ABSTRACT:
A diagnostic apparatus for a continuously variable transmission the speed ratio and/or the rate of variation in the speed ratio of which are controlled by a shift-regulating device controlled by command signals from a control system. The diagnostic apparatus, which checks if the speed ratio is normally controlled, comprises: a detecting device for detecting an actual speed ratio and/or an actual rate of variation in the speed ratio; a memory storing data for determining normal ranges of the speed ratio and/or normal ranges of the rate of variation in the speed ratio, the normal ranges corresponding to shifting conditions of the transmission which are established by the shift-regulating device according to the command signals; and a judging device for selecting one of the normal ranges of the speed ratio, and/or one of the normal ranges of the rate of variation in the speed ratio, based on the command signals, the judging device checking whether the detected actual speed ratio and/or the detected actual rate of variation in the speed ratio fall within the selected normal ranges.
