I'm at about 600 rwhp. If I hammer it when I'm in auto shift mode and let the trans drop a gear or two it downshifts hard. It's a violent downshift at WOT, much more than it was when the car was stock. Can the transmission handle this for long? Is the only way to save the trans is by manually downshifting then putting it into auto shift mode? It just feels hard on parts when I go WOT in Drive.
