(10) Housing The transmission charging hydraulic filter is fastened to the outside part of the main frame. The transmission charging hydraulic filter is located near the fuel tank behind the front wheel. Oil from the torque converter sump goes to the gear pump for the torque converter and for the transmission. The transmission charge pump section sends oil through inlet line (2) to the transmission charging hydraulic filter.Oil goes through inlet passage (6). The oil fills the space between the inside of housing (10) and element (9). During normal operation, the oil goes through element (9) to outlet passage (5). The oil exits through outlet line (1). Outlet line (1) divides the oil. Some of the oil goes to the lockup clutch and synchronizing valve. The remainder of the oil flows to the transmission hydraulic control. Element (9) stops any debris that is in the oil.If the filter element becomes full of debris, the restriction to the flow of oil causes a pressure increase inside the filter. The pressure increase causes bypass valve (4) to move against the force of spring (8). The oil then goes past the open bypass valve to the remainder of the hydraulic system. When the oil does not go through the filter element, the debris that is in the oil will cause damage to other components in the hydraulic system.Correct maintenance must be used in order to be certain that element (9) does not become full of debris. If the element is full of debris, the flow of clean oil to the hydraulic system will be stopped.
