i have been having problems with my speedo lately, i just got the car this october and really dont know what was put into it, i know it has gears and assume they are 3.55's, i turned the tires and the driveshaft spun about 3 1/2 times. the speedo wasnt working so i pulled the VSS sensor off and there was no driven gear to be found, there is a 7 tooth yellow drive gear.
so i went to mustangs unlimited today and used their speedo gear chart, according to them, 3.55's in a manual tranny use a 20 tooth black driven gear. so i bought it, it was all of 7 dollars. installed it, and my speedo works, but its about 20mph off... when im going 60mph, my speedo reads 80mph.
i was looking at my friend andy's gear today, his is red, and he has 3.55's too, and his speedo is dead on... but mustangs unlimited says red is 3.73...
what should i try now? if the car had 3.27s would it make the speedo read higher than im going or would it read lower??? should i get 3.27 driven gear and try that? or get the red one?
my friends tranny also has the same 7 tooth yellow drive gear... maybe i should get the red?
what do you guys think? how can i figure this out without buying all the driven gears at mustangs unlimited and breaking my wallet haha
