fla 9 Posted October 13, 2009 you could do, but the later autos did not have it, the TCM was adaptive and gearchange was controlled by how you drove it. Mapping was the same, but with it in S, it would hold 3rd gear for longer. The problem is that with this being a hydraulic change you would lose power in the drivetrain. The earlier had a hydraulic & mechanical shift between 2nd and third. Quote Share this post Link to post Share on other sites
