well heres the story...
i own a 97 sc2 and for sum reason i keep on blowing holes in the tranny..
its a 5 speed and iv been thru 5 transmissions..WHY DO THEY KEEP GOING OUT??
easy fix... stop doing burn outs ........ this is the reason the diff pin comes out. try treaing down the tranny "a good one" and weld the diff pin in as described above and you shouldnt have any more issues..
