Review on Enhanced SEO: GM Genuine Parts 24224781 Automatic Transmission Fluid Pan Gasket by Mirzet Gosselin

Used this gasket when changing the transmission oil filter on my 2013 suburb. Good quality works great. To remove the pan, loosen the exhaust system mounting bolts. A PB jet spray and a long extension with an impact wrench worked well. You don't have to remove the screws. Then you can use a long pry bar to apply some pressure to the exhaust pipe to remove the sump. First watch the YouTube video.
