Hoping? do you mean hopping? maybe it is the tires.
Yes Hopping.... I have replaced tires, it seems like rear end Hop, but can't figure out why?

I had the same problem on my 08 FJ and they fixed it - torque convertor is bad - Toyota will only replace transmission. You buy the parts and have a local trans shop install
