I have a 2004 Silverado 1500 and I had heard about a TSB for a pin that engages the clutch on the automatic transmission for the lsd rear end. Without previous issues or warning my rear end in my silverado went out 2 days ago while I was leaving from a stop at a red light. The car was rendered immobile and I had to have it towed to my local shop in which for everything to be replaced is going to cost ~$2000. This TSB can save me thousands but since there is no official recall, gm will do nothing about it. I know judging from the truck forums that there are numerous owners with this same issue. Please help gm make this right for us loyal gm customers.
Clunking sounds from transmission/drivetrain. Generally louder when shifting into 2nd gear. Have mentioned to dealer a couple of times and was told it is normal. This is a widely known issue on the web.
