Abstract
A transmission of a vehicle has a first gear and a second gear that corresponds to a lower gear ratio than the first gear. A transmission management system for the transmission comprises an enabling module, a shift control module, and a disabling module. The enabling module enables a second gear start mode of the transmission when a vehicle speed is less than a predetermined speed. The shift control module commands operation of the transmission in the second gear when the second gear start mode is enabled. The disabling module selectively disables the second gear start mode when a user commands a gear shift to the first gear while the second gear start mode is enabled and prevents the enabling module from re-enabling the second gear start mode after the second gear start mode is disabled.
