Hi I have a 91 first gen an my speedometer an odom/trip work fine then the trip and odom will stop working for a couple miles or so then it will work normal it shouldn't be the gears would it?

 

Usually the gears break and it never works again I have never seen one work intermittently.

 

Yea, idk I've pushed the trip reset once or twice but it worked since now it just works every now some one said to check the cable to the tranny?

 

If it is an intercooled truck there is no cable.

 

It's factory non ic

 

Does the speedometer quit working at the same time, or does it keep working when the odometer quits?

 

Speedo works

 

Hey, Duck,,, have the same problem w/ my 91.5,,, but I didn't rebuild this one ,but I just bump the odom. button ,,it all works ,,weird huh.

 

I hit the trip reset button now it don't work at all so now I'm pretty sure I stripped the gears fml

 

I bought 2 sets of gears (about 3 yrs. ago), rebuilt my own,per. the sticky,fix'n to rebuild this one, check out the sticky.

 

I have a Auto 93 4x4 . My Speedo just kinda jumps every where even at idle. Im curious as to if my odo and trip is accurate now? Cuz they still work

 

My 92 speedo jumped around like that and it was the speed sensor wires rubbing the drive shaft and wore thru the insulation. Taped them and tied them up out of the way and no more problems.

 

I'm having the EXACT same issue. Speedometer works just fine but the odometer stops working for a couple hundred miles at a time...sometimes 20-30 miles at a time. no real pattern. I checked my gears and they are just fine...no missing teeth or cracks. surely somebody has some insight
