Exclamation Hesitation/bucking at highway speed

I have a 2006 F-250 with 77,000 miles. Whenever I get above 50 mph and give it light to medium throttle my truck hesitates and bucks, but then takes off without a problem. There is no problem at all when I burry the pedal.
I took it to a local diesel shop that has done work on truck before and is very reputable. They first said it sounded like a sticking vein in the turbo. So they rebuilt it but it was still happening.
They then said it was a torque converter so I had them replace that. When I first go the truck back it seemed to be fine but then after about 300 miles the hesitation/buck came back and it seemed to be worse.

Any suggestions????

Check your tps is working properly. The tranny compares the signals from tps [throttle position sensor] & the VSS [vechile speed sensor] to determine which gear it is supposed to be in. You may be unable to stay in high gear.
