My 2006 silverauto with the durmax engine and alison transmission. The transmission line have been leaking. I have 60,000 miles on it so the warranty is out. When I took it into the Chevrolet dealership where I purchased the vehicle they would not cover the leaks as part of the drive line warranty. When I purchased the lines from the parts department they indicated that they were selling a lot of these hoses due to leaks. If there are this many lines leaking I think Chevrolet should replace these faulty lines at there expense. Also I know of one other 2007 model that burned out the transmission due to these lines. Because the transmission failed Chevrolet replaced the transmission and the lines.
I had a transmission cooler line to fail and leak badly after 41,000 miles. It was caught in time to prevent transmission failure but how about the next one?it was replaced with a new part at the chevy dealer.
