REAREND PROBLEM?

08-17-2001, 08:13 PM

I HAVE A AUBURN PRO CENTERSECTION AND A REAREND GIRDEL WITH SINTHETIC OIL, AND I CHANGED THE SENSOR. THE PROBLEM IS WHEN I GET TO ABOUT 81MPH THE SPEEDO GOES WAKO,BEFORE THAT EVERY THING IS FINE! I WHENT TO A SHOP AND THAY SCANED IT,NO BAD COEDS. DOES ANYBODY HAVE ANY SUGGESTION! COULD I HAVE GOTTEN A BAD SENSOR, THAT MIGHT HAVE GIVEN OFF A BAD CODE THOUGH?

I think that speed sensor in the rear end helps to control your transmisson shift points, so i would think the trans would be shifting all crazy when your speedo jumps around.Did you have a problem with old sensor?

You may want to try posting your problem on the gen1 site, the only other suggestion i have is to check your sensor for any metal flakes that may be on it.
Sorry could not help,

That speed sensor really doesn't effect shift point..I took 2-3 teeth off my exciter ring, to the point where cruising down the highway I was fluctuating from 70-45.. This was happening each revolution of the rear end. The cruise didn't work and the ABS sensor contstantly pulsated each time I applied the brakes..These were pretty much the only symptoms, no real shifting problems however.

The biggest thing you have to make sure of when you change the rear end oil is TO MAKE SURE THERE'S NO METAL!! In the 8.8" theres a little recess right by the rear cover mounting surface..Get in there with your hands and magnet to make sure there's no metal. The reason my excitor ring went bad was a piece of my clutch ears got wedged in the teeth of the excitor and and wedged itself between the excitor ring and the rear cover, and sheared the 2 teeth off..

This things do fluctuate a small amount at high speed, but not more than 2-3 MPH. If you have any more questions email me at mailto:frisk@purdue.edufrisk@purdue.edu</A>
