If hasn't used vacuum to shift then your transmission one is controlled by a cable and the valve body, it probably just needs a good filter and fluid change done on it right now, its not picking up the fluid fast enough to enter the transmission, and this is causing it to not shift right, have it changed ,and have the bands adjusted while your at it, and it will shift a lot better. Good luck, hope this help.
