General Motors Complaint - transmission knock, and unknown noise
VIRGINIA -- i have a 2003 chevy silverado ext. cab 4wd 5.3 litre engine and 4 speed transmission. i have less than 5000 miles on it and the transmission is making a knocking noise every time it changes from 2nd to 3rd gear on th upshift and downshift. it has been doing this almost ever since i purchased it and its progressively getting worse. sometimes it does it on the 1st to 2nd gear change now. i was told by chevrolet rep. that this is a characteristic of truck and nothing to worry about. that is a totally unacceptable excuse. i also have a noise that occurs when driving around 40 miles per hour that no one can explain, it sounds like some kind of vibration. this is my first general motors product and probably my last. no wonder people are buying foreign cars. with quality like this i don't blame them.
