grinding noise when pushing in clutch on cold start

Hey guys,
I have a 2000 f250 7.3 with a ZF6. When the trans is cold in the morning and I push in the clutch (i have a remote start) it makes a grinding noise for a quick second and dims my lights and restarts my headunit. It just recently started and I have never heard of anything like this before.

Any help or suggestions would be appreciated.
Thanks!

Throwout bearing? Does it happen every time you press the clutch in until it warms up?

it only happens the first time and sometimes the second time i push in the clutch. i thought it would be a throwout bearing too but wouldnt that be all the time?

That would be typical of a bad throwout bearing... maybe yours is getting worn and it takes that first clutch application to get the equally worn grease onto the bearings? That lighting issue is odd tho. Is that consistant with the clutch issue? Does it still go thru all the gears ok?

Would be easier to diagnose if I could see and hear it for myself

I'd have the bearing checked and replaced before it seizes up and breaks the fingers off your clutch plate at an inconvenient time. Yes...it happened to me once :-)

figured it out. some some reason my remote start would try to restart the already started truck once i pushed in the clutch to disengage the remote start. it stopped making the noise because i gave it more time to disengage the remote start mode before i push in the clutch. replaced the module so this doesnt happen again. but thanks for all the input everyone. hopefully my over running clutch isnt hurt.

thanks
