2015 nissan sentra 1.8l cvt issues
 

I have a 2015 nissan sentra sv 1.8L. When I started my vehicle I noticed it wouldn't go over 10mph. So I hooked up the reader and got a DTC # p0965 solenoid B. So I removed the transmission pan and pulled the valve body. I cleaned it up but didn't reinstall it bc I don't wanna waste time. I would like to narrow down the issue. I'm not sure which solenoid it is, but the reader says solenoid b. Not sure if it's easier to replace the solenoid, which if I do I'm gonna replace all of them. Or if it would be easier to just replace the entire valve body. Which if I do, I'm having trouble narrowing down which model I need. Any help would be great. Here are some pics to help the nissan pros narrow it down. TIA
