there is a small piece of equipment that goes into the transmission that checks the speed. i forget what its called and where its located but thats the culprit. that or the wiring that goes into it. umm.. check your transmission, there will be a black thing that goes in, one bolt holding it down and right on top goes a plug with 3 wires. its called a speed sensor. check on that.
