Bought one of those Dorman painted drain pans for a 6R80. I was so disappointed when I pulled it out and saw two scratches on the flange in the paint that cross the gasket. Looks like an = sign. You can catch your fingernail, may be a bit deeper than paint, maybe just the paint, hard to tell.

Wondering if I should send back. Not thrilled about using RTV, but I am also wondering how much the gasket could seal..
I need the truck so I will probably install the stock one.

Use Permatex Spray a Gasket on the pan flange and pans side of the gasket. Either Red or Copper will work and seal forever, yet come off easily at your next change.

Just take a piece of 400 wet and dry and lightly sand the scratches so the is no sharp edge on them, if there is non forget it.
I would use the Lube Locker gasket before RTV. RTV is total **** if you want to remove the pan later.

I'd hit the scratches with some light sand paper, then I'd use the Black RTV that is made for oil pan gaskets. Put a dab in the local area that is scratched and then put the gasket on. You should be good to go!

FWIW I have put on several Chrysler transmission pans with black RTV because most of them don't use gaskets...

just my $0.02
