Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical issues.

2. Drain Transmission Fluid

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

3. Inspect and Replace Gasket/Seals

Inspect the transmission pan gasket for wear or damage; replace if necessary.
Check the transmission input and output shaft seals for leaks; replace if needed.
Clean the mating surfaces of the transmission and pan thoroughly.

4. Install New Transmission Pan and Fluid

Apply a new gasket to the transmission pan, ensuring proper alignment.
Reattach the transmission pan using the specified torque value (usually around 10-12 Nm).
Refill the transmission with the recommended fluid type as per manufacturer specifications (usually Dexron III or a similar fluid).

5. Test for Leaks

Reconnect the battery.
Start the vehicle and allow it to reach operating temperature.
Check under the vehicle for any signs of leaks around the transmission pan and seals.
