Guy on another site bought a '06 8.1L HD. Hasn't picked it up yet and doesn't know for sure if it has an Ally.
Did the 8.1 come standard with an Ally or was it an option?
I could swear an Ally was standard equipment behind the 8.1.

The answer is no.:D The 2500 Suburban, Yukon XL and Avalanche with the 8100 didn't get the Allison. Everything else did.

Maybe I should have been more clear. I didn't ask about the Sub the avalanche or Yukon. I asked about the HD :) Did all HD's (as in pickups) come standard with an Ally?
