(1) Filter base (2) Outlet line (3) Inlet line (4) Filter housingFilter base (1) for the transmission oil filter is located remotely on the frame.Oil from the torque converter housing flows to the transmission section of the gear pump. The gear pump sends oil to the transmission oil filter.Oil flows through inlet line (3). The oil fills the space between the inside of housing (4) and the element. During normal operation, the oil flows through the element and out outlet line (2) to the transmission hydraulic control and to the lockup clutch solenoid valve. The element stops any debris that is in the oil.If the element becomes full of debris, the restriction to the flow of oil cause a pressure increase inside the housing. The pressurized oil activates bypass switch (3) and an alarm will be registered in the cab.The oil then flows past the open bypass valve and to the transmission hydraulic control. When the oil does not flow through the element, the debris in the oil will cause damage to other components in the transmission system.Use correct maintenance in order to make sure that the element does not become full of debris. If the element is full of debris, the flow of clean oil to the transmission system is stopped.
