    I ordered a GM filter for the transmission. It came with two gaskets, a paper coated and a cork gasket. Paper is for a continuous raised rib oil pan, cork for non continuous. These are for the stock stamped steel pans. I'm running a cast aluminum deep pan with a smooth face surface all the way around. So, would the paper or cork be better in my application, and is any type sealant recommended? Thanks

    I don't like any sealer in the auto trans. gaskets, and I'd use cork on that pan.

    Forget the gasket and use "The Right Stuff"!

    It will seal it good but taking the pan off in the future may require a hammer and chisel. ;)

    Seriously... I would use the cork gasket since the pan has a smooth surface.

    ^Good Tip!

    Clean both surfaces with brake cleaner.
    A little bit of "tack" to keep the gasket situated during assembly and torque the bolts to spec. (9 ft/lbs)

    Personally... I will use a "LubeLocker" gasket on my transmission pan the next time I do a fluid/filter change.

    With a cast pan and these gaskets... The pan should NEVER leak.
    I just need a cast pan for my 200-4R and they are over $200. :(
