I was reading on GM's website about whats covered under the powertrain warranty. I want everyone to look at this because it appears that the covered items for 2010 are different than 2009. It shows exclusions for 2010 models on the engine and transmission. The way I interpret it is that those excluded items for 2010 are covered for a 2009 model. It doesn't show their excluded for model years prior to 2010. LMK what your take on this is. Heres the link to what I was reading.
