Transmission issue?

[K11ng_Ranch]

So here is what I am dealing with. I bought my truck used about 5 months ago, since owning it it has started to almost lag going from 3rd to 4th gear. It's almost like the clutch engages and it takes a couple seconds to shift and then it connects. Sometimes it's even a hard shift. I'm also experiencing sometimes when downshifting from 2nd to 1st and hard shift. Kind of like the clutch is being engaged and then dumped. Sometimes I can hear my tires chirp when this happens. Has this happened to anyone else? And if so what was the problem? I have an appointment scheduled with the stealership to have it looked at and they say it may be covered under warranty. But I just want an idea of what is going on. Thanks guys

Also the truck is a 2011 F250 King ranch 6.7 with a little over 91k miles on it.
