Abstract
An oil suction device for an automatic transmission includes: an oil pan that receives oil supplied to various portions of the automatic transmission and returned to the oil pan and reserves the received oil therein; an oil strainer located over the oil pan; a suction port drawing in the oil reserved in the oil pan; and an elastic wall provided selectively between a portion of the oil pan that receives a relatively small amount of the oil returned to the oil pan and the suction port, the elastic wall extending from a bottom surface of the oil pan and reaching a lower surface of the oil strainer to interrupt a flow of oil.
