faulty torque convertor.
Actually a faulty torque converter is a possible but least likely candidate. Not enough fluid is more likely, or a badly worn pump not capable of running minmuim pressure at low rpm.
If transmission is hydraulic, could be issues with throttle valve adjustment, or engine vacuum depending on the load and throttle being put on the vehicle at the time of the slip, or stuck pressure regulator valve.
If pressure is controlled by epc (electronc pressure control) solenoid, then epc itself could be failing, or one of the sensors that the TCM (transmission control module) uses to decide what it wants the epc to do, mainly the tps (throttle position sensor) may have failed, or is having wiring issues. Stuck pressure regulator valve is also a possibility

Would vacuum leak cause automatic transmission to slip on 98 Pontiac Grandam?
I don't think so. The automatic transmission is controlled by engine speed, vehicle speed and throttle position. A large vacuum leak could effect throttle position, but it would cause other problems more noticable than the effect on transmission shifting. a vacuum leak mpuld not cause trasmission to slip but a band inside transmission would cause the problem
