kickdown

There is absolutely no room for kickdown linkage on my race car. I would like the trans to shift automatically and consistently. If I tie the kickdown arm on the trans all the way back (full throttle position) I assume that the upshifts will be controlled by the governor and would be consistent. Now the big question: remembering that this is a race car only, no street use, is the transmission going to be damaged by having full throttle pressure at all times?
