I would think the shock from the tires chattering on a launch with instant clutch engagement and the load on the gears when that much torque is being applied to the drivetrain is what causes the stress on the transmission pieces. Whereas an automatic transmission has a smoother transmission of shock with the torque converter. Its difficult to build a manual transmission to withstand the rigors of drag racing, and guessing its why not many drag race their panteras given the expense of replacing parts. HP after all is just a derivative of torque. Hence why most transmissions are rated with torque values. Maybe starting a burnout where you are trying to break the tires loose to do a burnout you would have abnormal stress, but after the wheels are spinning and there is no traction, there is a slight but constant load on the transaxle, probably less than a load placed at cruising speed on the highway. The difference is less air is flowing past the casing than if you were at speed and moving faster, so less ambient cooling and because the gears are spinning faster and creating heat that can be detrimental. That is how I perceive it but would be interested to hear discussion.
