It sounds like the VSS (Vehicle Speed Sensor) has failed. If the VSS fails, it can cause the symptoms you are describing. Check the wiring and make sure your VSS is properly plugged in before you replace the VSS. Where the VSS is located can vary depending on Make Model and Year. Check your vehicles… Service Manual (Available from auto parts stores, commonly referred to as a "Chiltons Manual" or "Haynes Manual". ALLDATADIY is another good source) for more information. Some vehicles do not have a Vehicle Speed Sensor, a common example would be a Generation 3 Ford Taurus SHO. The SHO uses the ABS wheel sensors to generate a signal to the computer to calculate speed. If this is the case with your vehicle, it is recommended you take your vehicle to reputable shop for servicing, as the ABS system is a complex and important safety system for your vehicles safe operation.

Why would the automatic transmission not shift out of 1st and the speedometer stop working on a 1992 Toyota 6-Cyl 4Runner when the ignition timing is retarded?
Answer . Try replacing the vehicle speed sensor (VSS). It's held in place on the side of the transmission by a single bolt and it has a single electrical connection. I had the same problem, and this cleared it up instantly!
Answer . \nthere 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
What could be wrong if a 1995 Ford Escort LX speedometer does not work and the automatic transmission will not shift out of first gear?
I'm having the same problem. Seems to me it's something in the engine wiring harness. It happened once and my daughter played with some of the wiring and it was fixed for quite a while. Recently, an auto repair shop was messing with the wiring and it's back doing the same thing again. Speedo not wor…king and it hangs in 1st gear and shifts erratically.. I have had this problem also and it is a easy fix. Replace the speed sensor. There is two kinds one with a red gear and one with a white. So take it out first before you go to get one. You can find the speed sensor on the back of the Transmission the speedometer cable goes through it you will need a 10mm wrench and that is it.. if its stuck in 1st the gear box is probly buggerd and as the speed sensor is directly attached to the gearbox it probly still works just need new box ( Full Answer )

On a 2005 Chevrolet Malibu the instrument panel backlighting are working fine but all the gauge indicator speedometer and tach are not working and the fuses are fine. What could be wrong?
I had a Dodge Neon that periodically all the guages went to 'zero'. Had it in the shop several times for nearly 15 days total, and it turned out that the battery connections were a little corroded and loose. I would suggest checking to make sure your battery is operating correctly and is connected c…orrectly.. Check any of your brake lights/running lights - If they burn out then this condition arises.

Need to replace the neutral safety switch on the side of the transmission But need someone to scan the trans. First with a engine scanner. To make sure that is the problem. It could also be a bad speed senser.
You may want to check the fuses for the lights. If that inst the case than it has something to do with the wiring which is a big mess. Or check the bulbs. Check the simple stuff first before going drastic.
could be a rusted out tranny line or a disconected vacumm line.. or possibly the madulator valve went out.. or even more possibly your tranny is shot.. i would try looking at all the lines and if they are all intact try replacing the modulator valve which will cost less than 15 dollars at any auto p…arts store.. and if all that didnt help it to shift i would scrap it or find another cavalier with the same engine size and do a complete transmission replacement..

\ncall the click and clack brothers on npr on car talk. they should be able to help you.
You need to have the trans computer checked for trouble codes. You will probably have an output speed sensor code. The output speed sensor is the two wire on the front of the trans on the far driver side.
Speed sensor on Trans, or buffer behind dash... OR, any broken wires in this circuit. Very common problem on this and many other vehicles.
If both the speedometer and odometer stopped working it is probably the speed sensor in the transmission gone bad. If only the speedometer quit you may have to replace the dash cluster with a reconditioned unit.
Can you use park, neutral, or reverse? If so then your tranny is in limp mode. The only gears that work are 2nd and reverse. Check the cable to your tranny and see if it is plugged all the way in. If it is then you have other electrical problems and need to have your truck looked at. I'm not sure …if an 89 still has a vacuum modulator on it or not.

Hopefully the simple solution would be the fuse 15a for the speedometer. If the computer doesn't read the speed, the tranny doesn't know when to shift. If the fuse is alright, you then need to check the speedometer sensor located on the rear axle hub. Check connections for corrosion and cable for da…mage. After that, good luck !! ( Full Answer )

Check the fuses, if fuses are okay, it is probably the VSS (Vehicle Speed Sensor) or wiring to it at fault.
