Pump Slide Spring
Part No. 77722-01K

Package Quantity: 5

Sonnax now offers a high performance pump slide spring 77722-01K for the 4L60, 4L60-E, 4L65-E and 200-4R. In high performance applications, when engine speed exceeds 5800 rpm, the centrifugal force on the pump vanes acts to center the pump slide and reduce the pump volume. In high performance applications it is critical to maintain maximum pump volume in order to hold line pressure and avoid 3-4 clutch failure. The Sonnax spring is stiffer than the combined force ofthe dual OE springs and is able to hold the pump slide in a maximum volume position despite the high engine speed.
