ABSTRACT:
A control valve for controlling the engagement of a friction drive clutch for an automatic transmission having multiple clutches and brakes for establishing a drive mode following a neutral mode wherein the valve regulates pressure distributed to the drive clutch and wherein the valve is in fluid communication with a second clutch whereby the latter acts as an accumulator for altering the rate of pressure buildup in the drive clutch thus eliminating harshness in the clutch engagement.
