E shift solenoid code P0770

My car is having hard up shifts between gear two and three
I have drained out the transmission fluid and am dropping the pan and need to know what solenoid to take out and where it is and then test

When I look at the diagram where exactly is the e shift solenoid? I see the red arrow pointing to the solenoid in the diagram you sent could you direct me in the video I sent using the color of the connection points that I will have to unplug And I will send video of bottom of trans valve body can you direct me to the solenoid I need to take out? Is it in the front left of the video where there are 3 solenoids close together? And I sent this video to a transmission mechanic and he said there may be a roller bearing/ bearing roller missing do u see this and where n what is that? Agian ammco gave me a p0770 code and the trans is having slightly hard upshifts between 1-2 gear and 2-3

Ok I tested the sylenoids and they all worked and put em back however when I went to put in the drain plug I had left the wires hanging I no I put em back up in the clip however they must of come off and can see them sitting rt above the drain plug on the inside of the pan. Should I break the seal to the gasket and take the pan off and hang them up correctly or would I be able to just put the drain plug in and fill it back up with fluid? I’m waiting on a new drain plug from eBay that’s why I haven’t filled it back up yet and realized this after testing sylenoids and putting gasket w gasket maker n pan back up, stupid mistake ino...

Please let me know if it’s OK that I did not hang the wire harness to the solenoids when I put the pan back on. Can I fill up with transmission fluid or do I need to take the pan off again and hang it back up on the clip?
