A transmission control system is provided for a work machine that has a transmission and a traction device with a brake mechanism. The transmission control system has a speed sensor configured to generate a signal indicative of a travel speed of the work machine. The transmission control system also has a controller in communication with the speed sensor and the brake mechanism. The controller is configured to determine when a transmission gear change is desired. The controller is further configured to adjust operation of the brake mechanism in response to the signal from the speed sensor when the transmission gear change is desired.
