Higher shift point when cold

Just bought an 04 F350 Diesel .... and noticed that when it is cold (below freezing) the trans seems to shift at a much higher rpm. As soon as it warms up, the shift points return to normal.

Is this normal?

I have a 2003 and it does that too. I understand that the trans program get's modified with "flashing" so maybe the shift points vary by flash level?
