Trannie Slip???

Ok, I am deployed right now, I will do my best to describe the problem as my wife told me.
When the truck is cold, she said it takes a long time for it to shift into second and third(3000RPM). I dont know how accurate that is, but, its all Ive got.
She told me that when the truck is warm, right out the gate, there is no problems.
Would this be a slipping of some kind? Could something as simple as a fluid flush/change fix this? I wont be home for a few weeks still and I dont want my wife to go somewhere to get it fixed unarmed.

mine shifts slow as well when its cold but i don't have any problems with it, you could always have your transmission filters and oil changed if you have a lot of miles on it.

I'm guessing you run an sct with some extreme tunes? If that is the case in the cold that is completely normal...
