Abstract: A method is provided for the control of servo hydraulic pressure in an automatic transmission. Servo hydraulic pressure is adapted to engage or release first and second frictional engagement elements arranged in such a relationship that, upon shifting from one particular speed stage to another, one of the first and second frictional engagement elements is released while the other is engaged. The servo hydraulic pressure, engaging one frictional engagement element, is linearly lowered in a torque phase during a shift so it releases the one frictional engagement element, responsive to a rise in the servo hydraulic pressure to the frictional engagement element to be engaged, to maintain an inversely proportional relationship between the servo hydraulic pressure being raised and that being released.

Abstract: A connector for an edge card has a plurality of contact terminals spaced apart in an elongated connector housing. Each terminal has a general U-shape contact portion which extends transverse through a contact cavity slot. The contact portion is horizontally cantilevered from a vertical cantilevered positioning portion which is disposed within a recess associated with the contact cavity, and is further displaceable therein in response to insertion of an edge card into the connector card slot. The insertion of the edge card into the card slot causes the terminal to partially deflect within the recess to bring an opposing contact surface into reliable contact with the edge card.
