Well, a couple variables here.. first, the question is whether you're talking about the speed sensor for the speedometer, or the wheel speed sensors for the ABS. For the former, if you've changed tire size, rear end ratios, etc, then it'll depend on the age of the truck... on trucks with mechanical controls, you replace gears in the speedometer itself... on trucks with electronic controls, you have to change parameters in the ECM.
If your speedometer isn't working, then mechanical trucks will have a cable running from the transmission to the speedometer, and that'll likely have to be replaced. Electronic trucks will have a speed sensor on the top of the transmission output which has probably gone defective.. however, check the wiring first, rather than just throwing parts at it.
If you're talking about a wheel speed sensor for the ABS, ensure that they're flush against the exciter on the back of the wheel spindles, and that the wiring isn't damaged.
If you're trying to adjust speed settings, then you probably have an electronic truck, and that'll require parameters in the ECM to be changed.
