Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is on a flat surface and securely supported with jack stands.
Disconnect the battery to avoid electrical issues.

2. Drain Transmission Fluid

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

3. Replace Gasket or Seals

Clean the transmission pan and the mating surface on the transmission using a gasket scraper.
If the gasket is damaged, remove it completely and replace it with a new one (make sure to apply gasket maker if required by the vehicle's specifications).
Check the input and output shaft seals for wear; replace them if necessary.

4. Reassemble Transmission Pan

Reinstall the transmission pan using a torque wrench to tighten the bolts to the manufacturer's specified torque (typically around 12-15 ft-lbs).
Ensure the gasket is properly seated to prevent future leaks.

5. Refill Transmission Fluid

Using a funnel, refill the transmission with the appropriate type and amount of transmission fluid (check the owner's manual for specifications).
Start the engine and let it run for a few minutes, then shift through all gears to circulate fluid.

6. Check for Leaks

Inspect the area around the transmission pan and seals for any signs of leakage after refilling.
If no leaks are present, reconnect the battery.
