Anyone have any experience with or opinions of the C4 reprogramming kit from Transgo? I have read a few good reviews elsewhere, but would like to hear from you guys. I'm going to replace the tranny fluid bc I know that hasn't been done in a while and my dad said he noticed some slipping when he had it at his place before I moved it down here. I haven't noticed this although it does shift into gear pretty hard. Any opinions/ installation tips? Also, would this be a good time to upgrade to an aluminum transmission pan with a drain plug? Probably 😀
