'00 1-ton 4wd speedo and tach

Wyley87 · 10-21-2009, 10:20 AM

ok guys my dad owns a 2000 Chevy 1-ton 4wd old body style. Just recently told me his speedometer and tach just one day stopped working. My brother looked at it and said all he found was the 4wd fuse blow so he replaced it. The truck is about an hour and a half away and im going over there on sunday to help him out. Any/all suggestions on what this might be are welcome

P.S. POST 400!

well thats what i was thinking but i didn't want him to got spend $45 on on and have it not fix it. Will this also cause trans mission shift issues?

Yes it would, because the tranny is not comunicating with the vehicle to know what speed your are going.

Wyley87 · 10-21-2009, 04:28 PM

i called my dad told him VSS he said he'd try it. Now we just gotta worry about the slew of codes that are in it. I'll have to let yall know what they are on sunday.

I agree the VSS is the speedo issue, the trans shift issue is probably the transmission speed sensor (about $40). I just replaced both on my 94 1 ton 4x4.
I hope this helps.

You're just going to get random thoughts from me because my good brain
is in the shop and it's past warrantee period. And I do mean period.

I would not replace anything without knowing the codes and doing a visual.
That 4wd fuse blew for some other reason than it was cranky.
This is a 4wd implying other than city streets. VSS is exposed underneath.
Maybe you have damage wires or loosened connectors below.
4wd fuse also used for Aux Batt relay if he has one.
VSS is homerun to ecm and effects trans & speedo,
but there is a second sensor, right?, so ecm can confirm gear ratio good.
Don't assume one that CAN is one that DOES. Reminds me of me. LOL

ok well i tell you what i'll do is call my dad and tell him not to buy the part just yet. I'll go look at it on sunday and report back to you guys what i find. and yes he has an aux battery. I gotta go out there on monday again anyway to change out my fuel sender.

I'm not saying it is or isn't anything for sure,
just pushing the troubleshooting idea (cheaper)

Otherwise only rich guys can fix trucks
when it becomes a parts-throwing contest.

well the funny thing is that his 4wd is on the floor not push button. So i dont see what ccould blow a fuse on a mechanical linkage.
