I have a 2005 Silverado and I have a problem with it being in auto 4wd as soon as I start the truck some mornings. I have a brand new dash actuator and transfercase actuator on the transfercase. I just fixed some of the wires that were exposed for the 4wd. I still can't figure out the problem.

Did you leave it in auto the night before?  I can do that with mine but we have different generations.  It seems to me this might have something to do with the transfer case.  Do you know which one you have?  I might have the troubleshooting guide for it or know where to get it.

Are you sure that it is actually shifting completely out of Auto 4whl drive? Find that mudhole and lets throw up some rooster tails and check this out.

No I don't ever put it in auto 4wd. And it's not in auto cause I can tell when it's in auto it grabs when I try to reverse

I've had problems with the 4WD selector switch on both of my trucks. My 96 wouldn't shift from high to low range, or if it did, it wouldn't shift back. My 04 would shift from 2WD to Auto while driving down the road.

 

I found that, in both cases, the switches had bad solder joints on the connectors. I removed the switches, resoldered the connections, and put them back in. That fixed both problems with no out of pocket expenses.

 

You can find many videos on YouTube to show you how to do the repairs to the switches.

I have a brand new dash selector switch could it still be something in the wire connector on it?

My stock acdelco one still did it before I switched it so I don't think that's the problem.

      The Peckish Synapse

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.

      2026 6.6 L5P oil cooler leaking oil at 4,000 miles

      By Brendan C · Posted

      New to diesel trucks. I happened to find my oil cooler leaking oil externally with only 4,000 miles on the truck. I didn’t realize this was an issue until I started researching it. Dealer is going to replace it under warranty but I’m wondering if there’s anything GM is working on to fix this issue. I’ve heard the oil filter used is the same as they use on their V6 motors and that’s what is causing the problems. Should I switch to a bigger filter or keep using the OEM recommended?

      Seems to be Missing a lot of Updates

      By Vu1can · Posted

      So, GMCustomerService:  Judging by the Update History pictured above, is this truck missing any updates that it actually needs. If it's just for the infotainment system, the radio is working fine and no trouble with SeriusXM. and Android Auto is working fine wirelessly with my phone. Some months ago, an update notice was sent to my truck. I approved the update and it finished saying that the update was successful, but it seems that whatever that update was, it didn't actually get installed - at least not if I'm to go by the Update History shown above.   So, again, are there any updates that this truck really should have? I've checked with my dealer but they're reluctant or commit to anything and if I want them to check, they require a $200.00 fee just to check it out and then I'd have to pay for the actual update(s).    Ignorance is bliss, and if none of the updates goes to fixing any mechanical discrepancies, I'll just leave things as is.
