Hi guys the other day i took my rubicon 2007 to a mountain for a little fun and i notice that went i put the 4lo and the transmition in drive down hill i dont know if its the transmition shift to second gear or its that the difenrential disengaged but it starting going from 2 or 4 mph to almost 12 and it looks thats if i didnt apply the brakes maybe past de 25mph. i remember my old 2004 that went i put 4lo it almost stop and i felt secure everyway i go downhill. its this common on the 2007? or its mine. please let me know because i think this its a safety matter. thanks

 

If you want engine braking with an automatic transmission, you will need to put it in 'Low'. Leaving it in Drive will allow it to shift gears automatically.

Like Sv650 said - use the gears just like you would in a manual. In 4 LO/1st gear you'll crawl down anything.

First time I took mine out in the woods to test all the toys I couldn't get the lockers to engage in 4 LO. They kept blinking at me but wouldn't lock up. About 30 yards later the transfer case popped out of gear. Learned the hard way where low range really is!

 

Yep, these guys are right on. Autos do that in all type of 4WDs. My FJ40 with a TH350 does that too... Just put it in first and you are good.

 

thanks a lot guys i appreciate the response i know now thats the promblem of my jeep was the parts behind the steering wheel.
