Abstract
A clutch pressure modifier valve for an automatic control circuit for a power transmission mechanism in a vehicle driveline wherein provision is made during ratio changes that requires engagement of a fluid pressure operated transmission clutch for modifying a clutch engagement pressure to compensate for the effect of centrifugal pressure build up in the pressure chamber of the clutch structure due to rotation of the clutch at high speeds during a shift interval whereby the timing of the clutch engagement is relatively independent of the rotary speed of the clutch during engagement and whereby the torque capacity of the clutch more closely matches the torque requirements of the driveline during ratio changes.
