Guy's, give this a try and see it it helps. First, you cannot repeat CANNOT push the shift lever on a diagonal from first to second as this makes an "N" pattern and not an "H" pattern. Now a tip to help make the "H" pattern without consciously thinking about it. Grip the lever with your palm facing UP and curl you fingers back towards your face to make the shift. You will find this stops (or sharply decreases) the tendency to move the lever on a diagonal and encourages an "H" pattern movement.
