In a vehicle having an engine with a throttle means to regulate the flow of combustible elements into the engine and a throttle position indicator with a variable electrical output in communication with the throttle means such that movement of the throttle means translates to a change in the variable electrical output of the indicator, a transmission system including an input member, 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 input sensors for providing a signal of the speed of the engine, output member, input member, and a controller for processing the signals and providing output signals, a method of determining the angular position of a throttle on an engine for use in controlling a vehicle transmission, said method comprising the steps of: sensing an actual throttle position as a function of the electrical output of the indicator; determining whether the actual throttle position value is at least equal to a first predetermined position value stored in memory; incrementing a throttle position error counter if the actual throttle position value is not less than the first predetermined position value; determining whether the actual throttle position value is less than a predetermined closed minimum throttle position value stored in memory if the actual throttle position value is at least equal to the first predetermined position value; determining whether the count value on the throttle position error counter is greater than a first predetermined error value; and defining a predetermined default value if the count value on the throttle position error counter is greater than the first predetermined error value.
