2003 1500 5.7 bucking when reaches 55 mph

Truck seems to buck but not hard when it reaches 55mph to 60 seems like when it shifts into overdrive. If I take overdrive off it doesn't do it? Any ideas?

Moving to the correct section. Please state mileage, repair/maintenance history, any aftermarket modifications, etc.

my 01 was doing that, especially on the on-ramp to a hwy when accelerating. I cleaned the fuel system and changed plugs and it fixed it. Probably tuneup time.
