I have a 97 Tahoe &speedometer is 10 mph fast wheel and tire are factory size and I’ve already changed the VSS in transmission..
What can I do next to correct this problem? 97 Tahoe 4x4 5.7 Vortec I’m getting doesn’t have drac.
Does anybody know if it has one or not and where it is . Or what else could be causing my speedometer to be 10 mph fast.
