[99coalroller]

I have an early 99 7.3 auto 4x4 and just had a new tranny built for it this past week with a 6.4 converter and a newer valve body as well as a few other little things. My question is this, my original trans would slide into 3rd gear and this one shifts just like my other one. Im pretty sure this is just because of the stock tuning but it really bothers me the way it shifts from 2-3 and i would like it to be firmer and more precise. Has anyone had this problem and can one of yalls chips fix this? thanks
