Most of the people that drive them seem to disagree with you. Enjoy your opinion.

If you like it that's great and there is nothing wrong with that. I just don't see why someone with a nice JKU or JK pre 12 trade up for the same thing minus the drivetrain change. Yea it might win 0-60 but, other than that its really not all that different. It can rev a little higher than the 3.8L being its overhead cam design but, that's the only major difference besides more power at really high rpm. I can understand someone buying a newer one that don't have a JK or JKU already but, wouldn't trade a perfectly fine older JK just to have the 3.6L and w580 especially money wise what you would lose to get into a new one. If it had a small little V8 like the 4.7L then it might be worth it.

Mine is still good with 17,000 miles on it, My only beef is you have to get the rpm up above 2000 or it literally falls on its face, Mine is a standard transmission, I test drove a automatic and it didn't have this problem

It has more power *everywhere* including just off idle due to the variable cam timing and better engine tuning (including ignition and FI tuning to go with the cam), and gets better gas mileage too if you hold off the skinny pedal (not a *lot* better, but better). That said, I agree that the 3.8L -> 3.6L by itself is not a reason to buy a new Wrangler if you already own one with the 3.8L. Unless maybe it's the 3.8L mated to the 4 speed automatic. Now *that* was a true dog .

Yea I noticed that on my buddies 13 Rubicon even with the auto. I like the w580 its a very good transmission. I even like the 42rle that I have. I think the biggest problem with it was it was never made for the 4.0L to much transmission for that engine. Even my old LJ with 4.56s sometimes would hunt all over the place trying to find a gear. I don't have that problem at all in my 08 JKU even with 3.73s and I get better gas mileage doing it vs the 4.0L I average about 18 in my JKU with mixed driving. Highway 19 all day long. My LJ would struggle to get 14 on a good day and was lighter than my JKU. Running the same size tire 32inches I don't see the need to re gear my Jeep just yet especially the gas mileage I'm getting. I know the 3.6L in any tranny would smoke the 3.8L 0-60 but, other than that its the same as the 3.8L with the exception that the 3.8L has a little better power on the lower end.

Unless you put 35s and run stock gears its fine. I have no problems with my 42rle. The 42RLE behind the 4.0L is a true turd even with the right gears.

35's and stock 4.10 Rubicon gears with the A580 and 3.6L works fine.

I always pull people out for free, but that's just me. I guess if you want to troll the beaches to gain from someone's stuck that's your right.

+1 on the free pull/tow by me on the St Augustine beaches. Amazing tho to see the vulture trucks awaiting their minivan prey. One time I offered to help a foreigner with a bottomed out vehicle in the sand - he refused my offer... thinking I was going to try to scam him. I eventually pulled him out and wished him a nice day - somewhat to his surprise.
