Abstract
A method of controlling a transmission of a vehicle selectively either in a first mode of operation in such a manner that the transmission is shifted among a plurality of speed stages according to a first shift pattern, or in a second mode of operation in such a manner that the transmission is shifted among those speed stages which lacks at least one intermediate speed stage in the above-mentioned plurality of speed stages according to a second shift pattern, according selection between the above two modes of operation. On-off controlling of a lockup clutch is also changed in two modes according to the selection between the two modes of speed stage shifting, when it is incorporated in the transmission.
