Out of the loop in superstock....

So with that logic, and just keeping it related to the transmission: We all have to remove our straight-cut/different than OEM ratio gearsets, take out our roller bearings and go back to bushings, remove our low volume front pump and put a stock one back on, make sure we run the correct number of clutches and steels that the OEM trans had, remove the aluminum drums and put the cast iron OEM ones back in etc etc etc ?

Mine has all of that stuff except the lower ratio first gear. One reason I am slow. LOL

No, because all those parts are replacement for original parts in the trans. A fluid dump valve is not and never has been a part of a transmission. Its new technology. As far as i know, only a th400 has been built right now with the technology. I could be wrong. It also mounts externally so it would be fairly easy to police.

I take that back, th400 and PG. I would love to have one in my stocker. Make the converter loose at the hit so it will 60' and then tighten it up down track to improve ET

People, are working on internal version as we type. AND the dump valve has been around for 70 years. https://en.wikipedia.org/wiki/Hydramatic

Ya know, I doubt that you'll find many Racers that are as hard-core as I am when it comes to interpreting the rule book. And I know that I haven't raced in SS since before most of you were born but I still have my SS number so I'm gonna guess that I can comment on this deal.
I've read the rule book on SS auto transmissions and I don't see why a "fluid dump" would be illegal. If you want to start splitting hairs then in reality a transbrake is a "fluid dump" and for that matter, so is an E-shift. NHRA seems much more concerned as to how you're releasing that transbrake then what you're doing with your pump pressure. Now if you are in some way manipulating your pump pressure to cause some kind of a "delay" in your transbrake release then I would think that you're doing something illegal.
Just my $.02.

Back to the subject at hand...
Only two rules for S/S automatic transmissions.
(Maybe this is three)

1a,
Must be from the same parent company
1b,
Must bolt to to engine block without an adapter.

2, No centrifugal lock up converter ..i.e , the Griner / Coan unit from 40 years ago.

If some tech person told anyone that they couldn't the fluid path internally, then you probably should have never asked.

I agree with all of you. I don't care if the valve is legal or not. I just know that NHRA likes the grey areas to fall on their side of their fence. Hence when they say "if it doesn't say you CAN, then you Can't" . I installed an onboard air compressor system in my stocker(cause i'm horrible at checking tire pressure lol). It doesn't say in the rule book that I CAN have one, nor does it say that I can't have one, but I was told NO in stock, superstock ok but not Stock. GREY area, no specific wording against but also no wording saying its allowed.

Back to the aforementioned......LOGIC........it is comatose.......in Glendora!
