Thanks for that info Pinnacle. My '16 Silverado 5.3 has the shake. Comes in starting in the low 70 MPH range. Is there a part number or item number for the Mobile 1 trans fluid that you mention?

 

Also, can an independent shop do the fluid flush, or does the truck need to be plugged into a dealer/GM computer for a reflash after the flush is completed. I'd like to avoid the dealer if possible due to no to little faith in their abilities.

 

Thanks again

Take that with you to a gm dealerMC-10163890-9999.pdf

Well folks, I did it. After all the failed attempts at the Chevy dealer I traded it in for a 2015 Ram 1500 Larame. I have to agree with the other folks on here that have done the same thing, it was th

Apparently you and the other customer reps don't care. If you or GM would care y'all would put more effort in the matter. Just coming on the forum and stating the same repetitive posts and being a 3

Well I have some good news and bad news about my truck vibrations. Good news is that my truck has a significantly less vibration at speed. The bad news is my truck has significantly less vibration. Fo

I’m experiencing the same issue 86,000 km 

- lowered air pressure 32PSI … some change 

 

riding on the Denali 22” rims .. feels like it’s in the right front .. then left .. 

 

spoke with a neighbour with a similar truck and advised me that the rear stock brakes grab and transfer the pulse through the aluminum driveshaft to the front and GM has shown him supporting documentation..

 

rotating tires today will update post soon 

also have read transmission service could help the problem

I have a 2018 Silverado High Country 4x4 with 128k miles.  It started to shudder just recently.  Definitely feels like the driveshaft is unbalanced, but doesn’t shudder/shake/vibrate all the time.  I have no idea what makes it start or stop.  I had new tires installed, alignment done and even had the wheels rebalanced.  Three different places said the steering and suspension is tight and didn’t find any problems.  I’m hoping GM does a major recall on this problem as I cannot be the only one with the shudder/shake/vibration.  If it’s the driveshaft, why is it happening after,128k miles?

Could be that something is just wearing out

You say you had tires rebalanced. But did you have Road Force Balancing done or just traditional balancing? It does make a difference.

Do you have the 6 or 8 speed? Have you changed your trans fluid and filter lately?

Not sure which tranny it has.  No, tranny not serviced yet.

Some people have had their trans fluid and filter changed and reported a positive difference in the issue you’re having.

There was a TSB that came out around 2016 ~ 2017 for the tranny flush and replacement with Mobil 1 Blue Strip I think it was.  I had it done for tranny shudder problem which it fixed.  It also reduced but did not eliminate low speed hard shift problem between 1st and 2nd.  For some, torque converter replacement was necessary to eliminate shudder.  About vibration problems; I not aware of any single fix for that.  If you read back through the hundreds of posts you find the root cause blamed on virtually every part on the truck.  I don’t think it was ever eliminated from this generation truck which is 2014 ~ 2020 or thereabouts.

I had the shake in my 18 Silverado at 45k miles. Chevy dealer replaced the fluid with Mobil One under warranty and shudder completely went away until about a month ago. Just over 90k and intermittent shudder at 40, 50, and 60 mph has returned. Doesn't seem as severe as before. Doesn't happen over 65 mph. Rotated tires with no difference. They are newer Michelins with about 15k on them. Wondering if fluid has separated again? Saw someone mention rotors. Mine still look great and pads are original. Most of my miles are highway. Any thoughts?

Is the vibration occurring when you’re accelerating or braking? If it only happens when you’re braking then the rotors are warped and need replaced. If it’s doing it while accelerating, it’s something else.

      287,500 Mile Service   8/13/2026   Reset Fuel Trims   Since the work done in the previous post there was a good improvement in response in all areas except right after a fill up where the LTFT would go -20%+ for about four miles while the STFT was near neutral. Before the work they both went very negative for a few miles after a fill up but act normal thereafter.    We did a systems check of the vapor recovery system for functionality and ability to hold a vacuum. That checked out fine. But this doesn't mean the charcoal canister is dead in the water. Testing that is next up. For now the reset of the fuel trims.    I intentionally shorted the fill exactly two gallons to eliminate any chance of filling the canister. On start up the trims were behaving normally until I got up and rolling where the LTFT went -10 / -11%% but the short was + 2 to 0%. Within a mile the the STFT offset the LTFT and by 2 miles they were neutral. HUGE improvement but still not hunky-dory.    I'll watch them for a few days. Perhaps another tank where I will fill completely to 'first click' and compare. Meanwhile on the hunt for a new canister and I'll toss another purge value at it for good measure. Pending the outcome of the canister test that is. Progress of any kind is welcome.    Fuel economy improvement with bringing hole #3 back to the living was a noticeable bump to the positive. Even on the few miles I drove after the refill I already see another bump up by the trims reset.     She's purring like a kitten with a warm bowl of milk.    BTW, adding 50 rpm to the idle took the majority of the negative timing out on cold start up and leaned the cold idle. No longer burbles in the cat. What a dumb way to heat a cat.

      Yeah, shame I can’t really get that filter easily anymore. Running a PureOne. Your fave!    TAN would be neat to see. Confirmation I ran it too long probably. 🤣

      Roll up bed cover experiences

      By superdave160 · Posted

      My son and I both bought new trucks in 2017. Both of us immediately put Truck Covers USA American Roll Covers on our trucks. My son still has his truck and it never sees the inside of a garage. We live in Alabama, so not much snow. My truck was my daily driver and was in the garage when I wasn't driving it or at work. No issues with either cover even after almost 9 years. About a year ago I sold my truck to my brother and bought a 2025 Silverado 2500. The second thing that I put on that truck was a new Truck Covers USA cover. They are very well made and have a very positive locking system. I looked at a Retrax and my concern was the way that the cover locked to the rail. BTW, the first thing I put on the new truck was step bars. Those new trucks are high!

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By superdave160 · Posted

      The Allison 10 speed torque converter doesn't "lock up" like the previous transmissions. It has 4 operational modes; open, slip, transition from open to slip; transition from slip to open. I have an Edge CTS3 monitor and I monitor transmission torque converter slip. Step on the gas and you get a little slip. Take your foot off the gas and you get a little negative slip. I have not found a way to display the torque converter mode beyond that. My Edge CTS3 also displays something that our trucks should already display, the current gear. I also monitor throttle body position and engine load. If I see the engine load getting too high, I'll manually drop a gear.

      Nice result. Your filter is working well  I'd have like to have seen the acid number for this sample. Curious type that I am.
