Building a unit for a guy, it’s a pieced together truck with engine and trans swap. Then I have a couple cores for parts, pulled the pump out of one that almost matches. Both have the press in case seal. Neither have the shaft sensor. Stator shafts measure the same. Only different I see is a square cutout on one pump where the boost valve is. The unit I’m fixing exploded the pump rotor and messed up the housing. I’m a little embarrassed that as long as I’ve been building these things, I never took the time to learn interchangeably. Smh
Should cover all your pump interchange questions
It's tough to say with just pictures you've added of the back
thanks. Unfortunately that doesn’t help tho. I actually have those atsg manuals and that is for much older. These transmissions are much newer, like 2002 and newer. I think I had mentioned they both have the press in CASE seal around the pump body. No oring groove machined in either one. The only difference I can tell is the area where the boost valve is. One has a notch in the pump body and the other doesn’t.
I misread, going through posts too quickly this morning!
If they both have the same stator height/hole location they should be fine
In your first photo, it looks like it has the shaft sensor hole but plugged with the dummy plug
Make sure you measure the location of the holes in the stator. That's the key. The height overall will be the same, but the oil hole locations change

will do. If they differ, can I swap the stators? Thx! As always!
A Pre-ISS/ Non-ISS Pump (Stator-Support is the crucial component) must have a Corresponding Input-Shaft as the Location of the Solid Teflon Sealing-Rings differ.
In your particular situation (if I am seeing the Components that I believe are Correct)...
The Pumps with an Iss Dummy-Plug (Stator-Support) should have an Input-Shaft with the Solid Teflon Sealing-Rings slightly relocated.
Swapping the Pump (Stator-Support) will require the Input-Shaft that Matches also be swapped.

makes sense. I think the damaged trans has reluctor notches on the input shaft. I don’t think the other one does. I’ll double check when I get home. If that’s the case, I should be able to press out the original stator shaft and press it into the replacement pump (the one with the square notch) and use the same input shaft and drum. The reason I’d like to reuse the original input drum is because it has a sonnax reinforcement kit on it.
A Note on the Input-Shafts:
Much Confusion has come from Input-Shafts that have NO Reluctor-Teeth...
Yet are Produced with the Solid Teflon Sealing-Rings moved.
(Pump with the ISS Dummy-Plug in the Stator-Support Shaft).
So just be ever so careful of mixing and matching these Components from the nigh-ISS Model-Year Cores.
