The hydraulic circuitry of a factory installed automatic automotive transmission is modified to include a check ball and spring to limit balance oil to a predetermined pressure applied to first end of the clutch regulator valve. When the onboard automobile computer ramps up solenoid oil pressure applied to the clutch regulator valve through a gain valve that acts on a first end of the clutch regulator valve, this pressure is opposed by a spring as well as clutch balance oil pressure that is routed and applied to a second opposite end of the clutch regulator valve.
