Check the fluid first for both level and quality. If the fluid is not dirty or burnt and the level is correct, shift problems of the type you are describing are caused by solenoid failures, a defective valve body, a problem with the electronic transmission controls, occasionally a throttle position sensor, internal transmission hydraulic leaks and clutch pack (including clutch piston) failures. The exact cause will depend on what a real time scan tool reveals and also basic pressure testing of the hydraulic pressures in the transmission at the various shift points. I would recommend requesting a transmission diagnostic to identify the specific failure point.
