* Speedometer Flatlined Today*

[purplehaze]

well i was having a problem with my speedometer needle for a while, it would tend to bounce every now and then. i cleaned up the connection on the tranny and had same results. now just today it was working fine and then just went dead on expressway and hasnt moved at all. what could be the problem? the speedo gear??? thanks guys.

have u tried pulling the gauge cluster out yet? if not try that and check the connection to it or just check it in general
(two plug ins on the back from the wiring harness, the little module on the back that controls it, and the whole back of the cluster its basically a circuit board) just a suggestions, goodluck hope you can find the problem and get it fixed.

Speed sensor is a easy check. If you've got access to a lift it, just put the car in the air and pull the sensor out and look at it. Its on the drivers side of the trans, about 3/4 of the way back on upper side a little bit. Its only has 1 screw holding it in I think. The gear is plastic, so it MIGHT have sheared the teeth off over time. Not sure how likely it is, but you never know.

yeah if it was something electrical your needle wouldnt necessarilly bounce. i went through this problem twice, the first time the needle bounced for a while then stopped. the plastic gear on the sensor that goes into the tranny was bad, the teeth sheered off, once one of those teeth comes off, it puts stress on the next tooth cause the tranny gear slams onto it instead of it being inline. The second time my speedo just stopped altogether without bouncing and it turned out my sensor was bad. so its a easy fix and im willing to bet tahts all it it. the chances of your speedo being bad or the wiring is slim, esp. if youve never taked your instrument cluster out. good luck

going to check the sensor on tranny. i think it may have gone bad since its still the original from factory. thanks guys.
