I have a 1999 Tahoe LT  With the push button 4X4. Here are my questions.

 

OK.  First off I am a moron.  I was jut making sure that I would be able to change the plugs with out a problem last night.  Well they are a cinch like I thought.  So I put it back in and will get the New plugs today.  Well the moron I am I forgot to put the plug wire back on.  And the SES light came on.  Will it go off by itself?

 

Next.  I will be changing the Front and rear Diff fluid and the T-Case fluid.  I will have no problem with the Diffs.  But what about the Transfer Case?  It sounds simple enough but are there any tricks and or tips?  Also it looks like it is leaking a little bit right now.  Is there any where that they usually start to leak or could it just be from the drain plug?  And I think I am just paranoid but when I hit the gas I get a vibration feeling in the pedal.  I think it could just be my head because I saw the slight leak.  Or it could just be the motor vibration that I never noticed until I saw the leak.  It definatly does not slip and it has plenty of power.  I am hoping that it is only the fluid that needs to be changed to get rid of the drive line clunk.  Could the clunk happen from low fluid?

 

Oh and one mre thing.  My fuel pump sounds very whiny (sp?)  Is it normal or is it a sign?  

 

Later,

Brandon

1.  I would say if the light doesn't go off I would unhook the battery cable for a little while and see if that helps.

 

2.  I don't know

 

3.  It sound as if the fuel pump might be going bad, but I don't know.  But I don't know how loud your whine is.   :jester:

Thanks for the info  I was talking to a guy here at work and he had to replace his and it was no louder than the new one that he put in.  You really cant hear it when the truck is running.  Unless you are listening for it.  But you hear it when you turn the truck off.  Thanks again.  Anybody know about the T-Case?

 

Later,

Well my fuel pump got louder and was replaced under warranty, so I'd go that route if you can.  In regards to the transfer case, 1 of the solutions for the driveline clunk on the pickups was to replace the t-case fluid with the new blue juice that GM has.  When doing so, they recommend draining the old, refilling with blue, driving a mile or so, then draining and refilling again.  I did it, and had my splines lubed, as well as the nickel yoke and she's quiet for good now.

      The Peckish Synapse

      By Grumpy Bear · Posted

      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.
