Solution

1. Preparation

Gather tools and parts for the repair.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to avoid any electrical issues during the repair.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Ensure safety by confirming that the vehicle is stable before working underneath.

3. Remove the Transmission Pan

Place a drain pan under the transmission pan to catch any fluid.
Unscrew and remove the bolts securing the transmission pan (torque specifications may vary; refer to service manual).
Carefully lower the pan and allow any remaining fluid to drain out.

4. Inspect and Replace Gasket/Seal

Remove the old gasket or seal from the transmission pan and the mating surface.
Clean both surfaces thoroughly to ensure a good seal with the new gasket.
Install the new gasket or seal, ensuring it is properly seated.

5. Reinstall the Transmission Pan

Position the transmission pan back onto the transmission.
Hand-tighten the bolts, then use a torque wrench to tighten them to the specified torque (check service manual for exact values).

6. Refill Transmission Fluid

Locate the transmission dipstick tube and use a funnel to pour in the recommended type of transmission fluid.
Check the fluid level after adding; top off as necessary.

7. Lower the Vehicle

Carefully remove the jack stands and lower the vehicle back to the ground.
Reconnect the battery.
