Posted by JohnE Dave (Goerend) told me he and ATS bought the semi-circle tabbed machined cover and clutch plates from the same supplier
This upset me and I called Clint Cannon, owner of ATS and asked him if this was true. Here is what Clint said.
When ATS was working on their prototype for the Triple-Lok T. C. cover they had a machine shop in Tennesee make up some preliminary designs, to ATS's own blueprints. These first few prototypes were never sold to the public; rather they were intended to be used to test and re-test the concept of the Triple-Lok on Clint's own trucks. (Clint has a Ford Powerstroke as well as a Dodge Cummins, and most of his employees have Dodge/Cummins)
The agreement with the machine shop owner was that the preliminary design of the T. C. Cover and tabbed clutches was owned by ATS and the machine shop guy was NOT to sell, distribute or circulate the design in any way.
The machine shop owner did not keep his word, and sold that early design to any trans shop which anted up the cash. This included Dave Goerend.
ATS learned from this and bought their own new 4-axis CNC machine, (probably cost in excess of 200 grand!) and began to machine their own prototypes. They DID NOT rush this design. They re-tooled and re-tested it many times, in order to get it perfect. They tested EVERY component in the 47RH (and later RE). The present Stage IV design is the result of YEARS of testing on their own trucks. Clint estimates he blew out 25 transmissions over the years, testing EVERY component of the ATS Stage IV. Don Ramer estimates he blew out 20 transmissions testing components. All this before they sold a single Triple-Lok!
These guys are thorough, dilligent, dedicated, smart and tough! They have re-engineered, cyroed, heat-treated or re-designed EVERY marginal component in the 47RH & 47RE.
That's why I got one. I'd do it again in a heatbeat.
