Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Gather the necessary tools and parts.
Safety: Allow the engine to cool before beginning work.

2. Drain Transmission Fluid

Tools Required: Socket set, drain pan, funnel
Place the drain pan under the transmission pan.
Remove the transmission pan bolts using the socket set.
Carefully lower the pan and allow the old fluid to drain completely.

3. Inspect and Clean

Inspect the transmission pan for any metal shavings or debris.
Clean the transmission pan and magnet (if equipped) thoroughly to remove any contaminants.
Inspect the old gasket for damage; replace if necessary.

4. Replace Seals and Gasket

Tools Required: Gasket scraper, torque wrench
Remove the old gasket from the transmission pan and surface.
Install a new gasket (or apply gasket maker if required) onto the pan.
Replace any damaged seals around the transmission housing.

5. Reassemble Transmission Pan

Reattach the transmission pan to the transmission housing.
Tighten the bolts to the manufacturer's specified torque settings in a crisscross pattern to ensure even sealing.

6. Refill Transmission Fluid

Using a funnel, refill the transmission with the appropriate type and amount of fluid as specified in the owner's manual.
Start the engine and let it idle, checking for leaks around the pan and seals.
