I removed the upper pump housing, impeller and plate but am not able to remove the lower plastic pump housing which houses the drive shaft seals I tried pressuring the lower unit to 17 inch pounds with no results. The shift shaft housing came out with pressure previously, but the pump housing doesn't budge.
