I drive a 2016 Silverado LTZ 4wd

 

I recently fixed my vibration issue, I found it was a faulty Torque Converter... It shuttered and shook at different speeds but not constant. GM warranty replaced TC and balanced tires and all Vibration was gone... I now love my LTZ....

 

PLEASE for those feeling my frustration check this out. I was about to use the OHIO lemon law to dump this truck but now all is right in the world again. If you need to PM me and I will scan and send the GM repair order.

 

Also IF your a internet surfer please spread this word as I am not going to, but felt it my responsibility as a Chevy Truck guy to post this.

Thank you for your input! I have the same problem as you and it is inconsistent at certain speeds over 70. Sometimes its there an sometimes its not or its more or less. I have efi live tuning and i had the problem before i did any tuning. I got my tune and flashed it and the problem seemed to have gotten worse which was puzzling to me. After 5000 miles or so it went back down to a minimal vibration. I updated the tune i had on the truck to a less sensitive throttle response. As soon as i hit 70 after the flash the vibration was horrible! So Im at a point where i don't only believe the torque converter is at fault but I believe it is something in the way it locks up at certain speeds.

Also might i ask if you have the 6 speed or the 8 speed transmission?

It is an 8 speed transmission... And 3000 miles since the TQ was replaced and not a single problem.

 

Sorry for the lack of reply but been out of town. There really is no sense posting the work order as all it does is prove I'm serious.

 

I am very happy with my truck now and was ready to trade it in.

 

Best to all...

New Member here. Found the site when I was researching the Chevy Shake. I purchased a used 2015 Silverado just before the end of the year. Beautiful truck....I've waited so long to get.

 

The first week I owned it I was in town all week....never going over 50mph.

 

Since then I have started back traveling for work and I am shaking all over on any speeds above 65.

 

The console vibrates and its unbearable. I have 34k miles so I am still under the factory warranty. I also purchased the extended warranty to 90k miles.

 

I am seeing drive shaft and torque convertor as the most common fixes. Would you just ask the dealership to test drive and try those fixes? Sounds like that might be met with resistance.

 

Thanks for any advice

I would definitely post on that thread linked above. This thread was made to discuss fixes that worked. The journey to finding your fix would be the other thread. If you're under warranty though I would absolutely go into the dealership as this is a known issue. Good luck!!

I have had my 2017 for almost a year now. It has very recently starting vibrating very badly at speed between 30-80mph. It feels like driving over a cobblestone road, but intermittently. Because I have added several mods I went to a friendly shop that gave me a free evaluation. They concluded it was definitely not wheel/tire balance issue and most likely a drive train problem. As such they advised I take it into the dealership for warranty.

 

Truck: 2017, crew cab, Z71, 4X4, 6.2L and 8spd

 

Mods: CAI, RC 2" leveling kit (front & rear) and 20" wheels w/Toyo ATII 295/55 tires.

 

I have serious concerns they are just going to side step the real issue and blame the non-factory tires.

 

looking at the P/N the OP used that does not seem to be compatible with my truck based on a quick search of online GM parts whole-sellers. I will need to research what P/N is for me.

Any recommendations on how to find a shop that knows how to properly check for drive shaft balance and true-ness? If dealer is a bust i may go that route

I heard back from the service manager and they agreed there is a driveline problem. They claim to have encountered this before and resolved it with a torque converter fluid flush.

 

I believe others have had this done, but i haven't heard of anyone saying it worked. I will report back.

Replaced tons of driveshafts for this concern. Most driveshafts I see with a problem are around 0.040-0.050 inches out. Want to see 0.020in or less of runout. I have 3 on order now

It took three weeks and one day to get my truck back. The work only took a few days buy my dealer's service dept. is just all jammed up.

 

here is what they claim to have done:

"Found vehicle to have a TCC shudder present as described in bulletin #16-NA-175. Performed pan filter replacement and triple flush as per bulletin. Programmed TCM w/newest calibrations. Performed trans adapt relearn procedure and road test to learn all shifts and verify repairs. Prog code: 18D6C"

 

after getting the truck back the vibration was gone. so for now I consider it fixed. Hopefully it does not come back.

I bought a 2015 Silverado 1500 LS Custom Double Cab in February that had a nasty shake starting around 75MPH. I had the tires balanced but it didn't help. I went to the dealer since it had CPO warranty and they wanted to try a road force balance. When I picked it up the advisor said they got the balance better but the tires just wouldn't balance properly and they recommended new tires. 

 

The tires were the OEM Goodyear Wranglers. Even after the road force I still had a shake though it wasn't as bad. I ended up getting new tires Firestone Destination LE2, and the shake seems to be gone.

    • Common Sense Assembly   Your driveline is forgiving of the occasional mistake. It will even often forgive the random serious blunder. But it will not forgive a continuous bad habit.      What? Not everything needs to be a five thousand word essay.       
    • We drove about 15 minute east today to visit a friend and saw a steep increase in price in the same county. About 50 cents a gallon steepper. 
    • Sure about that? A degree wheel and a dial indicator would lower your degree of assurance in that statement. 😉    It why we have offset keys and dialable timing sprockets. Just say'n.... I've built a few and have never seen one "On the money". 
    • I will admit I haven't experimented much with pressure drops beyond the numbers I put in and part of that is that the numbers I used are fairly low and then found out it would trigger regardless at that 35 psi. Having said that I had tried before had changed the placard pressures and being that I have a 1 ton set to 80 on the placard for the rear I believe it triggered close to 60, the front I don't recall now for sure but thought maybe it could get close to 45 from that factory 60 placard pressure. So I never did figure out if it was a number of psi from placard pressure to the alarm or a percentage of the total placard number as some figured it was like a 25% drop from placard pressure would trigger it. So as to try and answer your question, I believe I set the placard pressure on the front to 47 or so and while I run the front tires at 40, they have dipped below that some if its colder and I haven't put "winter air" in yet and never once have had the front alarm go off. I would say that the answer your looking for is no, that if you set your placard pressure to 45, you have a certain amount of room to drop below that pressure before the alarm will go off.    The pressures you decide to run in your truck, that ends up being what makes sense to you based on what your carrying in your truck or if towing, then have to bump them back up to something that will carry the load in the rear and the fronts typically left at the same pressure. It all comes down to that chart I put the link to and using an accurate roadside scale to be your guide, both unloaded and then loaded to know your minimum safe pressures.    I just wish GM would allow a person to change the readings for the tire pressures to the English system of pounds as I have to look at that goofy metric reading that will never ever jive in my head and will go over and change it just to figure out what they are if need be and then change it back. 
    • That part I understand, that the dealer can do it. But I'm not understanding why updates that were available to the truck since it left the factory, or the dealership originally, would not still be available to it without dealer intervention.   I'm thinking along the lines of recalls. They stay available until they are completed, regardless of whether they are in warranty or not, or in the hands of the original owner or not. Why not updates as well, especially since some of those can be safety related also?
