I'm borrowing a 1999 2500 cummins automatic 4x4. all of a sudden the speedo whacked out and the brake and abs lights came on. It's intermittant and only acts up after driving for an hour or so. After it starts freaking out every so many miles it flutters a split second then works fine. WTF?

 

probably a problem with the abs sensor in the top of the rear pumpkin, or its wiring.

if not that, then speed sensor in the rear of the tcase.

 

Give it back!

 

replace the RWAL sensor on top of the rear diff

 

How does your input have any value on resolving an issue?

 

he was only joking with you

replace the RWAL

 

He was making a joke, just ignore him if you didn't find humor in it. Like the others said, check the RWAL sensor.

 

I'll order a new sender up tomorrow. I just hate posting snypes that have nothing of value to offer and only talk to hear themselves talk. Waste of time, and efforts!

 

Well, I would suggest you develop either a thick skin, or, a sense of humor about the whole thing, as it happens on a regular basis.
