Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent electrical issues during work.

2. Drain Transmission Fluid

Place a drain pan under the transmission pan.
Remove the transmission pan bolts using a socket wrench (ensure to keep track of bolt locations).
Carefully lower the pan and allow the fluid to drain completely.

3. Inspect and Replace Seals/Gaskets

Remove the old gasket and clean the mating surfaces on the transmission and the pan.
Inspect the transmission filter; replace if necessary.
Replace any worn seals (input shaft seal, output shaft seal) as identified during the diagnostic steps.

4. Reinstall Transmission Pan

Apply a thin layer of RTV gasket maker to the pan side.
Position the new gasket and reinstall the pan, tightening the bolts to manufacturer's specifications (typically 10-12 ft-lbs).

5. Refill Transmission Fluid

Reconnect the battery.
Use a funnel to refill the transmission with new fluid (consult the owner's manual for the exact type and capacity).
Start the engine and let it run for a few minutes, checking for leaks around the pan and seals.

6. Test Drive

Take the vehicle for a short test drive to ensure proper shifting and operation.
Recheck the fluid level after the test drive and add fluid if necessary.
