transmission fail safe mode driving uphill

During driving uphill and applying gas pedal, transmission went in fail safe mode again. It seems like it wants to shift gears but somethings is holding or delaying in shifting. Had to pull over and reset it by turning car off and on again. This seems to happen around 4 and 5 gears.
