Vehicle seat animation overiding

Hello I am trying to make a custom animation for the vehicle seat but it seems the default sitting animation is overriding it. The priority of the custom animation is set to action.

This is how I would make it look like

But this is what it looks like

The difference between these two animation is that the lower torso still has the default animation.
I tried setting all the playing animation’s priority to the lowest and then playing the animation, but It didn’t seem to work. Thank you for reading
