Quick Overview

SONNAX SERVO RELEASE CHECK VALVE 77701-076

Details

Technicians would like to find a way to successfully extend the life of 3-4 clutches, and improve
the 2-3 shift feel. They have been trying, with limited success, since the 700-R4 transmission was
first introduced. Inadequate metering of 2nd gear band servo release oil causes 3-4 clutch failure.
The 3-4 clutch and 2nd gear band are not properly synchronized. Sonnax has now developed a
unique solution that combines an orifice with a ball check valve and solves these problems.
