..."sport" mode automatically.? The "sport" mode is used for inclines and doesn't allow the tranny to shift to a higher gear so it can traverse hills more effectively. At highway speeds the "sport" mode will turn on automatically and as a result the engine begins revving very high and the tach almost red-lines. I have to stop the car and turn it off to "reset" the thing. Can anyone tell me what the problem is, how to fix it and how much that might cost?
