What kind of bugs did they work out in the early years of the 5.3 Tahoe? Should I not buy a 00-02? I know that in 03' they coated the cylinder walls or pistons to help avoid that Chevy knock.

I heard to stay away from the 00's, but what about 01' and 02'?

Intake gasket seem to go out every 75,000 on the 5.7 and 5.3

Tranny well I know that story on these trucks.

Hadn't heard of intake gaskets going on 5.3's, only on the Gen 1E motors (305/350), and think the TBIs had that problem as well.

03+ gets you the double DIN radio, better climate control and all that. 4L60Es are better in later years as well as i understand.
