Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is on a level surface and securely lifted using jack stands.
Disconnect the battery to prevent electrical issues.

2. Drain Transmission Fluid

Remove the transmission drain plug using a socket set.
Allow the fluid to fully drain into a suitable container.

3. Inspect and Replace Gaskets/Seals

Transmission Pan Gasket:
- Remove the transmission pan bolts with a socket.
- Carefully detach the pan and remove the old gasket.
- Clean the mating surfaces of the pan and transmission.
- Install a new gasket and reattach the pan, torquing bolts to the manufacturer’s specifications (generally around 10-12 ft-lbs).
Seals:
- Identify and replace any worn or damaged seals around the input/output shafts and transmission cooler lines.

4. Replace Transmission Fluid

Reinstall the drain plug and torque to specifications.
Fill the transmission with the correct type and amount of fluid (consult owner's manual for specifications).
Start the engine and allow it to reach operating temperature.

5. Check for Leaks

After filling, inspect the transmission and surrounding areas for any new signs of leakage.
Take the vehicle for a short test drive and recheck fluid levels.
