I have a 2007 LBZ with the basic mods and dsp5. Makes 550hp 1000ftlbs give or take. Trans is stock with transgo and needs some help. It is not smoked but has limped a few times. Converter or clutches will sometimes chatter if you roll into it on the highway. So what do I really for a build parts wise. I have the tools to do this trans. Did trans work for dodge for 25yrs. So I'm sure I can take it apart and put it together. What is the best bang for buck to do this? I have been looking at the kit that Limitless has and its not cheap. Would a PPI stage 4 be an equivalent option?
