Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a level surface and safely supported with jack stands if needed.
Disconnect the battery to prevent any electrical issues while working.

2. Inspect and Replace Seals

Remove the Transmission Pan
- Use a socket set to remove the bolts holding the transmission pan.
- Carefully lower the pan to avoid spilling fluid; use a drain pan to catch any fluid.
Inspect the Gasket and Seals
- Examine the transmission pan gasket and any other seals for wear or damage.
- Clean the surface of the transmission case and the pan with a suitable solvent.
Replace the Gasket/Seals
- Install a new transmission pan gasket or any damaged seals.
- Ensure the gasket is seated properly and aligned with the bolt holes.

3. Reassemble

Reinstall the Transmission Pan
- Position the pan back onto the transmission and hand-tighten the bolts.
- Use a torque wrench to tighten the bolts to the manufacturer’s specifications (usually around 8-12 lb-ft, but check the service manual for exact values).

4. Refill Transmission Fluid

Add Fluid
- Using a funnel, refill the transmission with the recommended type of fluid through the dipstick tube.
- Check the level using the dipstick to ensure it is within the proper range.

5. Final Checks

Reconnect the battery.
Start the vehicle and let it run for a few minutes.
Shift through all gears to circulate the fluid and check for any leaks.
