Transmission builder in Wisconsin
well after 184,000 glorious miles my old 4l60e is on its last leg (surprising right). I'm glad she lasted as long as she did especially since i drive like a pissed off teenager. Anyways in the past i used maddog performance transmissions out of Georgia which there customer service is great and they stand behind their work but i was wondering if anyone had heard of Automatic Transmission Design in Germantown, WI?

the local tuning shop says they are top notch, im not sure how much i trust them though because they told me if they dyno tuned my truck id only get 5-8 more hp out of a tune given my existing mods. I'm pretty sure i gained more than that with my nelson tune. I am aware that i could get a FLT trans or a Performabuilt trans for just under 2 grand but if they can rebuild mine for cheaper and have it be just as strong im willing to give it a shot. My future plans for this truck is just a TSP 224r cam 3k stall and maybe a 100 shot of laughing gas. With all of that said what do you gentlemen think?
