Abstract
A method of monitoring an output and adjusting the action affecting the output continuously for an electronic automatic transmission system wherein a controller is programmed to 'learn' from the results of its operation. The method includes monitoring the speed of an input member and the instantaneous fluid volume of a friction element. The method also includes setting a learned volume value equal to an instantaneous fluid volume whenever the input speed is within a predetermined range of a predetermined speed. The method further includes comparing the learned volume value to a stored fill volume value at the end of the shift and adjusting the stored fill volume value based on the difference between the learned volume value and the stored fill volume value.
