Is auto four wheel drive available with the 6 speed transmission?
I see that 2500 with the 4 speed has auto, high and low 4wd. I have not seen a 2500 w/ 6speed transmission w/ the auto select--only high and low 4wd. Is the auto select available w/ the 6speed transmission w/ the 6L vortec?
Hi desmont, I've not found any indication that the '07 or '08 Silverado 2500HD with 6-Speed transmission will have an available "auto 4wd" system. Sorry for the bad news.
