I searched, but I didn't find the answer. I'm not sure this is in the right spot, but here goes. I just bought a 97 Cheyenne, 4.3 v6 and 4l60e transmission. The speedometer reads 0 when sitting still, but quickly pegs out at 100. It reads about 60 when the truck is going 30. By the time I'm at 50, the needle is pegged at 100. And it stays there until I slow down, then it reads 0 when I'm stopped again. And it reads consistently, no bouncing or fluttering, and the movement is proportional to the movement of the truck. It's just way too fast. Any ideas? Truck is completely stock, 265 75 16 tires. All other guages seem to be working normally. Thanks.
