Well it is not a good game to play if it is an automatic. And i think LaCrosse came whith automatic only. The thing is that your engine has a connetcion trough your drive line to the road and the engine gets a drive back even if is in neutral. On Manual transmission you can disconnect the drive between engine and transmission by puting it in neutral so thisway your engine can idle.
