ABSTRACT:
In control apparatus and method for an automatic transmission, an initial hydraulic reference value is calculated which provides a reference value of an initial hydraulic from a shift kind and a throttle opening angle or from the parameter value corresponding to the throttle opening angle and a correction quantity is calculated for the reference value of the initial hydraulic on the basis of squares of a revolution speed of a piston calculated and of the revolution speed of the piston detected, the initial hydraulic reference value being set to the initial hydraulic during the ordinary gear shift and the initial hydraulic reference value being corrected by a correction quantity to set the corrected initial hydraulic reference value to the initial hydraulic when the gear shift to a predetermined target gear shift stage is carried out at a drive point different from during the ordinary gear shift.
