Old platform same with the engine. They haven’t really changed it since 2007. I had a GMC Sierra Denali 2016 with the 8 speed so I feel your pain. It was terrible to drive. I am replacing it with either a Ford or a Ram. I have test driven booth. The Ram interior was amazing. It is probably the best/most luxurious truck I have driven. The Titan I felt was already behind in technology and the interior felt cheap.
