[QUOTE="Jockey 19, post: 458517, member: 25081"] 2010 JK Unlimited 4x4 Sport . w/3.8 - 373 gears and Automatic Transmission. Finally got the tires and wheels installed as well as the 2 in puck lift and jeep looks GREAT !!! The Jeep came standard with the 225/75 R16 tires and I replaced then withe 285/70 R17 - Basically going from a 29in set up to a 32in set up.

Only thing I have noticed is when I get the Jeep on the highway, it likes to hunt gears when in Overdrive. Basically, at 60-70 mph, it is trying to cruze at around 1700 RPM and with the slightest incline, it will downshift. I have heard of people buying a chip or having 4x4 shop re-program transmission shift positions to improve this condition. Just wanting to get some opinions on this. My speedo is a little off, but I am not as much worried about that as I am the transmission. It is not awful, but it seems to be difficult for it to stay in Overdrive.
