1999 Fl70 Vin Number

Hi, I am new here and previously posted this under someone else's thread, but realize if I want people to actually see it, maybe I should post it as a new one.

Here is my situation:

I Purchased a used 1999 Fl70 to run a dedicated route with. The problem I have is the speedometer and odometer are not working correctly. The speedometer is showing me going faster than I really am and the odometer is racking up miles I have not traveled. I have read through the forums and found out how to recalibrate the speedometer, but my problem is that I do not know what the gear ratio is on this truck.

I found a sticker on the side of the dash that said some company modified the truck and changed from 275/80/r22.5 tires to 295/70/R22.5 tires, so am thinking the recalibration is much needed.

anyway, I would like to know if you can tell me anything about Vin#
1FV6HJAA8XHB40557 ??? If I can get the gear ratio, I have the rest of the info to get me where I need to be.

Thanks

 

Yes, liners have the dip switches on the back of the speed also. Once I find out the gear ratio I can recalibrate it.

Being old, set in my ways and made of shallow pockets I really want to try and recalibrate the speedo before shelling out food stamps to someone else to fix this.

If nothing else... since I cant find a way to run the vin# on my own, I will just take the number to a local dealer and hope they are nice enough to give me the info.

Thanks for replying though. Be safe out there... there are bears everywhere

 

WOW! Thanks a ton. They were super friendly and told me I have a 3.90 ratio.. YAY! I will do the speedo calibration and that should tell me if I need to take it in and have the ecm recalibrated or not.

Have a great day... you just made mine for me
