I have a few questions
How do you know it's not pumping the fluid?
Do you have drive?
If you don't have drive then I would suspect that it is sucking air and you haven't fitted the seals between your transmission and valve body correctly

It's on jack stands, I pumped 3.5 quarts into it until a slow drop comes out fill hole, then started car and let it warm up, removed fill plug and it's a steady slow stream of fluid coming out and transmission malfunction warning pops up, I also changed the mechatronics sleeve tonight

Okay did you make sure the bottom of the transmission pan is flat? Or slightly higher at the rear?
If yes, then I think your seals between the valve body and transmission are not sealing correctly
Did you replace them?

Did you confirm that all the bridge seals were correctly installed? Did the mechatronics torque down fully? Are any of the pins on the connectors pushed in? Was the sealing ring on the new pan's fluid uptake tube correctly installed? Some pans have a seal on the uptake tube on the pan when new, was it removed?
What are the malfunction codes you get? What do they mean?
Hate to say it, but I'd be ready to strip it back down and figure it out before I ran it again. If there is no fluid circulation, there's no lubrication.

Yes I replaced all 4 valve seals and the bridge seal the new valve seals stuck out maybe 1/8 inch but what I've read that is normal, bridge seal can only be installed one way so Im pretty sure it's correct

It sounds like it's not pumping fluid through the system at all. Either the pump isn't running, or the system is stopped up somewhere.

Bapmic pan
Still brain storming on what could possibly be wrong. Has anyone used the Bapmic pan/filter for 6hp26? That's the one I used but starting to question if it's uptake neck is sealing correctly when I put the pan on. My transmission is GA6HP26Z

You told us you took the plastic cap of the filter/pan assembly, do you rember seeing a green (at least with ZF assembly) "O" ring seated on the filter pickup assembly, under plastic cap and did you put some ATF fluid on the ring, to prevent it from hanging on the transmission, while you were assembling it. Absent the Oring it will suck air all day long...
Good Luck!

I don't have an OEM pan on my car and it's fine.
But it's a very good point that the oil ring may be damaged and sucking air.
If you have a replacement oil ring it would be good to replace it and test
I really thing this issue is something small
I am happy to read that you are trying to fix it
Keep listening to people's suggestions and keep trying
Great people on this site to help when ever they can
