Bad vibration at highway speeds
Brianibew replied to Will Baribault's topic in 2014-2018 Silverado & Sierra Troubleshooting
Sounds like a torque converter issue, unfortunately. -
DEF Tank - Frozen

There is a heater in the def tank. It may have failed. -
2022 1500 Wheel Shake and Vibration, and Towing Issue
Brianibew replied to MrLeadFoot's topic in 2019-2025 Silverado & Sierra
Just my opinion, but look at the large sidewall of the tires on your Suburban and compare them to the tiny sidewall on your new Denali. The sidewall plays a huge role in soaking up those road surface inequalities. I don’t really understand why anyone would want over an 18” rim on a truck, and that is pushing the comfort limit at 18”…but I know, the larger wheels “look better”…for some reason. -
Hesitation when accelerating
Brianibew replied to Harv3589's topic in 6.6L Gas V8 & HD Transmission Powertrain (L8T/MYD)
I would guess if it’s not enough demand to issue a downshift, the shudder you’re feeling is the torque converter. Lots to read on GMs torque converters. -

Duramax not starting
Brianibew replied to Flyingwhiskey's topic in 2015-2019 Silverado HD & Sierra HD
Take a video of it next time it won’t start. Call the dealer and request a tow. Show the dealer the video. Tell them you will pick it up when it is fixed. Contact GM and open up a case on the issue. -
I’m not sure about the 6.0, but when I did my 5.3 it had a screen under the oil pressure sending unit. Make sure you check to see if it has one or not because if it’s plugged up, that could be causing your low readings. Most sensors completely fail when they go bad with either high readings, or no readings...which kind of makes me think it’s either a plugged up screen, or an actual mechanical issue happening.

failed lifters 2015 6.2 - JUNK motor

I’ve had both 1/2 and 3/4 ton Chevys and I will say I prefer the C channel frame of the Tundra in terms of ride quality. It absorbs poor road conditions much better in my opinion. I agree about the outdated tech also, but on the other hand, it’s tried and true proven tech that has been incrementally improved upon over and over instead of changing the entire design every 3 years like most other manufacturers are doing and sacrificing long term reliability in the process.
