Default 2016 jku Rubicon 5 speed auto running 35s on 4.10 diffs

Hey, have you guys had any good or bad experiences with the 3.6 pentastar rubicons running 4.10 diffs and 35s? Mine will be an auto when it finally gets on the boat and makes its way into my driveway!

You will be fine, just make sure to recalibrate for the 35s.
About the only thing you will notice is that crawling will be a little faster than manual Rubis with the same tyre size, but that was always the case anyway.

Mate of mine has the 3.8 manual on 35s and if anything its better in low range for most work as its a lot more useable! No probs on the highway either, but you will need Procal or similar to reset the speedo and auto tranny shift points for the best result.

Clubmate with auto 3.6 on 35s has to keep braking so as not to run into the back of me. I'm on 34s. If I was on 35s too I would still be going slower than him. One thing the auto does have though is Hill Desent Control but that uses the brakes.
