Solution

1. Preparation

Gather tools and materials: socket set, torque wrench, transmission fluid, clean rags.
Safely lift the vehicle using a jack and secure with jack stands.
Allow the engine to cool before working on the transmission.

2. Drain Transmission Fluid

Position a drain pan under the transmission pan.
Remove the transmission pan bolts using the socket set and carefully lower the pan.
Allow the fluid to completely drain into the pan.

3. Inspect and Replace Gasket

Remove the old gasket from the transmission pan and the transmission housing.
Clean the mating surfaces on both the pan and the transmission housing using a scraper and clean rags.
Inspect the pan for any bends or damage; replace if necessary.

4. Install New Gasket and Reassemble

Place the new gasket onto the transmission pan.
Reinstall the transmission pan and tighten the bolts to the manufacturer’s specified torque (typically around 10-12 ft-lbs).
Ensure that the pan is seated evenly without pinching the gasket.

5. Refill Transmission Fluid

Locate the transmission dipstick tube and use a funnel to add new transmission fluid.
Start with the recommended type and amount of fluid, checking the owner’s manual for specifics (typically around 6-8 quarts for a full refill).
Start the engine and allow it to run for a few minutes while cycling through the gears to distribute the fluid.

6. Check for Leaks

With the vehicle still running, visually inspect the area around the transmission pan and lines for any signs of leaks.
If no leaks are present, lower the vehicle and perform a final check on the fluid level, adding more if necessary.
