Iirc you will need to remove the side cover because there is a black thin metal clip on the inside of the trans that holds that in place. im not 100% on that but the last time i messed with the trans those solenoides are held in with a thin metal (about the thickness of a paper clip)clip on the inside that you have to pop out before that comes through the trans. and if im not mistaken that is removed through the insde. goodluck man.
Actually, its a bit easier then ya think. but i understand. it is a PITA either way. Lol either way good luck!
