Hmmmm getting nervous about pulling the trigger on a new jeep overland now. Might just wait until jeep works out the issues or how long does it usually take before the kinks are worked out? Mid '11 or should just wait for '12 or '13?
If you are going to wait for all the bugs and kinks to get worked out, you're going to have a long wait.
+1 since this isn't a new engine / trans combo. I could see if this were with the new V6 but even that is a proven trans.
These things are mechanical, **** happens. Also remember that people come to the internet to report problems. No one takes the time to say everything's great every other day but you can be damn well sure someone with a problem will post every day on multiple forums just to vent.
