08 tundra transmission problems

I parked my truck at a store and when I came back out it wouldn't move. The shifter moves freely and appears to recognize that it's shifting between gears but will not move under its own power. It's never had any transmission problems, slipping or slamming into gear. So I took it home and plugged it in and got code p2714, pressure control solenoid D stuck open. From what I found it's part number 35290-34010, so I ordered the oem Toyota part. Anyone have experience with this? Any tips or pointers for replacement? Do you think this will be the culprit? Any information would be greatly appreciated

 

Also I noticed when I revved it up in reverse it moved slightly of that means anything..only did that once to be safe
