Searched a bit and found others who had similar issues but didn't seen any real resolution except for some general advice that has worked on other platforms.
Had a 2010 JK, supercharged, on the dyno and with it in 2wd it was throwing a fit and only allowing autostick in 1st gear, no response to hitting the shifter trying to move up gears.
What have you guys done to get these things into higher gears?
