thank you !.. yeah i got the 2011 but i thought there was no difference between 2007 to 2011. also i driven on the beach on the sand on 4 wd high and never had a problem (not even lower the air lol)

X200 million! That goes for ALL 4X4's no matter what. Why burn up the trans when the gear ratio is right there for you two positions away from 4-hI

Airing down makes a huge difference on beach/sand riding. I can drive on the beach around here in 2wd when Im aired down.

I know this is an old post, but for the sake of those doing a search, here goes. I learned most of this less than a month after my used purchase and 15-20 minutes after hitting the beach. I have an 09 JKU automatic, so some of this wont apply to manuals. After much research it seems the general consensus is to air down to 15-20 psi as a starting point. I would say the posts above agree with that. Use 4L. '07-'11 auto's will overheat in 4H unless travelling 25-30 mph. Related to that, get an auxillary transmission cooler. The stock cooler is mounted to the a/c condenser and is tucked behind a cross-member and the front bumper. It is undersized and gets almost zero airflow. You can also turn your a/c on to force the cooling fan to come on. I believe 4L automatically turns ESP off, so that's covered. Also, turn O/D off. More than a little late to help the original question, but hopefully useful info to others. You can find more related info by searching this and other forums for "hot oil".

Nice man! Sounds like a great day. I was gonna recommend trying 4wd low. That's what I always drive on the sand in. Glad it worked out for you. Keep having fun and off roading!
