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. It's critical to maintain maximum pump volume in these vehicles in order to hold line pressure and avoid 3-4 clutch failure. The Sonnax spring is stiffer than the combined force of the dual OE springs and is able to hold the pump slide in a maximum volume position despite the high engine speed.

Designed specifically for high RPM Conditions
Keeps pump in high volume position at high RPM
Replaces 2 OE springs
