got the gears redone is this normal?
I got 456's put in with a eaton on a 8.8 rear end. The rear end is on a 2001 ford ranger edge with a 4.0 motor. I know the spedo is off because when the governer kicks in at 92 i am only going like 83. Also when it says i am going 75 my rpm's are are like 3200. By the way i have an auto matic transmission. I'm wondering if there is a problem or just with that high gears and 35 inch tires thats my max speed. My overdirve on off button will flash after i drive the the truck for about 10 minutes. It was doing this even before i got gears. i was wondering what that was too. any help guys would be greatly appreiciated.
