Input speed sensor location?

So I was driving and the vehicle jerked then wouldn't go out of second gear until I parked somewhere and turned it off. Wen I turned it back on a few minutes later it was working fine. So I took it to oriellys to hook up the scanner and it said p0717. Input speed sensor. So im trying to figure out exactly where it's at and all these videos on YouTube and diagrams aren't showing me exactly where it's located at
