You could rightly accuse me of being an old fuss-budget, but I find the six-speed in my 2014 Unlimited to be seriously clunky (like an old, non-synchro truck from 40 years ago). I know it's not designed as a smooth-shifting sports car, but grinding from 1-2, 5-6, and into reverse seems over the top. Is this a synchronizer problem, or a shifter problem? Does anyone have any successful experience with overhauling a perfectly functional transmission, merely to improve shifting? Or is there a well-known shifter kit I've overlooked that would significantly improve things?
