well, if the mileage of ur car wud ve been 40k plus kms i wud ve suggested u to get the ATF( auto tranny fluid) changed, but i dont think there shud be any problem at just 16k kms, well, get it checked frm honda guys n if the problem remainds, get the oil changed, who knows, may be due to some reasons its causing the problem.and yes there is a filter in the tranny near the engine but it shudnt choke so early.
