On Windows Phone 8.1 there are 2 types of apps, Windows Phone Store Apps 8.1 and Windows Phone Silverlight 8.1.
If you’re using Windows Phone Silverlight 8.1, page transitions equal 8.0 with wptoolkit:
<toolkit:TransitionService.NavigationInTransition>
and
<toolkit:TransitionService.NavigationOutTransition>
But since you’re saying you don’t have Toolkit, it’s probably Windows Phone Store Apps 8.1, so you don’t have the same wptoolkit and you should use Winrt’s Entrancethemetransition class:
<Button>
<Button.Transitions>
<TransitionCollection>
<EntranceThemeTransition/>
</TransitionCollection>
</Button.Transitions>
</Button>
