An improved control system and method for an automatic mechanical transmission system (10) having an operator selectable (44A) cruise control mode of operation is provided. In the cruise control mode of operation, if fueling to the engine is at approximately 100% of full throttle, the cruise control speed error (SE) exceeds a speed error reference (REF-SE) and a time derivative of output shaft speed (dOS/dt) is less than a first reference value (REF-1), which reference value has a negative value, then shift decisions will be based on enhanced performance shift profile (E-F-G, U-V-W) similar to "kick-down" shift profiles.
