I think everyone misses the point that this was an ls transmission connected to a said 500hp car. What do we know about ls transmissions? They are the weakest of all b-series transmissions. Thus it isn't unbelievable that you ran through the gears on a used ls transmission and tore it up.

Point being is you're still a stupid Honda fag that wants to cheap out on parts and wonder why shit breaks then try to blame the person that did the work/swap/trade with you.
