Thread: shifting from first to second

ok sorry..I dont think i made my question clear. Let me try. First off the car runs fine and shifts like it should. What i am saying is that when i put it all the way down into first gear i want it to stay there. There is some kind of safety option that makes it shift to second. (probably to keep it from over reving) My question is how can i keep the car in first gear untill i manually let the shifter up to second. Hope this helps explain my question.
