A work vehicle has two transaxles carried by a chassis each having wheel end units rotatable to drive ground-engaging members about wheel axes and having electric machines powering transmission configured to effect multiple gear ratios. The electric transaxles are operationally mechanically uncoupled. One or more sensors detect speed, heading, and loading characteristics of the work vehicle. A controller, having memory and processing architecture, is configured to process control to: receive from the one or more sensors input of the speed, heading, and loading characteristics of the work vehicle. The controller determines a shift pair sequence for shifting the first transmission and the second transmission based on the received input of the speed, heading, and loading characteristics of the work vehicle. The shift pair sequence defines a shift time (tS1) for shifting the first transmission and a shift time (tS2) for shifting the second transmission in which the shift time tS1 is the same or different than the shift time tS2. The controller generates a first shift command to shift the first transmission at the shift time tS1 while the second electric transaxle drives the work vehicle and generate a second shift command to shift the second transmission at the shift time tS2 while the first electric transaxle drives the work vehicle.
