CHeck the build date. If it was built in late November through December'06, It will have the AE ratio 6 spd.
My Dec. '06 build '07 has been a great truck. I traded up from a '01. 5 2wd with the auto. The G56 is a good trans. Don't expect much extra out of the clutch if you add power. Mine held 15,000 mi with 70hp setting on a Smarty jr but now I am back to the 40hp setting because it started to slip. Southbend Double Disc 3250 is coming!
Overall, I have never regretted the '07, 5. 9 over my '01. 5
Crawl under the truck if the build date is close and look for this. Don't go by the METAL plate on the side of the trans, look for the white tape with the bar code. Look for the "AE" at the end of the number. If it reads "AD", then it is the . 79 ratio.
I DONT GET THIS, IS ONE RATIO MORE DESIRABLE, DEPENDABLE ETC THAN THE OTHER. SOMEONE PLEASE ELABORATE
