I have a 1992 toyota with a V6, automatic trans. This truck will not change gears. Its stays in first gear no matter how high my RPMS get. There is a cable that goes from the trans. To somewhere?. I was told it was a detent cable and it goes on the throttle body, however it does not go to the throttle body only the accelerator cable goes to the throttle body. If anyone out there has any idea. PLEASE!! HELP ME OUT... thanks..
