I am have some trouble figuring out what this “solenoid” is on this auto transmission

The transmissions I have been finding are auto JDM, on ebay and jdmenginescorp.com

I need a replacement transmission and these are all I can find, and would like to keep it an automatic.

The issue is with the “solenoid” the US auto transmission out of a CRX has “ one solenoid” and it’s a lock up control solenoid

The JDM auto transmission has “ 2 solenoids” I need to find out what the other solenoid is and does

Or if I can just buy the transmission and install it, which just hooking up one of the solenoids, and if there would be any issues.

Here are some of them JDM auto transmission with 2 solenoids





heres is a US auto transmission with 1 solenoid



thanks!!!
