This is my first auto transmission car in years, so its quite possible thats why I'm noticing this .... but the trans seems to shift hard/rough when going straight from Drive to Park, or Drive to Reverse. Park to Drive or Park to Reverse is clean/smooth.
I too noticed this immediately when I took delivery. It a byproduct of the way the torque converter operates. This is not exclusive to this package, others do it as well but the V8 / 545 engine/trans package seems to be worse than others. What's happening is the torque converter isn't fully disengaged when the vehicle is in gear so the drive train binds up against the brakes. When you take it out of gear it release that binding and you get a clunk or "bang". It gets better over time as the torque converter wears in. It's also noticeable when you are stopped in gear. With some automatics you can release the brake and the vehicle won't start moving forward until you give it some gas. On the WK2 it starts moving immediately hence the drive train bind.

Not many vehicles do that. The expectation among American drivers is that the car will creep forward when the transmission is in D even with no commanded acceleration. My wife's Prius mimics that behavior -- it will engage the electric motor to creep forward.
I don't know if it would be the same thing (I have a WK) but you might want to check your diff. bushings. I had the exact same issue with mine, it was a hard "thunk" when I shifted from P to R, R to N, R to P etc. Ever since I replaced them it shifts smooth as can be. Don't know why they would be bad on a brand new vehicle though?
yeah im having the same problem here, when shifting from D to N, R or P the thud is so obvious that it feels something is not quite right in the gears...is this something that can be solved or is it just the way it will always have to be???
Noticed the same problem right after taking delivery. Interestingly enough it's not all the time but most of it. Was thinking of convertor- felt similar hard engagement on rebuilt transmissions before. Technically should've taken it to a dealer but forsee "they all do it, more or less" response. Will keep watching it for now- it does shift nicely.
Yea my 2011 jeep grand cherokee does the same thing. The dealership says that the transmission shift hard due to the drivers driving habits.
DON'T MAKE SENSE TO ME EITHER!!!!
Mine has the same problem. 5.7 overland..just got it today and noticed it right away ! The dealer said that it's normal on 5.7 engines and it won't cause any issues..so no worries.
Same what about when u are driving in reverse backing up into a spot in my garage with dead silence I noticed this strange sound while driving slow in R then cluck to P
I THINK I remember seeing an update for a harsh engagement into drive just like 2 weeks ago when I had a wk2 hooked up to the witech. Ill look around and try to find some more info.
My 05's been doing it for years. Seems to like when I take my time putting it in gear. If you look hard enough, you'll find posts on this subject on 99-04 jeeps...
My 2012 Overland WK2 is only two weeks old and it does it too. I did not notice it during the test drive, or during the first few days. However, it does 90% of the time now.
I feel like I'm driving a clunker as it makes a very loud CLUNK when I shift into park.
I have had many automatics in my life, all bought new (two Nissan Maximas, one Honda Civic, one Ford Mustang, one Mazda MPV, one Toyota Highlander, and one Toyota Sienna), and this is the first where I have seen this problem.
I've found that bringing the vehicle to a complete stop, and letting it idle for 15ish seconds makes a ton of difference. If you shift from D to P even the slightest bit abruptly causes this clunk.
I playedcwith this yesterday and noticed that if I go to P very fast ther is no clunk. If I go to P smoothly and slowly it clunks loudly. Seem to be more when I hit N then when it hits P so perhaps by going fast to P it never really has time to thump at N!
