Take a look at the wear-pattern inside the 3-4 slider. I mean the slider goes far enough, and Fourth is not a high wear gear and all, but after you put the thing back together, center up the 3-4 slider, Pull the input gear forward, and then you will see that the base of the input brake is a good .060 to .100, I'm guessing, further away from the slider than Third is. Every A833 I ever rebuilt is that way.......... which is only a couple of dozen,lol. It doesn't seem to bother it cuz with 3.55s, the 3-4 shift at WOT, doesn't come until after 100mph, so it's pretty rare that you would actually exercise that brass.
