My dad has a 2006 Chevy Silverado, 2WD, with the 4.3 V6.

1)What transmission does it use, it's the automatic.

2)What Axle ratio would it have(it has the towing package)

3)where can I find some "nerf bars"(tubular side steps)? It's an extended cab with the 6.5" bed.

Quoted: 2WD "nerf bars"(tubular side steps)

On GM cars and trucks, there is a white rectangular sticker somewhere in the vehicle with production codes.  On the 91 pick up I owned, it was in the glove box.  The codes start with a letter and have a couple numbers.  All of these codes represent different options.  For example, the transmission for your truck wil have a M30 or an MT1 transmission.  The M30 is a 4L60-E transmission and the MT1 is a 4L80-E transmission.  If it was a manual 5 speed trans, you would see the code  M74.  GM has a boolet that list all the codes for their vehicles and what the codes mean.  You can get a book by calling GM.

Another way to get the information (and much easier) you want is to take the VIN to a dealer or call them, and the parts department can look up your specific truck and tell you everything you need to know.

I can't answer the nerf bar question, but if you go to a Chevy dealer see if they have an accessory catalog for your truck.

Thanks Mike I'll have to look that up.  My dad got a postcard from GM Accessories, with a coupon. The GM accessory nerf bars AREN'T cheap.  But thanks.

I'm sure someone sells them in the aftermarket for a cheaper price, but I don't know where to look, so all you can do is some searches for truck  accessory sites.

I think maybe I'll check into Autozone or Murray's Auto. Thanks anyway Mike.

Quoted: The M30 is a 4L60-E transmission and the MT1 is a 4L80-E transmission.

Most likely it's a 4L60E. The -80E's only came in HD vehicles (3/4 and 1 ton).

Right.  I think my dad's '97 came with a 4L80.
