Rear ABS got anything to do with A4LD transmission?

I wonder if this could be a PCM issue as the PCM controls OD and lock up.

No. I already tested the PCM. Transmission shop fixed overdrive and it kicks in like it should.
But even if I installed a valve body correction kit, I don't know what I would do if I found a damaged separator plate.
Because I have not found a place yet that has one available to sell

Something I have wondered about for a long time. Are many of the A4LD parts still being manufactured brand new? I wonder if some of the same parts are being recycled and sold over and over again until parts with excessive wear are being installed in rebuilds. Could this be part of the reason why A4LD rebuilds are problematic?
