While visiting my LHS today I saw a LionChief Plus Mikado running. Great s-l-o-w speed from it's cruise control unit but the sales person said it only controls speed on straight runs but when it climbs a grade or helix, it slows down and then speeds up when it comes back down. (HE claimed constant speed control ascending and descending inclines is only available on TMCC and Legacy engines.) Can anyone with this exact engine verify whether what he told me is actually true or untrue?
Thanks.
