P1000 Transmission Rattle

[russknight]

My 2016 1000-3 has a "rattle" in the higher gears when driving slow under load. It seems to be more noticeable when in manual mode in 5th and 6th gears on pavement just lugging along. When I accelerate and rpm's come up, the rattle goes away as the normal transmission whine becomes prominent. Anyone else notice a sound like that? A passenger asked recently if the valves were rattling.

I just bought a 2019 in November and the tranny does seem to be fairly noisy. I’ve noticed the rattle sound you described but it seems to be normal.

Yeah, it's normal. It's the slack in the front drive shaft when it's not engaged. When you run it 4WD, you'll notice the rattle goes away.

I'm not sure that is the issue. Sounds like it's coming from the rear section of the engine. Hard to tell.

Sound like this?

Mine turned out to be front driveshaft. Only noticed on pavement above around 30mph and under load (accelerating or going uphill)

Doesn't sound like that.

mine started doing it around the 650 mile mark.took it into the shop and was told not to worry about it? at least it's documented if it fails later.mine almost sounds like the exhaust is rattling,but it still pulls fine under acceleration.i run mine like i stole it so if it is going to fail it'll happen soon.

Mine makes the exact same noise and I've posted on the forum asking about it and got no answers. Did you replace the front driveshaft or is it something not to worry about? I had my skid plates off and wiggled the drive shaft and it seemed to have more play than I thought it should have and figured that's where the rattle was coming from.

That's what mine sounds like too.

Does it sound a little like marbles rattling around the heat shields? Cause I've noticed something similar too

Yes mine resembles the noise you described. I just don't know if its a big deal and needs to be brought to the dealer while it's under warranty.

I started to notice it not long ago. It only has about 200 miles on it too. I might bring it in one of these days just in case. Like @rickoshea said, if they say it's fine and it fails later on, it'll b on record.

Could be muffler heat shield too.

I took it to the dealer and they replaced it under warranty. They had the same thoughts that it had more play then it should have.

 

[0860silverado]

Doesn't sound like that.

Yeah, that is definitely a different sound than what a front shaft makes. I'd say a heat shield. Maybe remove them one by one until the noise goes away and then address and re-install. (Definitely re-install!!!)

Just looking through the forum and saw this thread. Could what you are hearing be engine ping? High load situations is a good recipe for pinging and can sometimes sound like marbles in a tin can.

I have the same rattling noise and it's driving me bonkers. Have a listen to the video to see if you might have more ideas to help identify the noise.
If you watch the suspension move with the noise, it feels like it's in the suspension.

Did you ever get any answers on this? My 2021 with 200 miles does exactly what you’re describing. Sounds like marbles in the rear when in a higher gear below 3k rpm

Nope, no idea. It's still doing it. It might be the infamous chain tensioner.
