What's up, so I bought a 2004 cobra with 21k miles on it 6 months ago. Previous owner beat it to shit so I'm finding new issues all the time. The newest problem is my speedo reads 5 mph faster than what I'm actually going up to 45mph. After 45, it compounds. Example 70 on my dash is 63 on GPS. Previous owner put 3.73 gears in. But the speed sensor is located on the transmission, is the gearing causing my difference in accuracy? How can I remedy it? Thanks for the help
