Should I do any thing to my transmission?

[CHEVY & GMC FOREVER]

I am rebuilding my motor well not me exactly I get drunk to much so I'll have some one else do it cause the last time I rebuilt a small block had to be about 1991 and I was drunk of my ass, so anyway the carb was "close" (in my words) the timing was messed up so again "close", I'll never rebuild a small block unless I'm in an beerless area and that's no where I want to be but it was fun, so I want everything to be accurate this time. So what I was wondering is should I do anything to the trans??? a shift kit something along those lines???
