Thanks,I try to ignore time in the fabric of space-time.I suppose the force of gravity is a fraction: F=, with units of acceleration of .Gravitational red-shifting would be an increase in the time factor, and thus a decrease in the acceleration. However, it would likely be indistinguishable from non red-shifted gravitational acceleration of a lower magnitude.I suppose it would depend a bit on the speed of gravity which is still being argued about.
This article suggests that the speed of gravity may in fact be much greater than the speed of light.http://metaresearch.org/cosmology/speed_of_gravity.asp

If spacetime is only a disortion - a curvature without any physical mediator then it may be conceivable that gravity could be a superluminal phenomenon. Personally, I don't think it will, but it is a tantalizing thought since curvature stores energy in the vacuum.

If superluminal then that implies to me that it propagates backward in time. As the very concept of time is dependent on gravity it seems that gravity could indeed propagate at superluminal speed.
