I have a 94 GSR, and for a while now, the Speedometer has been jumpin, especially when I get on it, could this be my VSS, and if so, where is it, I looked in my Chilton, it just told me what it looked like, and not where it is located.

 

I have the same problem the speed sensor is on the top all the way twoards the firewall on the tranny. If you look at the throttle body its right below that on the top of the trans.
