Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to prevent any electrical issues.

2. Drain Transmission Fluid

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

3. Inspect and Replace Components

Inspect the Gasket:
- Remove the old gasket from the transmission pan and the transmission housing. Clean the surfaces thoroughly.
Inspect the Seals:
- Check the input and output shaft seals for leaks.
- If damaged, use a seal puller to remove and replace seals.
Replace the Filter:
- If applicable, remove the transmission filter and replace it with a new one.

4. Reinstall Transmission Pan

Place a new gasket onto the transmission pan.
Secure the transmission pan back onto the transmission using the original bolts. Torque the bolts to the manufacturer's specifications (typically around 12-15 ft-lbs).

5. Refill Transmission Fluid

Use a funnel to refill the transmission with the correct type and amount of transmission fluid (refer to the owner's manual for specifications).
Start the engine and let it run for a few minutes, then check the fluid level again and add more if necessary.
