Odometer stops on 96 Pathy

[Pauly321]

Okay so I noticed this happening for awhile now. When I drive over 45mph the odometer/trip meter will eventually stop turning completly. Once the truck is off for awhile usually over night it will start working again. Once over about 45 it will stop working again. It is really a weird problem becasue I have gotten it to start working before by shifting into 4wd. My check engine light is on due to no overdrive. I still haven't been able to figure out that problem. I am hoping that the odometer problem could have something to do with this. I know that everything is electrical for my dash so I am wondering what I should check first. The speedometer and tach have always worked fine so can I rule out the speed sensor?? The only code that comes up is incorrect 4th gear ratio, due to overdrive not working. This problem is driving me nuts I can't figure it out. Somebody help me out!

Well, it sounds like the speedo/odometer is failing. The speedo and odo are linked together and one can fail independantly. You may want to removed the cluster and tighten all the little brass screws on the back and see if that helps.
