They are super super tiny, overall just weaker compared to your "domestic" tranny's.....If any engine could have negative torque it would be a honda engine, its sick, ranges from about 95-145ft lbs....(civic-preludes)...so there was reallly no use in creating a transmission to handle all that torque if its not necessary.........and to even get that much torque out of the engine you have to rev the shit out of it 5-6k plus......
