new engine and wont go over 60mph

i picked up my jeep from the shop 2 days ago, i was being carefull not to push between gear as its new engine.
yesterday on the HWY i noticed that it will not go overr 60mph in 5th gear !!
i could "push" in in 4th up to 65 but that was it, (the rpm match the speed)
at take of it was very slow (strugling)
idrove 50 miles and went to the smog test and pass.
this morning at take off it's a lot better, 4th gear will go to 70 / 75mph and when i change to 5th gear it will go down to 60/65 mph @ abput 2800 rpm and wont go any faster.

tomorrow i'm bringing it back to the shop, what could be causing this?
