The dog is a fairly robust part, have you actually worn one (of the AM stainless dogs) out?
Yup. We managed to break one in half with our auto shifting code several years ago. We had made our own transmission with two CIMs + another motor that was based off of the AM shifting transmission. The problem was that when our driver would hit the walls in the room we were testing, it would shift into the slower gear violently. Now that I think back to it, the problem probably occurred because we were testing with a large diameter cylinder because our little ones didn't arrive yet, so we increased the pressure to 120 psi to get a faster response when we shifted.
