Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and set the parking brake.
Disconnect the battery to prevent electrical issues.

2. Drain Transmission Fluid

Place a drain pan underneath 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 Clean

Examine the transmission pan for metal shavings or debris; clean the pan thoroughly.
Inspect the filter (if applicable) and replace it if necessary.
Clean the sealing surface on the transmission and the pan.

4. Replace Seals and Gaskets

Remove any old gasket material from the pan and transmission surface.
Replace the transmission pan gasket and any worn seals.
Ensure that all surfaces are clean and free from debris.

5. 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 manufacturer specifications (typically around 10-12 ft-lbs).
Reconnect the battery.

6. Fill Transmission Fluid

Using a funnel, refill the transmission with the correct type of fluid specified in the owner's manual.
Start the engine and let it idle, then shift through all gears to circulate fluid.
