Please see and earlier question and answer re: Where is the transmission dipstick on 1990 Honda Accord LX. It may answer your question. By the way, answer is: The dipstick is located at front of transmission, next to the engine block. There is NO TUBE and the dipstick is small - look crefully! Hank.
