Answer Hi Mack,
That's a new one on me.
Did you disconnect the battery?
I guess it's possible the ECM has something built into it to prevent odometer changing, but I haven't heard of it.
Could you swap fuel guages?
Do you have access to the ECM from the cluster doner truck? Might temporarily swap them just to see.
Another thing I would suggest is go to a Chevy lovers forum I belong to, and ask the question there. I am Fixitfox33 on that site, and here is a link that will walk you through signing in.
It's all free, and a great site. Here is a referral link.
