(7) Filter element
(8) Housing
(9) Inlet passage Oil from the torque converter outlet relief valve flows to torque converter screen (1).Oil flows through inlet passage (9). The oil fills the space between the inside of housing (8) and element (7). During normal operation, the oil flows through element (7). The oil then passes through outlet passage (4) to the remainder of the hydraulic system. Element (7) stops any debris that is in the oil.If the filter elements become full of debris, the restriction to the flow of oil causes a pressure increase inside the filter. The pressure oil causes bypass switch (3) to move against the force of spring (2).The oil then flows past the open bypass switch to the remainder of the hydraulic system. When the oil does not go through the filter element, the debris in the oil will cause damage to other components in the hydraulic system.Correct maintenance must be used in order to ensure that element (7) does not become full of debris. This would stop the flow of clean oil to the hydraulic system.
