i bought a used tranny for my car and it came with a atts unit. No computer, just the gear box. I already got one extra. Don't need two. I only saw one of these for sale on here and it was like 1000 bucks. I'm looking to get 150 out of it. Don't know how well it works, never used it. Shipping should be about 30-40 bucks. If you want to come get it in chattanooga, thats cool too.
