Abstract
An improved control method and control system for an automatic change gear transmission (10) driven by a throttle controlled engine (12) is provided. The control system includes a processing unit (30) for receiving inputs indicating at least throttle position (18) and engine speed (20) and for processing these inputs in accordance with a program to determine the correct engaged gear ratio and for issuing command signals to a transmission shifting mechanism (26). The processing unit includes logic rules to determine conditions of operator selected stable operating conditions and to lower the engine speeds at which upshifts are commanded in response to such determination.
