Loud squeal noise in the transmission of 2006 chevy silverado when it runs in low gear and when it is in drive and shifts from low to high gear. The truck was taken back to the dealer 2 times and we were told it was a normal noise for the 4l80e transmission. We took it to another gm dealer who said there was a problem. We called gm and they had us take the truck back to the dealer we bought it from. We were told it was a normal noise after the mechanic drove it. When it was used to pull a trailer loaded with hay, the noise was even greater. I am concerned that there will be an accident with this truck.
