Product Details
Sonnax now offers a High Performance pump slide spring 77722-01K for the 200-4R, 700-R4, 4L60 and 4L60-E. 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 200-4R, 4L60 and 4L60-E applications it is critical to maintain maximum pump volume in order to hold line pressure and avoid 3-4 clutch failure. The Sonnax spring 77722-01K is stiffer than the combined force of the dual OEM springs and is able to hold the pump slide in a maximum volume position despite the high engine speed.
