A gear shift operation device for a vehicle to which a multiple-stage automatic transmission is mounted, is provided. By a control lever being manually operated in a range switchable mode, a range position is switched at least between a D-range where automatic transmission is performed and an R-range, and by the control lever being manually operated in a manual transmission mode, a gear change is performed. An operation reaction force when the control lever is manually operated is set larger when the gear change is performed in the manual transmission mode than when the range position is switched in the range switchable mode.
