Slick shifted a833 on the street?

Slick-shifted one of Mine, left all of the teeth & syncro-sleeve splines on 1st gear, took every-other off the rest. Drove it around no problems, You just have to be willing to
learn how to shift & double-clutch, after You do it's easy-peasy. I could still downshift into 1st moving, but You really have to be "on it" to do so cleanly. With 4.89's, I didn't
have the need to suddenly, LOL!
