'09 Eos was throwing P0747 code (pressure control solenoid sticking) even after replacing fluid with Ravenol and changing filter. Bought a replacement unit on Ebay from a seller who says this unit was from a working transmission that had a bad snap ring. I hate going with used, but the AJ02E027770AJ is impossible to find new and I don't trust the Chinese rebuilds. I know the AJ units are iffy, but it's what's available.

I'm wondering what will give me the best chance of success. Is there a way to clean the solenoids and valve bodies to give them the best chance of working?

Should I put my control unit on the used unit?

Thanks in advance.
