I am not aware of any way you can change the transition animation publicly.

If the "back" button is not necessary you should use modal view controllers to have the "push from bottom" / "flip" / "fade" / (≥3.2)"page curl" transitions.

On the private side, the method -pushViewController:animated: calls the undocumented method -pushViewController:transition:forceImmediate:, so e.g. if you want a flip-from-left-to-right transition, you can use

[navCtrler pushViewController:ctrler transition:10 forceImmediate:NO];

You can't change the "pop" transition this way, however.
