Going to have to get a legal transmission case. FI is out of stock. Jegs has cpl two piece as does summit. Trying to see if both have a BBM bell I can change out, Beats xxxx out of mid plate as adapter. Loosing 14lbs when swapping out this JW does not hurt anything,
Any real difference in ATI which summit has and Reid which jegs has?
-
The one difference I do know of is Reid has an adjustment for the brake release. You can take some of the initial hit out of it.
-
In our jrfuel car we use a Reed case because we race heads up .05 pro tree NHRA Heritage and NHRA Comp Elim .06 full tree , so we can adjust [ slow down] the release of the brake.
We just have to get it creditied, every 3 or 5 years.
-
They are all pretty much thesame minus the dump restrictor that Reid has.
-
dump restrictor? Is that what the bolt on rear of JW is.It is to upper left of case. Not issue if running box but can see where could help if no box. But heck old guys rarely need to slow down reaction times. LMAO
-
Yes JW has one as well
-
Same question on DRR and lot f comments about ATI haveing issue with park setup and disengaging at time. Looking like Reid from comment I have gotten so far. Problem is in finding one available.

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.
