Speedo/odometer faliure?

I may be missing something, but he has a mechanical spedo in a 97, a speedo gear is the only way to fix a speedo that is off..... I thought only 99+ cars had elec speedo's...... Again, I may be wrong here. My speedo is correct in my 98 and I don't know of any speed cal on it.... (4.10 gears were in it when I bought it).

The speedometer and odometer are driven by different gears. If they both stopped working its likely that it is an electrical issue and not a mechanical one. In my car the speedo works but the odometer and trip meter stopped working because the teeth on that gear are worn down. They sell the gears on ebay for like $39.

I'm not sure of the exact logistics of how it is converted from mechanical to an electrical signal, but a 97 has the gear in the trans which goes to the Vehicle Speed Sensor which sends an signal to the speedometer. You can either install a speedcal which taps into the VSS wires to correct the output for the rear end ratio, or install a smaller speedo gear.

The 99+ can correct this through the cars computer via a tuner (XCal, Diablo, Etc.)

Yes, thats the VSS..... drivers side of trans towards the front... right by the shift tower if i remember correctly

If your saying its not connected? Then that's definitely your problem.

me too

Let us know how you make out ......... or did you fix it already? haaa

The vss is on the drivers side . Here is a picture View attachment 270102
