I have a 97 Disco and my speedometer fluctuates after driving two hours on the highway. The rest of the truck is fine. I haven't notices any change in the idle. I think it is my VSS, from what I can gather off the site. As far as my alternator, everything seems to work fine, so I don't think that is what is going. Can anyone tell me what exactly the VSS does? Thanks | ||

I noticed the VSS when going up long inclines. My 97 disco acted normal in all others respects. Got my Vss from Discount for about $64 and change out in 15 minutes. Sounds to me that your VSS is the problem. | ||

does just your speedometer fluctuate? or does your actual truck's speed/power fluctuate? i do not think the VSS does anything to the instruments, so if you are seeing a fluctuation in the speedometer only, then probably not your issue. | ||

I am only seeing it in my instrument. The actual speed/power of my vehicle does not change. I am going to take the VSS off this weekend and see if it needs cleaning. But since everything is running fine, I don't know what it is. | ||

don't take off the VSS. it has nothing to do with your problem. | ||

So what is wrong with my Disco? | ||

could be a bad speedo cable or the speedo itself. | ||

There is no cable, I thought that everyting was electric. I don't think it is the speedometer because it has only done it three times. All three times it was while I was driving on the highway after about two hours. The last two weeks while driving around town nothing has happened. | ||

If your tach is bouncing too it is most likely your alternator getting ready to go. I replaced mine with a rebuild about 10k ago and some days my tach/speedo bounce for a couple of seconds. I'm going to bite the bullet and go with a Mean Green now. |
