Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Safety warning: Allow the engine to cool before starting the repair.

2. Drain Transmission Fluid

Place a drain pan under the transmission pan.
Remove the transmission pan bolts with a socket set.
Carefully lower the pan and allow the remaining fluid to drain completely.

3. Inspect and Replace Gasket/Seals

Check the pan gasket for signs of damage and replace it if necessary.
Inspect the input and output shaft seals for leaks; replace them if they are worn.
Clean the transmission pan and mating surfaces thoroughly.

4. Reinstall Transmission Pan

Apply a bead of sealant (if applicable) along the edge of the pan.
Position the transmission pan back into place and secure it with bolts.
Torque the bolts to the manufacturer's specifications (usually around 8-10 ft-lbs).

5. Refill Transmission Fluid

Use a funnel to refill the transmission with the appropriate type of fluid (consult owner's manual for specifications).
Start the engine and let it run for a few minutes, cycling through all gears.

6. Check for Leaks

With the engine running, observe the transmission area for any signs of leaking fluid.
If no leaks are present, proceed to test drive the vehicle.
