You really do need to give us more information. How many pulses per revolution does your drive train give? How big are your tires? What is the rear end ratio?
I doubt the drive shaft gives just one pulse per revolution, but assuming it is just one (1), then 6800 pulses per minute = 6800 rpm. If the rear end is 4:1 (I know that would be very unusual), then the tires are rotating at 6800/4 or 1700 rpm. Now, if you have a common 14" tire, the rolling circumference is 66" (**broken link removed**). 66x1700/12 = 9350 feet/minute = 156 feet/second = 106 mph. Obviously, that is not 10 mph. Something is wrong. Even if the final drive (before differential) is giving 4 pulses per revolution, it is still a lot more than 10 mph.
How about giving us some real data to work with to help troubleshoot this problem?
