Sorry I know its a dumb ass questions i'm new here and to chevrolet's.
The truck I'm looking at is an 05 four door with the duramax. I havent test drove it yet. Also do the 05 come with the manual mode like the 06?

If the truck has a Duramax and an automatic transmission, it is an Allison 1000. Unfortunately, the 6 speed version of the Allison (with manual mode) did not become available until the 2006 model year.
