A little background just bought this truck 2 months ago, last week I went camping with a friend in the bed of the truck. After 2 days, I pulled the truck out of the parking spot in reverse and there was an extremely loud grinding and very loud clunking from the rear end. The noise was so loud people in a cabin 20 yards away came outside because they thought I had hit something. Check engine light came on, pulled code P25A2 and U0146. Now whenever I use the brake in reverse, there is a loud grinding sound from the rear drivers side wheel. The truck did not make this sound before these codes showed up. It's usually louder in the morning/when it's cold. I've had it at 2 dealerships who say they can't reproduce the noise (by the time they get around to examining the vehicle it has quieted significantly) But the next morning when I back out of my driveway the loud grinding and squealing has returned.

Hello everyone, Well I took my 2014 Chevy Silverado 1500 up to the dealership yesterday for transmission issues. When accelerating around 30mph the transmission makes a high whining noise around 2000 rpm almost like its slipping and the truck shakes back and forth. Then when on the interstate on cruise control around 65-70 you will hear a grinding noise every few minutes. Also when you slow down from the 60-70 mph range to around 30 mph and accelerate the grinding noise becomes more apparent. When I dropped the truck off yesterday I showed the service guy video of the grinding as well as what I believe to be slipping and he said "Yeah that sounds like it is slipping". Received a phone call this morning from the same service technician saying they were not able to replicate the issue. That the transmission guy said that is normal when it switched between V4 and V8 mode. It's amazing I have had this truck and driven it for 76000 plus miles and have never heard that whining or grind noise. I asked how long they test drove it and he said 10 minutes. I told him they need to drive it around longer and actually go on the interstate to hear and see what it is doing. This is not the first time I've taken my truck up there for transmission problems and I am not picking this truck up again until they find the issue. The first time was for rough shifting to which they said was normal. This is my first Chevy I ever have bought or owned. Bought it brand new from the dealer. I must say that with how I keep getting treated with the "can not replicate" issue as a scapegoat for not truly trying to satisfy the customer is getting old. Especially being I have videos in which you can see the rpms and hear the whine up and hear a grind noise. This will most likely be the last Chevy product I purchase. If anyone has any ideas and doesn't mind listening to the videos I have I would appreciate it. I will have to post a link to youtube since the video will be to big to post here. Thanks

Getting some pretty nasty sounds from my transmission and wondering exactly what it may be. It seems to only make this sound when in Park or Neutral and also when the truck warms up, does not make this sound during start up when cold. Truck has about 152,300 miles and i had replaced all the fluid, filter and two solenoids at 148,600 miles 7 months ago. I'm pretty much expecting the worst here, but if anyone could give me some more insight as to whats going on besides it probably dying, i'd appreciate it.

I'm trying to buy a 2004 Silverado 1500hd with the 6.0 and 4l80e. When test driving the transmission would shift through all the gears fine but if you let off the gas as soon as the rpms hit 2000 they would drop to 1500 to 1000 and there would be a loud grind/whine until you tapped the gas again. I'm assuming it's the transmission, maybe the torque converter. Any help would be great so I can figure out if the transmission would have to be rebuilt or if it's something simpler to fix

Hi, I’ve got a Silverado 2016 Z71 4x4 with the 5.3L. When I take my truck to work in the morning (cold start) and make a left out of my neighborhood, my truck makes a grinding noise as I accelerate during the left turn. It sounds like metal cans clanking. I can feel it in the gas pedal too. I’ve tried reproducing in an empty lot by turning and accelerating and I get nothing. It was really bad one time when I made a right turn out of a parking lot onto a Main Street. The street was lower than the asphalt I was coming off from and so my truck bounced a bit while I accelerated right this time. Grinded really bad. Any ideas?
