The residual of the steady state solver is the residual of the steady state solution, while the residual of the transient solver is the residual of the transient solution. These are different solutions qith different physics involved.
Try to put a time step of 1e-16. Even the most complex problem with a poor mesh converges because essentially nothing happens between the iterations.
In single-phase flows with RANS yo should get a converged solution with the Coupled solver in less than 500 time steps. If not, you should improve your mesh before simulating the transient problem.
