Common problem or being fed bull crap?

I recently bought a 2018 chevy Silverado 1500 
5.3L 2x2 double cab brand new. I bought it with 
the intent of pulling an older two horse straight 
load that when empty weights 1000 pounds (yes 
it’s been on a scale). The horse that goes in it 
weight 970 pounds (same, he’s also been on a 
scale lol) and with tack we’ll say the total weight is 
3k lbs on a fat day. My issue is, when pulling a 
trailer, and I mean any trailer including the sketchy 
5’x9’ uhaul flat beds, at certain points it will start 
making a noise. I can’t pinpoint where the noise is 
coming from and it usually happens while cruising 
between 55-65mph. It sounds like you’re driving 
on the rumble pad on the side of the road and on 
occasion will also feel the same way. This happens 
with an empty trailer and loaded trailer, but not 
consistently. It has been into the dealership twice 
now and while they’ve replaced the air box and an 
exhaust valve they are trying to tell me that it’s a 
normal and common sound and problem, and it’s 
the ergonomics. I know several people who own 
Chevy trucks and none of them have ever 
encountered this.  So my questions. Is this a 
common problem anyone else has experienced? If 
so, what was it? Are they trying to blow me off and 
blow smoke up the pipe? Any help would be 
greatly appreciated as I’m deciding how I need to 
proceed.

Watch to see if it happens when the AFM switches to V4.  What you're describing kind of sounds like the exhaust drone.  I've had a 2014 and a 2018 and it's much more pronounced in the 2018 than it was in the 2014.

Sounds like what a lot of people describe when the torque converter is bad. GM used to recommend a double or triple tranny flush, but now they said there is a new fix that was supposed to be available last month but everyone is still waiting to see what that “fix” is.

do you have the 8 or 6 speed?

It’s an 8. I believe it happens in v8 mode. Usually when it happens it catches me off guard and I check the trailer first then my other gauges. If it’s exhaust drone would it happen intermittently? I’ve never had a problem like this before but this is also the first Chevy I’ve owned.

What they have done is beat the lemon law. Long as they make an effort to repair they can have a good chance of keeping you stuck with that truck in court.

8 speed transmission and rumble strip feel is almost always the torque converter. Repeated flushes fix it temporarily. I believe the long term fix is a new torque converter.

Long term fix is better ATF.

Fluid Exchange

The TCC shudder condition is related to moisture content in the transmission fluid. The current fluid tends to be hydroscopic, or absorbs moisture, which increases the chance of TCC shudder. There are three different fluid exchange procedures to follow, depending on vehicle application, so that an acceptable concentration of the new HP fluid is achieved in the transmission.

I assume you have tow haul on..  It sounds like you are hearing the V4 drone.  I hear it with my smaller flatbed trailer on but the travel trailer is heavy so I only ever here it wend going down hill. The engine braking is much louder.

 

Don't get an intake the drone is louder without the factory intake on.

 

I have an intake so it just ignore It.

 

You can get a range device to disable AFM..  don't need it on all of the time you can just put it on to tow.

Yes if it’s only happening in V4 mode. There’s a flapper in the exhaust that opens and closes with back flow pressure. The test to see if it’s what you’re hearing is drive in M7 while towing your trailer at the speed you here the noise. M7 will keep the truck out of V4. The other test would be to use a hose clamp and clamp the valve open then see if it changes or eliminates the noise pulling the trailer. You said they changed a exhaust valve? Is this what they changed? If so probably not your problem.

This is crazy!!  Back in the day- - - before computers and such, I was pulling my horse trailer with my roping horse inside of it.  Just went to dual exhausts on my 1969 F-100 (390 ci & C-6 Tranny)  Taylor Bo (Horse's name)  was going crazy in the trailer and he never did that before.  I didn't know what was going on..  A friend told me to ride in the trailer while someone else was driving to see what his problem was, yup, it was the exhaust noise.  Ended up running the pipes out to the side in front of the rear wheels.  

Want to know how your horse rides in a regular trailer, just ride in it while someone else drives.  Guarantee you will change your driving!

      Some Assembly is Required

      By Grumpy Bear · Posted

      Average Assembly 4.8%   That's the likelihood of a light duty vehicle reaching 250,000 miles. Link below has the stats on this. Among pickups the 350 series (Dodge)  and higher (450 Ford) are most likely and nothing American built in the lighter trucks pegs a number higher than the overall average.  200K and up is the stomping grounds of Asian vehicles. Toyota Sequoia the leader at 39.1% probability.      https://www.autoweek.com/news/a68886903/vehicles-most-likely-to-last-over-250000-miles/   Likelihood drops dramatically at 100,000 miles of reaching even 150,000 miles. 250,000 is deep in the tail of the curve.    I've been told by the 'experts' that I don't need oils of the caliber I use. My high viscosity is damaging my motors. Ash content it to high and WILL foul plugs and kill cats and O2's. I don't need that much ZDP; my choice is over added and not cutting edge. I change it to often. I baby them to much.    Three Honda's reached 200K + and none used oil. All Red Line motors. All sold to friends or family. One Toyota reached 300K using oil, Pennzoil. Dizzy 300K using QSUD until it cashed the rings at 80K then whatever but often ever since. Did you know this engine still sports the OEM timing chain and is dead silent? Pepper spitting into the wind short of 200K, Red Line and changed often. Uses zero oil. A HPFP and a pinion seal. Still using most parts it left Fort Wayne with. So 50% of my vehicles have gone past 250K and 100% of the last half dozen past 200K. Of these two using "shelf oils' did so using abnormal oil and the four that used a premium boutique oil did not. There might be something there the experts have missed. 🤔

      “Service Emission System” & “175 miles until “65 MPH Max Speed”

      By ManyCamaroz · Posted

      It's not that it sits for extended periods. I drive it every couple of weeks. However, I did consider draining the DEF and replacing it.    Don't you get a "Poor quality DEF warning" if its bad?

      Try draining the def and relacing with new if it has been sitting for a long time. Def does go bad after a little while.

      2015 Silverado with HUD retrofit/upgrade.

      By Thestonedone · Posted

      Thanks @Viktorrocks15 if you are still out there.   I followed your instructions and worked out great, went to the scrap yard and procured 2016 escalade cluster, hud, bezel, and switch. Got lucky and found a Camaro in the u-pull with the HUD bezel.   I made my own harness with these diagrams: https://www.gmupfitter.com/wp-content/uploads/2022/10/23_Escalade_Escalade_ESV_Electrical_Body_Builder_SM_en_US_2022OCT25.pdf   I used escalade cluster because its the best one that will work IMO. Still need to get it programmed but it looks really good.
