I cant say about the ATS but seeing all the Allison's Merchant builds using his own converter, I would say its a good one. Pm him "dmaxallitech" I am sure he can give you the details.
Well the truck belongs to a friend of mine and he is not easy on the throttle. The trans is sitting on the garage floor right now. So were just trying to make sure we do everything we can to make it bullet proof.
No, you're blowing through the clutches first. As soon as you replace those with better ones and a CoPilot, you'll start blowing through the converter. Everything is kinda designed on an equal plane with the Allison (parts are well matched in terms of HP holding ability).
PPE Hot 2 requires pretty much the whole shootin' match.
