Solution

1. Preparation

Gather Tools and Parts: Ensure you have all necessary tools and replacement parts.
Safety Precautions: Disconnect the battery before starting work on the vehicle to prevent electrical issues.

2. Drain Transmission Fluid

Place a drain pan underneath the transmission pan.
Remove the transmission pan bolts using a socket set.
Carefully lower the pan and allow the fluid to drain completely.

3. Replace Seals and Gaskets

Remove Old Gasket: Clean the surface of the transmission pan and remove the old gasket material using a scraper.
Install New Gasket: Place a new gasket on the transmission pan, ensuring it is aligned properly.

4. Inspect and Replace Components

Check Seals: Inspect the input and output shaft seals; if damaged, remove the old seals using a seal puller.
Install New Seals: Lubricate the new seals with transmission fluid and install them using a seal installer or by carefully pressing them into place.

5. Reassemble Transmission Pan

Position the transmission pan back onto the transmission.
Tighten the bolts to the manufacturer's specified torque (typically between 8-12 ft-lbs) in a crisscross pattern to ensure even sealing.

6. Refill Transmission Fluid

Using a funnel, refill the transmission with the appropriate type of fluid (consult the owner's manual for specifications).
Start the engine and allow it to reach operating temperature, then check the fluid level again and add as necessary.
