I talked to a source of who was looking through GM service training info at my request through the dealer system. He told me that it shows an 8L90 8-speed auto Transmission listed on the internal RPO(regular production options) list for 2015 yukon Escalade and suburbans. I thought this was very interesting and wanted to know what you thought about it. Heard anything else? To me this only confirms that the Denali will be offered with an eight speed transmission and at a minimum by the 2016 model year and possibly midway through the 2015 model year.
