Gravity is more of a 'state' of local space, rather than
anything that can be transmitted (basically, a measure
of how bent space-time is by mass).

You do have postulated 'gravitons' though, which are
theoretical particles which are exchanged in gravitational
interactions. They're thought to travel at lightspeed.

Also,'gravity waves' are another postulated feature,
these being created by fast moving (relativistic)
massive bodies. These probably travel at lightspeed
as well.

(I've just grabbed those two from a dictionary of physics,
so I can't give any more info!).
