2017 Silverado LT Z71 with 113,000 miles
I was driving home a little bit ago from a nearby place. It’s only about 3 miles away and a straight shot there and back. While I was driving I noticed my rpm needle bouncing and the truck kind of pulsing in power. I thought this seemed really weird and rolled down my windows and heard a faint noise I haven’t heard before. I pulled over even though I was only about a mile away from home and shut the truck off for a bit and started it back up. The noise continued although it was pretty faint and I decided to just shoot the rest of the way home. When I got home, I crawled underneath and heard the noise slowly get worse over the span of 5 mins. I can hear it the strongest around the oil pan/ transmission pan area but I have no clue what it could be. It kind of sounds like a clicky whine that’s really loud. The noise happens when in park so I’m thinking it’s not the transmission but I could be wrong. I just bought the truck about a month ago and I hope I didn’t get screwed. I’m hoping someone can help me figure out how to diagnose it or help me figure it out in general. Thanks

I have attached some links to a YouTube channel that should have the sound and video of where it appears to be. https://youtu.be/4_-h2mrf0pg?si=y1_llfuU0bApDpN2

Makes you wonder if they even read the thread. I doubt they will have nay help on a 7yr old truck with 113k on it. 

 

BTW, Calvin, I would stop running the truck and have it towed to a trans shop. The more time you run it the more damage is likely being done. Odds are the torque converter has failed which will destroy the rest of the trans in short order.

I haven’t ran the truck since and I’m hoping that I was able to catch it early enough to save the trans but that’s probably a loss. I think it could be the torque converter but have had a couple people say that it could be the oil pump or trans pump. I’m not familiar with them but either way I think it’s something a shop is going to have to diagnose for me

Did you ever get a resolution to the issue.  Mine is making the same exact noise and I am going through the same process.  Thanks in advance.

    • Your tire pressure issue may just be batteries, you can reset them using tge Ing switch (I think) and the owner's  manual. ChatGTP will b e a faster, better help than Google.
    • The thinking is that starting out in a higher gear makes it easier to avoid applying excessive torque when pressing the gas pedal. In a modern 4wd truck with 4 low and a limited slip or locking rear end, I would use 4 low and try to crawl up the ramp. Sometimes if they are too slippery, you have to back up to let the boat have some bouyancy, and then accelerate briskly to get some momentum to help you pull the through the slippery parts. 
    • I have a Retrax pro that I first had on my 2020 chevy and transferred it to my current GMC.  It stays in the garage most of the time, so hard for me to judge it's long term weather resistance.  It still works perfectly, been very durable.  It doesn't see oil patch usage, but it's not a mall queen.  It keeps most things mostly dry (small leaks) and the security of it is enough to slow someone down but not keep them out for long.  I would buy one again, it works for me.     
    • Thanks to the convenience of Amazon, I was able to get a few things done to the truck today.  I installed Carquest Premium oil and air filters with five quarts of Mobil1 High Mileage 10-30 along with a quart of Pennzoil Platinum 5w-30 I already had.  The latch for the flip up center console lid was broken so I replaced it along with the power mirror switch.  I found my push retainer assortment this morning and reattached the plastic under the bumper and it was only held on with a few screws and retainers.  Then I programmed a new remote keyless entry fob so I can lock my dog in the truck when I take her out with me (I've got to keep the air going for her since it's been in the 100s).  Finally, I ordered some LED interior bulbs and replaced the reading lamps.  The front lights are working fine while one of the back lights only works intermittently and the other not at all.   While under the truck, I found the source of at least one of the noises: the sway bar links need replacing.  I ordered a set of Suspension Dudes links with Code Red bushings.  Never heard of them, but they're made in the USA and have decent reviews.  While making yet another Amazon order, I went ahead and added a set of front tow hooks.  I went with red, since that's the color of the sway bar link and bushings and it should look decent enough on a black and chrome truck.  Speaking of which, it doesn't bug me much, but the passenger side mirror has a chrome cap while the driver side doesn't, so eventually I'll make them match one way or another.  Oh, and I ordered a $20 TPMS reset tool.  No idea if it will do anything for my sensors but it was cheap and will work for the Ford Transit Connect as well.     For tradition's sake, I ordered a new oil change wrench.  I kept the Snap-On 9/16"x15mm GM wrench I bought when I was 18 in the 2006 GMC from the time I bought that truck until the truck was lost.  While I was tempted, there's no need to spend $80 for a new SO wrench, or even $50 with shipping for a used one on Ebay.  I just bought a Duratech 15mm extra-long ratcheting wrench to do the job as needed.  It works, and if I like that wrench enough, I'll buy the set.  
    • The recall is for exactly this issue - those drain holes combined with the limited environmental capability of the tailgate electronics card inside the tailgate were a problem. The “safety issue” was the potential for the tailgate to spontaneously open, but all kinds of tailgate misbehavior can occur from water contamination of that control card.    There is no real fix yet. The initial recall just disabled the tailgate. Later, when parts became available, they would replace bad parts with new parts of the same bad design. My dealer is going nuts because the few times I let them get their hands on my truck, my tailgate is off due to a slide-in camper installation. They really want to cut my tailgate wires, but I won’t give them the chance. I will let them get their dirty hands on it when a real fix (redesign) is available.  My tailgate, which works just fine with sealant plugging the drain holes, will remain safe in a dry storage crate until then.
