ABSTRACT:
In a system for shift control in an automatic transmission, wherein a hydraulic control device is operated to selectively switch the engagements of frictionally engaging devices and any one of plurality of gear stages can be achieved in accordance with a preset shift map, a system is provided to judge whether shifting is abnormal or not. When it is judged that the shifting is abnormal, oil pressure for engaging the frictionally engaging devices is raised. With this arrangement, the durability of the frictionally engaging devices can be secured.
