transmission question

If it chirps the tires that easy with a regulation shift kit, I have to wonder if some valve body mods were done also? I've only seen a manual VB shift that hard under light throttle. As 67 said, a lighter setting on the linkage may help.........The last time I was in a stockish 727 that started shifting that hard, it died within a month, lol. Not trying to be doom and gloomish, just what happened to me.
