This pic shows the four teeth of second gear that got striped when I shocked the tranny by up shifting hard and not pressing in the clutch all the way. It also didn’t help that my engine was superheated by the Rotrex system superheating the engine via overheated air and Convection! My tranny was much hotter than it was intended to be due to the poorly designed GBP Rotrex system. Second gear doesn’t break so easily under normal operating temps and only <400whp..
