It depends on how rigorous you want to be. Firstly, I suggest posting this to the Relativity forum, where you have a better chance of attracting people who know the answer and are interested enough to answer. I will tell you what I have read/heard.kurious said:

There is a manifestation/form of gravitational interaction called "gravitomagnetism." I have seen no reason to doubt its existence. It follows naturally from a first order approximation of Einstein's equation. That is, the zeroth order approximation gives you Poisson's equation for Newtonian gravity (basically the F ~ r

Strictly speaking, this is not exactly like the magnetic field, even in analogy. In fact, it is only like this in PN1. Any higher (PN2, PN3, etc.) and you lose the analogy, so I've heard/read.
