Don't disconnect the lines running to it, unless its a last resort. If you take the lines off, you have to rebleed the system which isn't fun or cheap ( you HAVE to use Honda PS fluid, which is pricey).
The vss has a gear which meshes with the transmission, so it can be kinda "wedged" in there by the friction between the gear teeth. Don't be afraid to give it a good pull.
I'm sure you've already seen this, but just in case you missed it:
