One can only make some guesses based on your two line description of the problem. First how does your transmission fluid look? Transmission services lately?
Check the ATF level, and colour.
If it's low, it'll be reluctant to up-shift, same applies if it's dirty.
ATF does require replacing.
If it's almost black, I'd say the clutch bands are burnt.
If it's grey, (metal swarf) then suspect more serious mechanical failure
