Installed this last weekend

I even installed a drain plug in the stamped pan but the rubber gasket with the stamped pan didn't seal. Leaked like the Titanic. I also use the plastic dip around the shift cables (65 transmission) as they would tend to drip when sitting a while. Now that I have posted this, I expect red fluid on my drip pan tonight. :( :rolleyes:
Once the stamped pan has been distorted it is hard for them to reseal. You won't have any issues with the cast one you got.
