Performance Automatic has added two new “Pro Pumps” to its line of transmissions and components. The new pumps are designed to be used with AOD and 4R70W transmissions.
The company checks for proper pump bushing centerline and examines the pump gear pocket to ensure it has the correct depth. The stator housing is reconditioned and machined for a thrust bearing, eliminating the plastic washer that may fail due to excessive rpm, said the company. Modified stator rings are installed, as well as a new pump O-ring and gasket.
The Pro Pumps are direct replacement parts that come complete with a roller bearing. They’re suitable for any rebuild, according to Performance Automatic.
The PA53436 AOD Pro Pump will fit all AOD transmissions up to 1993. The PA45436 AODE/4R70W Pro Pump will fit all AODE and 4R70W transmissions from 1994-2004.
