Umm..... What?

No I didn't tighten the bolts to spec. I haven't got the tranny out if the car yet so I'm not exactly sure. I was just wondering about the converter bolt holes leaking.

If you didn't torque the bolts to spec, it might not have punched through the cover. unless the bolts used were really long. The cover is about 3/16" thick. I've seen the inside of converters, and while I've seen the cover dimpled inside from too long a bolt, I never saw one that had gone through. If possible air check the converter to see exactly where the leak might be. As others have mentioned, it could be the pump seal has been damaged when you installed the converter.
