Abstract of the Disclosure, A transmission diagnostic control effective when there is an apparent loss of the transmission output speed signal for determining if failure is real and if so, the cause of the failure. When an apparent loss of the output signal is observed, the transmission is successively upshifted through its various forward speed ratios while the transmission input speed is monitored to detect the occurrence of an upshift-related reduction thereof. If the shifting fails to produce a reduction in the transmission input speed by the time the transmission has been shifted to the highest available speed ratio, a total transmission failure is indicated. If the shifting produces a …
