A method for transmission upshift sequencing includes detecting a lift foot gear hold condition is met and that a current engine speed is greater than a pattern gear engine speed for the current gear. If these conditions exists then the current gear is held until a first sequence timer expires and then an upshift event occurs to a first gear having an engine speed less than the current engine speed. The first gear is then held until a at least one other sequence timer expires and, thereafter, at least one other gear is selected and held until the engine speed is less than or equal to a pattern gear engine speed.
