There are shift points listed in the manual. It’s in mph and not rpm which I suppose is a form of dumbing down the instructions. The shift points are 15 mph from 1-2 and 24 mph from 2-3. When I shift from 1-2 or 2-3 I give a little gas pedal when the clutch grabs just to smooth things out.

Some other things to consider, IMO.

Turn OFF the ESS.
Turn OFF the hill assist.

IMO this leads to a more "normal" feeling clutch. This engine loves to rev and I've rev limited it a couple of times when my music is too loud and I'm not paying attention... lol.
For 1st - 4th I will almost always take it up over 3k rpms before I shift. The 3.6L does not come alive until you are above 3k.
For what it's worth I'm running 37s and 4.88 gears.
I read this post today and thought it sounded pretty far fetched but I would give it a try. It really does make a difference in how the manual transmission shifts. I can "feel" the engine now since I turned off the hill assist! Not sure how to explain it, but you can tell the difference.

Thanks for the feedback. It seems to be 50/50... guys like you and me can see a notable change where others can't tell a difference. I'm pretty sure they are millenials and have no idea how a real clutch is supposed to feel ;)

Well really this clutch should not be how you Boomers think a clutch should feel haha. I don't think I ever tried this on my Rubi so when I go for lunch I might try it again. I just don't even understand how it would make a difference.

My suspicion is the brakes. The hill assist is designed to grab and hold the brakes when you are on a hill and it does that very well on both manual and auto Jeeps. MAYBE it also puts a tick of hesitation into the clutch or rpms so that the brakes have time to let go (that part is just a theory).
Regardless, even on flat ground, there is this odd sense of delay or hesitation which gives the clutch a very unnatural feel.
As soon as I turned hill assist off and drove for a min I could tell the difference.

Where do I find how to disable hill assist? I just picked mine up about 10 days ago. Have barely driven it. Less than 20 miles since I got it home. Just been busy. Anyway, I can't find anywhere how to disable the hill assist. Can you direct me where to find it?

I have been driving my JLUR 6 speed for a week now, my first Wrangler. I love everything about it but one thing, the shaking between 1 and 2 gear. I have driven manual cars for my entire life (I was born and raised in Italy, now live in Houston). I am at the point that I sort of regret going for a manual...
I haven't gotten my 2021 yet but with my 2005 I didn't even use 1st gear and didn't need my clutch replaced until 230,000 miles so it must have been ok. I am curious to see how the 2021 feels.

I find that I can shift to 2nd without revving too high as long as I don’t need much throttle once in 2nd. No lugging. It’s when you try to apply too much throttle in 2nd at too low a speed that the lugging begins. Level ground and not in a hurry versus needing speed (let the rev climb).
I do love this transmission though. 4L shifting indeed requires a different shifting style, but hopefully you’ll get the hang of it with time.
I do find that after a lot of 4L driving, going back to 2H requires a few hours of driving before lugging - that wasn’t there before - dissipates.

On the radio touch screen go into settings and I think from there is is either "system" or "safety" and in that menu the last option will be enable/disable hill assist.
I turn mine on when I am off roading since it is great to have when you are stuck on a boulder but for daily driving I keep it off.

Awesome. Thanks. I haven't even played around with the touch screen, settings, etc. It's on the list of things to do, but I'll definitely go in first chance I get and disable the hill assist. Appreciate the help!
