Swift 5 implementation of Arne's answer:

extension UINavigationController {
  func pushViewControllerLegacyTransition(_ viewController: UIViewController) {
    let transition = CATransition()
    transition.duration = 0.25
    transition.timingFunction = CAMediaTimingFunction(name: .easeInEaseOut)
    transition.type = .push
    transition.subtype = .fromRight
    view.layer.add(transition, forKey: nil)
    pushViewController(viewController, animated: false)
  }

  func popViewControllerLegacyTransition() {
    let transition = CATransition()
    transition.duration = 0.25
    transition.timingFunction = CAMediaTimingFunction(name: .easeInEaseOut)
    transition.type = .push
    transition.subtype = .fromLeft
    view.layer.add(transition, forKey: nil)
    popViewController(animated: false)
  }
}
