yes you remove the one bolt on the side of the trans there, and slide the whole assembly out.
i'm guessing the cable didn't come out because it's still atatched to the speedo gear inside, which you can remove by removing the speedo gear retaining clip.
as for jrichker's comment about you possibly causing a problem by removing that clip........you'll have to get it out and look at it to see whats what......and if you can get the clip back in......i'm guessing you are supposed to remove the entire vss assembly, then remove the speedo gear, then the cable comes out.......with the clip still installed.......not positive on that though
