I have a '87 GMC Rally STX van, but I think the vehicle speed sensor is similar; The sensor is located just behind the speedometer in the instrument cluster on the dashboard. You access it by removing the instrument panel (carefully). You will need to disconnect the speedometer wire and the electric socket before pulling the instrument cluster out. The vehicle speed sensor is a very simple and reliable component. Not likely to fail. From what you say about the speedometer 'shutting off', I would be inclined to think there is something wrong with the speedometer wire. This component won't last for ever and is probably worn out. Unless your transmission is electronically controlled (don't think the '92 models were), I don't think replacing the speedometer wire will address your transmission problem. I believe that is sorted out within the automatic transmission unit. The TV-cable must be intact and correctly adjusted for the transmission to shift correctly. The TV-cable connects the throttle with the gear-box. Hope this is helpful information.
YOUR SPEED SENCER IS STARTING TO GO its located on the side of your transmission
occasionally experiencing frost and snow in the higher regions
The higher centers in the brain are located in the cerebrum.
there is a speed sensor on the rear of the tranny which puts out a pulse to the ecm this is converted to dc current to drive the speedometer faster the speed more pulses more pulses the higher the dc the higher the dc the faster the speed display
Well on my 1997 it is located on the output of the transfer case that goes to the rear differential.
Why does the speedometer on my 1998 cavalier drop a few MPH after some occasional shifts to higher gear? I.E. 3rd to 4th gear, speedometer would drop from 35 to 30 mph, without the vehicle speed changing, then go back up to vehicle speed.
slightly bigger tires
A hair over 78 mph (78.125).
Recommended size is 14" to 15". You can go higher to 16" but not recommeded. Note that when you go for bigger rim, the profile must be adjusted accordingly so that the speedometer stay the same. Otherwise the speed recorded in the speedometer is incorrect.
It depends on the plate maker and occasionally the number. Typically the lower the number the higher the value
If the object is freely falling near the surface of the earth, then the reading on the speedometer is always 9.8 meters per second (32.2 feet per second) higher than it was one second earlier. That number is called the "acceleration of gravity on earth", and your speedometer is a great way to explain it !
