Automatic Shifting Problems

I just purchaced my first KIA, FORTE. Great car so far except for a minor, intermitted shifting problem. Whe car is up to normal temp, driving for at least a half hour, the 2-3 & 3-4 upshift hits hard, slight engine RPM surge. This has happened about 10 times.
It has been doing it since new. Now has 1500 miles on it. Dealer says they will check it out on our first service.
Has any one else having this problem?:(

I have had the same problem with mine. High rpm between shifts and slams into gear. But mine also shifts very quickly. If I slow down to make a turn and thentry to get up to speed again, it will up shift to drive within a few seconds, mostly before I hit 60Kmph, leaving me at about 1200 rpm on the tach and no power, and you really have to put your foot into it to get it to kick back down to the point of when it does, it's almost a redline on the tach. Service keeps telling me to wait for a ECU update. Been telling me that for two months now.
I figured that is just how the car was programed, mine has been like that since mile 12 when I got it. I have a more serious issue where it keeps revs to long (at least I feel) and then slams into the next gear. If I have to drive with a bit of speed, like to get up to speed on short on ramps, I use manual mode so it shifts when I tell it.
