5-Step Guide for Replacing the Old Transmission Pan
If you have a lowered vehicle, the chassis and the transmission are more prone to scraping and denting since they are closer to the ground. The transmission pan is in charge of keeping your transmission from damage. It also keeps the transmission fluid from leaking. So once you've noticed that your transmission slips when you shift into gear, or there is a constant pool of transmission fluid whenever you park your car, then your transmission pan might be leaking due to a crack or a worn-out gasket. Replacing the pan, however, is an easy task. Here's a guide on how to install a new transmission pan.

Needed tools and materials
Removing the old transmission pan
Drain the transmission fluid from the pan. Remove the pan from the transmission by unscrewing the gaskets. Keep the screws in a safe place for reassembly later.
Preparing to install the pan
Scrape the surface of the pan using a razor scraper. Make sure that there is no gasket material. Apply a thin bead of oil soluble grease around the top of the pan to prevent the gasket from moving once you install the pan.
Installing the transmission pan
Place the replacement pan to the transmission and bolt them into place using your hands. This is to prevent the bolts to be loose or overly tightened, which may result in leaks. You may retighten them using a socket wrench to seal the pan entirely.
Putting transmission fluid
At the engine compartment, look for the transmission fluid dipstick. It is usually labeled or red in color, and is located at the back portion of the compartment. Pull it out of the tube and then use a funnel to pour the required amount of transmission fluid into it. Now, clean the dipstick with a cloth and replace it into the tube.
Testing the car
Now that your transmission pan is replaced, start the car and keep it on for five to ten minutes. Shift the car from "Park" to the "Low 1" position and back. Check the transmission fluid if it needs to be refilled.
Tips and warnings
- Replace the gaskets or o-rings once you've noticed cracks or other signs of wearing out. This will prevent leaking and loosening of the pan.
- Dispose the old transmission fluid carefully.
