Hydraulic control system for automatic transmission such as a continuously variable transmission

In an automotive vehicle having driven wheels:

• an engine;
• a transmission having an input member drivingly connected with the engine and an output member drivingly connected with the driven wheels, the transmission including frictional element means for interrupting a power delivery path between the engine and the driven wheels;
• a source of pressurized fluid;
• a manual valve communicating with said source of pressurized fluid and the frictional element means, said manual valve being shiftable to a forward drive position wherein said manual valve establishes a fluid feed line through which the pressurized fluid is supplied to the frictional element means from said source of pressurized fluid, a neutral position wherein said manual valve establishes a drain fluid line through which the pressurized fluid is discharged from the frictional element means, and a reverse drive position;
• means for delaying a shift to neutral in the transmission when said manual valve is moved to the neutral position from the forward drive position;
• and
• fuel cut control means for interrupting the supply of fuel to said engine as long as the engine speed is higher than a first predetermined value after a predetermined operating state of the automotive vehicle has been established and until the enginge speed drops to a second predetermined value that is lower than said first predetermined value, and allowing the resumption of the supply of fuel to said engine when said manual valve is shifted to the neutral position.
