Answer
Hi, Ralph.  This indeed could be a problem with the shifter.  If the transmission conrol module (TCM) is receiving a signal from the shifter that it's in the sport mode, it will not shift to the next higher gear unless it also receives the upshift input from the shifter or the engine rpm becomes so high that it's necessary for the transmission to shift to prevent engine damage.  

Unfortunately, the best way to check the shifter is with a scan tool capable of communicating with the TCM.  This will enable the person examining the car to see the status of all the shifter switches.  Often, when there is a problem with the shifter/switches, there are no diagnostic trouble codes set.  If you believe this to be the problem, your best bet is probably to take the car to the dealer for diagnosis.  

The "D" indicator not coming on could be related to a shifter issue, or the bulb could be burned out.
