I have an 07 obs 1500, had gm do a recall for 1/2 shift slipping. A new accumulator valve was put in making the 1/2 shift very firm and very harsh wot. The other two shifts were not affected but are sloppy. In debating buying the hp tuners and tuning the truck and trans. Or maybe just a shift kit to leave it alone. This is just my daily driver/ plow truck not looking to race people or bark 2nd gear. I just want all the shifts to be the same. Anyone have any recommendations on shift kit or should I just go with the hp tunners and adjust it there?
