ABSTRACT OF THE DISCLOSURE The present invention is a method of controlling the overall operation of an automatic transmission with an electronic controller. The method is used in a vehicle having an engine and a transmission including an input member, a torque converter assembly for transmitting torque between the engine and the input member, an output member, a gear assembly for changing the ratio of torque between the input member and output member. A plurality of friction elements are provided for shifting the gear assembly with a fluid actuating device being movable to engage and disengage at least one friction element. At least one solenoid- actuated valve is movable in response to the presence or absence of electrical power for injecting fluid-flow between the fluid source and the fluid actuation device. A plurality of input sensors provides input signals indicative of predetermined conditions to a controller having memory for processing and storing the input signals and predetermined values and providing output signals to control the actuation of the solenoid-actuated valve.
