So, from all that I can find, do all the 2010 extended cab Z71 4x4's with the 5.3 have a 6 speed? I'm looking at one this weekend from the internet and it says it has a 4 speed on the site but I thought all the 2010's with the 5.3 had the 6 speed?

Here's the front end of the Vin

Plus its at a Ford dealer so they may or may not know the details...

 

Nope, not in a 5.3 - 6 speed is only option....here is the manual

darn

 

its true they only come with the 4 speed and 6 speed is an option. I have a 02 1500 Z71 its not to bad with the 4 speed. If i keep my foot out of the gas with the mods on the truck i can get an easy 17 mpg the most I have ever got was 19.6 mpg on the hwy that was going down hill most of the way for 100 miles with the wind at my back lol. If you need any help at all with your truck this is a great site. Everyone tries to help everyone on here. I for one have to say this site is amazing its helped me out alot. Have a good one...

 

Its got a 6 speed.

SCORE!

Got 21 MPG on the way home

 

That's not surprising with the flex fuel. Glad to hear you can now rest easy!

 

So... how noisy are the Dueler A/T's? I get a really distinct tire noise from the front around 40mph. I just wanna be sure that I don't have front end problems. Tires has 24k miles on them.
