A launch control system for a vehicle having a powertrain includes a transmission configured to selectively perform a transbrake operation to temporarily lock the transmission to hold the vehicle stationary while an engine throttle position is increased for a vehicle launch, an actuator configured to initiate a transbrake creep operation, and a controller in signal communication with the transmission and the actuator. The controller is configured to (i) command the transmission to perform the transbrake operation, (ii) receive a signal from the actuator indicating a request to initiate the transbrake creep operation, and (iii) command the transmission to momentarily disengage the transbrake for a predetermined period of time to enable the vehicle to perform the transbrake creep operation and move the vehicle forward while maintaining the increased engine throttle position.
