not sure whats going on!

so i have an 01 powerstroke and the tranny is acting a little goofy. i looked at the fluid and its all nice and clean like it should be but here is my problem. when i go into work in the morning and it was between 30ish to 45ish degrees out that night my truck wont shift into over drive right away i drive it about a mile and come to a longer tight corner and it seems to shift when im in the corner every time. It sits at work for 10 hours and when im on my way home it dose not act like this only when its sitting over night and its "chilly" out. the other thing i have going on is its seems that the rpms get kinda high before it shifts some times but not to noticeable as like when its going to shift into over drive. its not slipping or jerking into gear it just seams like it sits at a certain rpm for 2-3 seconds before it shifts mostly at about 55 to 60 mph. and this dose not happen every time just here and there. Any thought on what my problem could be? could it be a bad valve body.

It could just be that the fluid is cold. When the fluid is cold and more viscous it will have different shifting characteristics than it does once the fluid reaches the appropriate operating temperature.

I know mine is pretty sluggish in the mornings but after about 10-20min of driving its back to normal.

Were you letting your truck warm up longer when it was colder? When was the last time the fluid was changed?

yes always let it warm up. The tranny was replaced 65,000 miles ago so no fluid change yet
