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.

This confirms something for me, my suspicion has been that these truck resonate at 39 Hz which means even slight disturbances can cause vibration issues. Which for tire speed peaks at about 75 mph.

Hey guys,   I posted in the giant thread about my fix but I'm sure it's already gotten lost. I think this is important to at least have floating somewhere for someone to search.   Symptoms: At 6

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.

      My expectations are a bit higher.    No faded paint or dry rotted plastic/rubber. I use a dressing and a ceramic sealant. No hazy headlights.  No door dings. Small dent in the front bumper. All rock chips repaired. No brush scratches. No windshield chips. No fender benders. Limit damage due to a proactive plan the included ceramics and PPF and prompt attention to any exterior issue. NO RUST. Stays out of the salt and had the rear wheel wells Line-X coated as well as the bed which has a bed rubber and has been under cover since before I bought it. Washed and detailed regularly. Rex chewed up the tow button, got whacked and the button replaced the same week. He's leaned his lesson. If I can train a dog the kids are easier.    All suspension is original save the King Shocks I installed very early on. 50 years ago dad told me a good shock will keep the screws in the dash tight and the front end mint. He was right. Everything within new spec yet, tight and aligned well several times. Coolant system is OEM save the modifications I made early on. Not a single leak anywhere on this machine. (Did repair an intake leak on #4 during the HPFP replacement.) The injectors I replaced didn't need to be. They checked out great. One of those, while I'm in there with the manifold off and the fuel rail apart things.  Not a stain or abrasion one to the upholstery. Have kept is covered since new. Never had a carpet, it's a work truck but the carpet squared I laid on the floor have keep the factory rubber liner MINT. Ceramic wind tint helps preserve the interior.    Original BRAKES with 60%+ left of the pads and rotors mic excellent. We just did a full preventative brake service. Disassembly, clean inspect including measurements, lube, Dot 4 power flush including ABS system.    OEM battery. OEM vacuum pump. In fact the only things not OEM are a pinion seal the high side pump and injectors and a small plastic shield around the starter. All hoses/belts etc.. are still in service and doing well. Original tires lasted 125K and had I known some additional details would have made it to 150K with legal tread. (Date out is six years, not 5 and Continental says they are good for 10 so I pulled the trigger to early)   I never let my children or grandchildren run the show. Feet on the floor and hands in your lap. Dog gets a pass.    A truck is a machine the gives you back whatever your willing to put into it. Same as a computer or a butter knife. I use a shovel but I scrap it, hose it off and oil it when I'm done with it. My original spade I've had 60 years.      Set the bar higher...you spend less money. No, before you ask, I have spent a fraction of the cost of a new truck in my entire maintenance program including disposables, filters/fluids etc.

      5.48 regular still here at Kroger. Stations here aren't getting the memo but the owners are probably tired of programming prices up/down with every headline and futures gyration.   WTI Crude is over 80 again but seems mostly unfazed after the exchange of fire in the Middle East over the weekend and ceasefires falling apart. 🤦‍♂️ Enough already...

      Looking at ordering a '26 WT because I want a std cab, std bed

      Keep an eye on it with them.  Did they give you an order #?  Did they actually have allocation for one?   I double checked the dates for 2026 regular cab 1500s for Chevy and GMC, the last dealer order submission date was April 30th.

      5 miles away at Marathon regular E-10 87 16 $4.87 😱 25 miles away at Shell V Power Nitro+ 93 for $4.89.    In general not hard to find regular for $3.99. Seems everyone isn't getting the same memo. 😏
