In the anime, episode 54, Trunks ask his father to transform into a SS3, Vegeta just laughs at the request.

I couldn't find anything on the manga, and the scene above never happened in the pages.

Instead there's a scene with Vegeta training Trunks, chapter 17, in the Gravity Room, both in their base form, without any dialogue.
