How many times have you changed the filter/fluid?

You got me there but with 10 inches of snow on the way that dream of the top being off again is the only thing keeping the keys in my pocket!

So i am the only on that thinks changing the rake will help a little bit ? lol

In theory yes, along with that plastic air dam. I wouldn't think of it returning to stock performance though. Your working against weight; rolling resistance and aerodynamic drag. And that's with ideal conditions. Good luck.

Thank you very much I'll order some new coils for the rear when I get the time and money and I'll report back

The issues listed above sound like tranny.Shifting back and forth looking for gears sounds like maybe valve body.We had this problem with our Wagoneer

Funny reading this....I have an 09 JKU, 42,000 km, 33 inch tires, Terraflex budget lift and 1-1/2" body lift, Procalled the tires into computer, jet pcm module..........and I was just in Cadillac MI a few weeks ago on a windy day, going through the hills (I live in a super flat area) and the tranny was hunting so much I thought it was going to blow. I have been putting off a re-gear, but I think I might have to re-think that before the transmission blows/overheats (going to install a trans. cooler also). Changing the whole rear end for me is overkill, as well as more $$$ than I am willing to spend, but a re-gear is in orger so this brick can get better MPG's on the highway!:giveup:

I am going to look in to this. This sounds like it could be it. Thank you
