Big hole in my tranny!? HELP!

[Ryans99LS1]

Well guys i went to the track last night and i thought everything went great. I ran 13.1 all night and beat all the new ls2 gto's there. But... when i got home i did my usual check and there was tranny fluid leaking all over the ground.. i drove it home, it ran fine. Ran it 6 times down the track, it ran perfect. The tranny was so stong all night. Well once i saw the fluid i got the flashlight out and there is a hole about 2inches in diameter in the bottom of the tranny more on the drivers side though The tranny cant be blown, it was working fine and made no weird noises. I can see right in there and look at my flywheel. You cant see it from the passanger side. Im thinking there was some kind of plug or covering there that came lose and fell out? Help me out guys im stuck. Its not a stock tranny either, its a stage 3.

Any insight at all would be helpful. Ill post pictures by tomorrow at the latest.

ok well i found out that i was missing the 2 inspection hole covers and replaced those but also learned that if im leaking from those then i have a problem. Its either my front seal is blown or the pump is bad. Also my tranny could be generating too much pressure and thats not good. If my tranny is creating too much pressure, how do i fix that?

The front seal is already being replaced so ill find out about the pump soon.
