RPM jumps????

so i just got my car out of the shop for tranny replacement. anyways when i am driving at a steady 50 or 55mph i noticed the car kind of has a jumpy ideal around those speeds. very little jump i just thought it was weird no lights or nothing car runs awesome just looking for an explanation or answer to why this may happen?

tranny is NOT slipping i shift great and the car runs awesome. its just that little jump in the ideal at those speeds very little most people wouldnt even notice it. i wouldnt even go as far as calling it a jump just a little flucuation on the rpm.
