Solution

1. Preparation

Tools Required: Socket set, wrench set, transmission jack, drain pan, funnel.
Safely elevate the vehicle on jack stands to access the transmission.
Ensure the engine is cool before starting repairs.

2. Drain Transmission Fluid

Place a drain pan under the transmission pan.
Remove the transmission pan bolts using the socket set and carefully lower the pan to drain fluid.
Inspect the fluid for metal shavings or burnt smell, which could indicate internal damage.

3. Replace Gasket and Seal

Clean the transmission pan and the surface on the transmission where the pan mounts.
Replace the old gasket with a new one, ensuring the surface is free of debris.
If any seals (e.g., input/output shaft seals) are leaking, remove and replace them accordingly.

4. Reinstall Transmission Pan

Position the transmission pan back onto the transmission.
Hand-tighten the bolts in a crisscross pattern to ensure even pressure, then torque to the manufacturer’s specification (usually around 10-12 ft-lbs).
Refill the transmission with the appropriate type of fluid (consult owner's manual for specifications).

5. Test for Leaks

Start the engine and let it idle while checking for leaks around the transmission pan and seals.
Shift through all gears while monitoring fluid levels, adding fluid as necessary until it reaches the proper level.
