CAUTION: Be sure the pump bore area is well cleaned. It is a hidden debris trap. Flow from the pump goes into the manual valve circuit, then passes into the EPC circuit. Pump pressure at this point is very high. Any debris not cleaned out here will be pumped through the transaxle on the first operation.
