Speedometer Quit

Recommended Posts

Not sure if I'm in the right topic section, so , if not, let me know ....

I had posted a problem within the last several weeks about air leakage in my fuel system. While trying to solve this problem, I noticed my speedometer would register 25-35 mph while I as standing still. My mechanic had instructed me to put the cruise on fast idle, which i did, and then i noticed this problem. It wouldn't reset. Then when we found the air leak and solved it, after running the engine for a while I noticed the speedometer had reset to 0. Went out on the road to go camping....... no speedometer reading..... just 0

I have a Cat 3126b and a Allison 3000mh with the pushbutton shift selector.

On my short 2 day (60 mile) the Allison seemed to work ok. The engine brake,cruise control and shifting seemed OK.

Can anyone address this issue?

Thanks

I have the same issue speedometer mine is electronic and zero is now 45 MPH, so I have to keep subracting 45 from 120, etc.

I think this happened when I hit the speed control by accident at the same time I turned on the windshield wipers.

Standard GM setup.

Any thoughts on a reset or it is toast?

Thanks all,
