Around 15K I had the transmission issue with it slipping and the dealership replaced the fluid with the mobile 1 which seem to resolve it enough that i could live with. The transmissions still clunks into first when down shifting but whatever. Well now at 30K I have something similar going on, but seems just slightly different. When I'm cruising around 35-40 it almost feels like the truck is braking or downshifting and then speeding up, but enough everyone in the truck can feel it. At first i was thinking it was the DFM kicking in and its opening and closing valves so i bought a pulsar box ( i needed it for tires and autostop/start as well) and disabled the dfm, but it still does this weird shimmy. I know that doesnt necessarily still mean its not dfm but... still.
This may sound crazy, but its much worse when its really hot outside and the truck has been sitting for bit. This morning it was cloudy and about 80 degrees. Didn't notice it too bad when i left, but this afternoon it was about 95 (truck had been sitting in the sun for several hours) and when i went to leave even the passenger was thinking i was about to run out of gas once we leveled out around 40. After stopping and going a few times it settles down enough that its back to just being very subtle, but still noticeable.
Is anyone else experiencing something similar? Is it DFM, Torque converter, transmission or just something i will have to trade out to resolve.
I appreciate any answers that are offered up because i really, really don't want to get rid of this truck.
Welcome to my build!
Started with a 2019 Silverado 1500 LTZ 4wd 5.3L, which I bought with 9k miles on her in August of 2020. Got a crazy good deal on it, justified me driving to Georgia from Houston to pick it up. It even came with the Ranch Hand front bumper on it already, other than that she was stock.
Little bit of background on my past trucks, I've been fortunate to own quite a few: 07 JK Wrangler, 08 Silverado 1500 LT Z71, 2014 GMC Sierra 1500 SLT Z71, 2015 GMC Sierra 1500 SLT w/ 6.2L, 2016 Denali 2500 Duramax, 2017 Silverado 1500 LTZ Z71, and finally my 2019 Silverado 1500 LTZ Z71. I also have my 2015 ZL1 Camaro for a little bit of fun on the side, my wife has gone off to German side and is rocking her Porsche Cayenne.
So here's the current list of mods:
4" Zone Lift kit w/ Fox rear shocks 35x11.50's Nitto Terra Grapplers on stock 20's Front and back Ranch Hand bumpers Hooker Blackheart Cat-back exhaust utilizing factory dual tips K&N Series 63 cold air intake Rough Country Automatic drop down steps Camlocker Tool box Front windows tinted to match back factory tint Front windshield tint strip Chevy All-Weather floor liners Stubby antenna
Just went on a shopping spree of sorts and this is what I've got on order:
Boost auto parts auto fog mod Putco Blade LED Tailgate Light Bar w/ Putco wiring harness All LED bulbs; replacing turn signals, license plate lights, and reverse lights. And the GRAND finale, King 2.5 PRS coilovers
The list of things to come in the near future:
High Country cluster from White Audio and Media, had their Tahoe cluster in my 2017 and it was fantastic! Waiting to order the rear King Resi PRS shocks until my checkbook bounces back a little bit. Lol Going to be putting on several LED light bars and maybe a pod or two, going to do my best to blend them into the Ranch Hands and make them as non conspicuous as possible. I'm strongly considering doing a Dyno tune w/ Kooks long tubes as well. Going to be doing ceramic tint all the way around. Limo on back windows and back glass, 15% on front windows, and 35% on the front windshield. I've got a drop in plastic bed liner that drives me crazy, so I'll more than likely go ahead and get the bed sprayed.
Things I'm considering:
Looking into changing up the rims and trying to clear 37's when the time comes for new tires. Blacking out the badges? Still not sold on this one... Turbo or a supercharger kit? This one would be way down the line though. Anything else that catches my attention, let me know if you can come up with anything!
Here is the truck from stock:
Hi all, new to the forum, but have been reading random threads. I own a 2020 Trailboss, and my wife has a 2019 Suburban Premiere 6.2.
I did some searching and couldn't really pinpoint any good discussions on this.
I'm looking to add exhaust to the Suburban. I was hoping to accomplish 2 things:
1. Marginal increase in volume/sound, she wants people to know she's on the road
2. "Dual" exhaust, however I can't seem to find any good pictures or systems that exist out there. Honestly I don't even want/need the tips visible, it would be great to add a 2nd exit on the driver side, similar to what's currently on the passenger side.
Anyone do/see anything like this or know of a system that exists?
2019 Silverado WT has the power tailgate. It’s stuck on one side. The passenger side latch comes undone but the driver side does not. Any ideas on how to get it open? Can’t find anything jammed and the tailgate is on properly. Not sure how I’m going to get it open.
I own a 2019 next gen sierra (elevation) and I'd like to install the extended view tow mirrors (part # 84776098). My truck is equipped with DLF and not UKC as specified in the part description. GM says these mirrors will not work on my truck …. GM enthusiasts. Is this true? I feel like it's bullshit and the harnesses are plug and play? If they're not plug and play, is there an alternate harness? It can't be possible that this 1/2yr model can't be equipped with tow mirrors? Help please …..
