Abstract

A method for self configuring automated mechanical transmissions (AMT) and electronic control units (ECU) ensures compatibility therebetween. The method comprehends undertaking a program or subroutine when the vehicle is first powered up which moves the shift operators into a predetermined position. The shift operators include full stroke sensors. Depending upon differences between the commanded shift pattern and the actual shift pattern of the transmission, the specific type of transmission, for example, a twelve speed or a sixteen speed, can be determined.
