so I have a p0807 code which I know is my cpp sensor , anyways sometimes when I'm shifting its as if my rpms get stuck for a moment and don't drop down like normal and sometimes slightly go up in the midst of shifting , I tried to attach a video but I can't ... anyways it's annoying me . Would like to know if it's doing this because of the sensor , the fix and how much it will cost
