Solution

1. Preparation

Gather tools and materials: socket set, torque wrench, transmission fluid, rags, and a transmission pan gasket.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical issues.

2. Remove Transmission Pan

Place a drain pan under the transmission to catch fluid.
Unscrew the bolts securing the transmission pan and carefully lower it.
Clean the surface of the transmission where the pan was attached.

3. Inspect and Replace Gasket/Seals

Check the old gasket for damage; if it’s worn or cracked, replace it.
Inspect the transmission output shaft seal and input shaft seal for leaks and replace if necessary.

4. Reinstall Transmission Pan

Position the new gasket on the transmission pan.
Reattach the pan to the transmission, tightening the bolts to the manufacturer's specified torque (generally around 12-15 ft-lbs, but verify in the service manual).
Reconnect the battery.

5. Refilling Transmission Fluid

Use a funnel to pour the recommended transmission fluid (check owner’s manual for type) into the dipstick tube.
Start the engine and allow it to idle; check the fluid level with the dipstick and add fluid as necessary.
