Changing a value of transform variable

i have a transform variable that have a default value but I want to change the value, shift the transform a little bit on the Z axis but there seem no apparent way to do it like transform + transform.

Hi, I hope, I got you correctly, but this is, what might help: break the components and add some value to the Z component.

No need to break location vector:
