An improved adaptive line pressure control which detects the occurrence of run-through and overrides the normal adaptive pressure control in response to a detected run-through condition so that the line pressure during subsequent shifting is increased instead of decreased. A run-through condition is detected by measuring and comparing first and second time indications corresponding, respectively, to the interval of ratio change during the shift (shift time), and the interval between the generation of a shift command and the actual initiation of ratio change (delay time).
