(1) Bypass valve
(2) Filter cartridge The oil filter for the transmission can be mounted directly on the rear of the transmission. Also, the filter base may be remotely mounted to the vehicle. If the option for a remote filter is utilized, a set of hoses will connect the filter base to the filter inlet and outlet ports on the rear of the transmission.Oil flows from the transmission pump through the oil filter. This action ensures that contamination is removed from the oil before the oil enters the system components.Bypass valve (1) is connected in parallel to the oil filter. If the oil filter becomes blocked, the pressure between the pump and the filter will rise. This increased pressure opens a flow path through the bypass valve to the system components. Movement of the bypass valve moves a switch which sends a signal to the ECM. The ECM illuminates an indicator in the cab which informs the operator that the oil filter is blocked.
