My vote always goes to Reid. I have known Dennis many years, dating back to when he was making his Dedenbear delay boxes in his garage. I worked for ATO transmissions back when his PG case was first being planned . We did a lot of testing of the prototype on our test stand and shop racecars before it was available to public. It is the original and still the best in my opinion. Dennis now offers race cases for the TH400 and 4L80 transmission as well , working closely with Jim Galatioto of ATO for testing and prototype development . Dennis's stuff is like the old Curtiss Mathis TV's, "The quality goes in, before the name goes on". Am I biased? You bet I am! I still get pulled into ATO to do special projects . New Chrysler trans parts should be available after the first of the year from ATO. I really wish any serious racer could have the time to visit with Jim at ATO transmissions. His shop is similar to that found in the F1 world.
