Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and is secure.
Disconnect the negative battery terminal.

2. Drain the Transmission Fluid

Place a drain pan under the transmission.
Remove the transmission pan bolts using a socket set.
Carefully lower the transmission pan to avoid spilling fluid; allow fluid to fully drain into the pan.

3. Remove and Inspect the Transmission Pan

Clean the transmission pan thoroughly to remove old gasket material.
Inspect the pan for any damage or wear that may require replacement.

4. Replace Gaskets and Seals

Remove the old gasket from the transmission and clean the surface.
Install a new gasket on the transmission pan.
Examine and replace any damaged seals around the transmission.

5. Reassemble Components

Reattach the transmission pan and tighten the bolts to the manufacturer’s torque specifications (usually around 8-12 ft-lbs).
Reconnect the transmission cooler lines if they were removed.

6. Refill Transmission Fluid

Use a funnel to refill the transmission with the appropriate type of fluid (check owner's manual for specifications).
Start the engine and allow it to run for a few minutes while checking for leaks.

7. Test Drive

After confirming no leaks, take the vehicle for a test drive to ensure smooth transmission operation.
