I hope Im just missing something here, but I was on GMC's website and they arent mentioning the Allison tranny, just a Hydra-Matic 6L90 six speed. Whats up?

Allison is not available on 1500's, never has been. It is available on the 2500HD with the Duramax or the 8.1L (Think the 8.1L is no longer an option)

I know, I just wasnt seeing anything about the Allison when I was looking at the HD's.

I think I may have answered my own question. This articel was saying the new tranny is for the gas burners. I may have jumped the gun I think.

According to the website in your first post and by clicking on the 2500 or 3500 tab it doesn't mention Allison, it says hydramatic!!
