I've had manuals for years and as I got older just got tired of the constant shifting in traffic
my 2010 is an auto but as mentioned, the 3 speed (IMO it's a 3 speed with a ridiculous gear jump to OD rendering it useless as a 4th gear) with the 3.8 is not the best combination. It gets the job done on the trail but it does make driving a chore on long freeway trips . I've never been as tired as I have driving this Jeep after long trips, it's a chore! but the fun it provides is worth it.
the 2015 with its 5 speed/ tap shift is much easier to drive, smooth through the gears and when you want to stay in a gear, tap..no clutch, no riding the clutch, it's a nice drive. The added power is noticeable, but the smoothness of the transmission is night and day.
I don't plan to get rid of my 2010, it'll likely get an LS swap along with the tap shift automatic transmission but if a diesel actually comes out in 2016 well then...... :thinking:
