DEXRONŽ VI compatible
Until the mid-2006 model year, all six-speeds will be produced filled with DEXRON III fluid, although the transmission has been validated for used with new DEXRONŽ VI. In mid-2006, the six-speeds will come filled with DEXRONŽ VI, which was developed to behave more consistently during temperature and other environmental variations, as well as to provide even lubrication of the moving surfaces of the transmission.

Yep. Also means all the III laying around on shelves should get a little cheaper. Im just curious what happened to IV and V. Did i miss theyre release or were they utter failures that gm never released.

IV and V have been around for a while now.
