Abstract:
A reshift control apparatus for an automatic transmission comprising a plurality of friction elements arranged to be selectively engaged and disengaged to select one of gear ratios, and to perform a shift to another gear ratio by changeover of friction elements to be engaged, the reshift control apparatus comprising a shift controller so configured:that the shift controller permits a reshift when another shift request is produced at a time during said shift; that, in the case of a reshift in which an engagement side friction element in process of engagement in said shift is to be engaged continuously in said reshift, the shift controller makes an operating oil pressure for said engagement side friction element after a reshift command, equal to a value of an oil pressure to be given in a manner of time series if the reshift were a jump shift to a gear ratio reached by said reshift, initiated at the time of a command for said shift; and that the shift controller makes an operating oil pressure, after the reshift command, for a disengagement side friction element to be disengaged in said reshift, equal to a value of an oil pressure to be given in a manner of time series if the jump shift to the gear ratio reached by said reshift were initiated at the time of the command for said shift.
