"The best bet is 03-04 LB7". Huh???
As forcefed mentioned>>>Injector failures. It costs approximately $5500 to have this design flaw corrected. It was so bad that GM added more miles and time to the warranty.
The 01 trans was so bad,[flood gate type fluid leaks], they had an assy line type rebuild program to address the hi failure rates and lack of parts.
How do I know this?? I had 1 of them, and had these very same failures.
"Best bet"???
