ABSTRACT:
A motor vehicle shift control apparatus wherein two hydraulically operated frictional coupling devices are simultaneously released and engaged, respectively, to effect a clutch-to-clutch shift of an automatic transmission, including an overshoot control device for compensating the hydraulic pressure of at least one of the coupling devices during the clutch-to-clutch shift such that the amount of engine speed overshoot is held within a predetermined range, and an inhibiting device for inhibiting an operation of the overshoot control device if a preventing device for preventing an excessive rise of the engine speed above an upper limit is expected to be activated, or if the preventing device is in operation. The inhibiting device may be replaced by a device for reducing the output of the engine if the engine speed is higher than a threshold not higher than the upper limit.
