I have a 2018 Chevrolet Sliverado. As I drive I hear a rumble strip noise for only about a second then goes away. I notice this as I lightly apply the gas while driving. It sounds like its coming from the passenger side front. I have read in GM vehicles that it could be the Torque Conventer. Has anyone ever heard of this noise and what could it be? I only have 25,000 miles on it

 

You should still be under warranty. Take it to the dealer and let them fix it.

 

They say they can not duplicate the sound. Do you know what it could possibly be? Torque converter?

 

You could try another dealer and go for a test drive with them and point out the sound.

 

I had the dealership keep the vehicle overnight and had there Service Manager drive it. He did hear the noise and said it was from the transmission shifting from V4 to V6 and that it was completely normal. Does this sound right to you? Have you ever heard of this? I'm not a mechanic nor do i pretend to know anything about being one. Just looking for some answers. I truly appreciate any and all your help.

 

on my 2010 i can feel the engine cut from 8 to 4, but dont really hear it only feel a slight loss of power

 

I stand corrected, the dealership stated it is normal to hear the noise when shifting from V4 to V8. I misstated from V4 to V6. I had to turn the option "Trip A" or "Trip B" to see when it shifts and i hear the rumble strip noise. I made the noise once since i drove it home but i didn't have the Mileage Trip on. Thanks for any and all comments. This is my first Chevrolet vehicle. It is a noticeable sound that is why I had the dealership look at it. Again, Thanks

 

I disabled my my V4 - V8 modes with a tuner. I hear it sometimes when making a turn around 10-15mph or sometimes when accelerating lightly between 15-35mph... I recently changed tunes and after a 600 mile one way trip it started making the noise on the way home. But it had probably 3000 miles on it and never made noise. Does anyone think that's the same noise??
