u can fix it.... i know a guy who cracked his ls trans and put a 1/8 inch hole in like 3 years ago... he tig welded the case after he took everything out of it and rebuilt it, he jsut took his time and tigged the hole up working from the bottom of the hole(like inside the trans and then out) its held up for 3 years of thrashing the hell out of it w/ close to 300 at the wheels thru turbo so yea it can be done
