  1. I have gone through 3 transmissions and 2 torque converters and I still have the shudder problem and this is just on my 2015 Silverado Z-71 6.2 with 182,342 miles. The dealer is kind enough to replace under warranty. I also have a 2018 Silverado Z-71 6.2 8spd that has the same shudder. Fluid has been changed and next step is torque converter.
  2. I have a 2008 Silverado Max 6.0 Z-71 4 x 4 with a 4L70E transmission and I can positively tell you that your second gear has gone as my truck is at a local Chevrolet Dealership in Kenner, La waiting for the replacement transmission to come in. My truck has 489,674 miles on it and the current transmission has 212,028 miles.
  3. UPDATE, After several nagging trips back and forth to the dealer, I finally have the answer. They are going to replace the entire rear end assembly due to all of the previous work. Stand by for updates
  4. I have a 2015 Silverado Z-71 Crew Cab 4X4 and the paint is flaking off of the rear drivers side door and bed. From all of the post's, GM needs to correct problem for us.
  5. I have owned 29 Silverado's in the last 30 years and had 2 lemons in the bunch with the 2015 being one of them. I currently have a 2008 Silverado Z-71 working on 600,000 miles and going strong. My 2018 seems to be ok as it too new judge. I bought it leftover dealer stock at a steal, I hope that you get your problem resolved as well
  6. There is no humming noise that I can hear. All bearings were replaced when the rear end was rebuilt again 4000 miles ago. One other thing forgot to mention, the dealer put my spare on the right rear and test drove the truck and he said that it made the vibration in that speed range 10 x worse. I expect that to be the size difference of spare tire and it may be out of balance.
  7. I may let the dealer swap axles at this rate just to see. If that is the problem, they can replace them under warranty. They should just replace the entire rear end assembly with as much work that has been done to it.
  8. I let the dealer use the driveshaft from the 2015 Silverado and put it in my 2018 Silverado and no vibration. That rules out the driveshaft. In fact, I just had them leave the 2015 driveshaft in the 2018 as I was in a hurry. Supposedly the dealer was getting a tool to test my axles.
  9. I have a 2015 Silverado Z-71 6.2 4X4 that was towed from the rear after the fuel pump died. When I picked the truck up from the dealer and hit the interstate, I accelerated to 70 and when I hit 71 the truck felt like it was going to come apart until I reached 80. Returned to the dealer and after 2 months, the truck is still on the rack. For full disclosure, the rear end has been rebuilt twice and the cause for those rebuilds were from me pulling too much weight and a bad rebuild at the dealer. Any ideas?
