Low rpm rumble

Jjk537 · February 16

2024 Sierra Elevation 5.3 10 speed.

Does anyone else notice a rumble from the transmission when traveling at a steady speed usually low 40’s with the rpm’s around 1200.

actually vibrates my dash sometimes. The dealership say its a characteristic of the 10 speed but it sucks, period.

started around 7k miles and is getting worse.
I can avoid it by putting the transmission in low and limiting to 9 speed.

anyone else frustrated by this?

Sounds like it’s AFM/DFM kicking in. Shouldn’t be that noticeable though. Some trucks are worse than others. I’ve had a bunch of GM trucks with AFM. My 2019 Canyon with the 3.6L is absolutely seamless, I can’t ever tell when it’s engaged. I had a 2014 Sierra 5.3 that was noticeable, but not annoying. I also drove a 2016 Silverado WT that was noticeable as well, a little more annoying. I tuned it out on that truck. My 2022 Silverado 2.7 is a vibrator tho. It’s noticeable and annoying.

Options are: to live with it, tune it out, limit the trans to L9, or move on.

Sorry for you’re troubles.

Yes I am frustrated by this. I also leave mine in L9. I hate DFM. Still waiting for Range Technologies to start selling a DFM delete. My last Trail Boss 2021 was built without DFM because of the chip shortage.

Thank you for the response but one thing I neglected to mention, this truck does not have any energy management do to the chip shortage.

I’ve been researching this topic recently as i have a low throttle shudder that becomes almost a stutter in low gear shifts. Most posts report dealers replacing torque converters, transmissions and injectors. I’ve read mixed opinions about all them. Currently my 5.3L 10speed is at dealer awaiting torque converter.

What year and model is your truck?

I think I may be starting to feel a stutter in my transmission at 3000 miles. 5.3L 10 speed. Please keep us updated on your situation.

Not just 10 speed. I have a 8 spd 2.7 turbo and between 1k and 1500k rpms if I get on the throttle slowly my dash rumbles/rattles whatever you wanna call it obnoxiously. Has anyone actually found the rattle point or a fix or a dealer that actually looks into the issue?

Jjk537 · February 21

What I should have mentioned when I started this post is my truck 2023 Elevation 5.3 with the 10 speed transmission has no energy management active due to the chip shortage when purchased in 2022.

when cruising between about 38 and 44 mph and just feathering the throttle it begins a low rumble and it’s pretty annoying especially when the dealer tells me it’s nothing.

i have a new truck that vibrates and it’s nothing haha.

wondering if there is a way to contact GM directly.

someone is hiding something

That sounds like a TC lock-up issue.

Dealer told me the TC had more slippage then specd and replaced the TC. It did nothing, as I still have the rumble and even hesitation while shifting gears at low throttle.
