stands.
Disconnect the battery to avoid electrical issues while working.

2. Remove Transmission Pan

Use a socket set to remove the bolts securing the transmission pan.
Carefully lower the pan and drain the existing fluid into a catch container.
Clean the mating surface on the transmission with a lint-free cloth.

3. Inspect and Replace Gaskets

Inspect the old gasket for wear or damage.
Install a new transmission pan gasket, ensuring it is properly aligned.
Torque the pan bolts to manufacturer's specifications (typically around 12-15 ft-lbs).

4. Refill Transmission Fluid

Reattach the transmission pan and check that all bolts are secure.
Use a funnel to refill the transmission with the appropriate type of fluid (check the owner's manual for specifications).
Start the vehicle and let it idle, then shift through all gears to circulate the fluid.

5. Check for Leaks

Inspect the area around the transmission pan and lines for any signs of leaking.
Recheck the fluid level and add more if necessary.
