K.I.S.S. principal works!

I've had ok luck with regular cork gaskets too as long as the pan and trans. were absolutely flat and clean of oil/debris before installation. I also go by the tighten it till ya see it squeeze out a little. But nearly everyone I did eventually seeped a little. Never a big leak that actually left anything on the floor. Just enough seepage to make the case messy. Since I started using the Mopar perf. gasket I haven't had any seepage/leak of any sort. There must have been a mismatch somewhere on yours is the only thing I can think of but glad to hear you got it fixed. Happy motoring!
