I have a 1990 300ZX TT with an AUTO. I was recommended to a HALTECH, but it looks like those are for manual transmissions only. Is NISTUNE my only option? I live in the Detroit, MI area. Chin seems to be MIA and I was referred to Dennis out here, but he is only familiar with Haltech. I was hoping for someone local-ish but of course extremely reliable and skilled.
