Which came first? Robot mode or vehicle mode in packaging?

Weird thing that's been bugging me but always forgot to ask and related to this thread:

For anybody in the know, when a TF toy gets assembled in the factory, does it first appear in the robot form then vehicle mode? Like, do the workers then manhandle the item and transform them to the vehicle mode or vice versa?
Same thing like the Yamato Valkyries. Are they first assembled in bot mode then to their awesome jet mode?
