First full pass when I put a hemi in my car. We were at a msca event in Canada and broke a ring gear and exploded trans. parts went all the way to grand stands. took an hour clean up the mess then the tow truck when putting the car on blew a hyd. line and dumped fluid again on track and it took another hour to clean up. the other racers where not happy!!! when I went to work on he car later I took the rest of trans out of car without a wrench.
