Smile Question on manually shift gears on a Rubicon

Hello All, I have a quick question- I own a 2017 Rubicon 6-speed manual vehicle. I just wanted to know, how much 'Rev' I can do for each shift? This is my first Jeep and whenever I shift to each gears, I try to take it slow so that to avoid the vrroooom sound. At the same time I cannot digest seeing other cars cross me without any issues. My ultimate question here is;
1. Am I thinking too much here? Will that be OK if I kind of abuse my Jeep a little and shift fast?
2. Will that bring any transmission issues later?
3. When I shift from 1st to 2nd, the duration is too less for me to accelerate as the sound comes too high- is this normal?

Thanks for your replies, help me as this is my first Jeep.

In my experience, this transmission does better at higher rpm shifts <2500, and should be shifted with some authority.

I don't mind not being first off the line, fwiw.


Sorry, but I don't understand your third question.

Sounds like you need to spend some time learning how to drive stick shift. A lot of it is combination between feeling & hearing. If you're only focusing on shift points on the tach based on RPM then you're doing it wrong. It's fine to look starting out, but that is not the way to do it.

You'll never be first off the line with the manual. First and second gear are just too short for that. It's geared for off road...not the track. By third gear you can put a little speed on. Third, fourth, and fifth can move you along quite well. It's pretty peppy for a heavy off-road vehicle.

One of the things I've learned ('15 JK Rubicon 2-dr), because it is geared so short, is that I don't even need first if I have a smidge of forward momentum going. At a dead stop, especially uphill, I'll use first but I'll always shift into second early. It's going to vary by the traffic situation, but I'll usually shift by 3000 rpm. If I happen to pull out into speedy traffic and I need to boogie....I'll let it get to 4,000 RPM. Really though...above that and you're just making noise and burning gas.

A typical stop sign has me slowing down, downshifting to second, and (still with the clutch out) applying brakes until I'm at a virtual stop, but with just a smidge of forward motion. Then I accelerate away in 2nd.

I'm careful about being too aggressive with first gear at a light or stop sign. It's just too short (perfect in 4wd off-road though). I've had several near rear-end incidents because the person behind me tailgated me away from the light in first....only to nearly hit me when I inevitably shifted and the Jeep paused during the shift from first to second.

The short answer is 3,000 because it's smoother. 4,000 of the semi-truck behind you becomes worrisome.

I've had manuals but the jeep was jerky the whole damn break in. Maybe for 1-3k miles it just sucked. I thought it was me. I found the clutch engagement though was half a pedal length though, vs my cars were at the top or bottom. Then just breaking it in and learning seemed to help. The suggestion on revs over 3500 seem to net me decent not jerky shifts work, but it all depends on how fast you're accelerating.

Your choice on gas mileage versus acceleration... Shift <2500 rpm better gas mileage. Shift >3000 rpm better acceleration.

Agree with the above statements.
The 3.6 seems to like to be above 2000rpms, so, shifting around 2500rpm seems to drop it back down to ~2000rpms. The engine likes that. The torque "curve" is pretty flat from ~2000rpms on up, so, for normal driving simply keeping the revs above 2000rpm on shift recovery works well.
The horse power really comes on after 4000rpms, so, if you need to really get on it shifting up around 6000rpm works well, but, 2 things suck when doing so. 1, the engine hangs rpm between shifts and that is annoying... 2, the trans doesn't like being shifted up there, it gets really notchy/blocky, so it's simply not rewarding, my opinion. But, driven in anger it hustles pretty good... for what it is.
The vroom sound... especially at higher rpm, is again the computer hanging the revs between shifts... not sure why it does this, at any rate, I find when driving normally, before you push the clutch in to shift, slightly let up on the throttle, just enough to stabilize your speed for a split second (or cease acceleration for a split second) in the current gear, then shift, and return to the throttle for acceleration.
Seems to me if the compure sees active throttle prior the shift it will hang the rev's, however if it sees the throttle is "neutral" or, maintaining current speed for just a moment, it will not hang the revs.

Good luck.

whadda you mean you will never be first off the line with a manual? I am always first off the line... even can manage to keep that first place for 20-50ft sometimes even longer...(if the other guys aren't trying... )
JKR +4.10 is fairly zippy off the line...
revs up to 5-6K pretty quickly...

Good advice to the OP/JK newbie. To engage a smooth transition from a stop to motion, even my passengers noticed I'm less aggressive with first gear in a JK. Daily driving I shift at 3k and 4-5k when I need some of that 285hp. Overall its a great DD for me. Just takes some practice and getting used to versus a lighter import vehicle.

Perhaps it depends on the package, but my '17 Rubi has green line segments indicating the optimal range for Eco driving (1k-2.5k). The 4.1 Rubi has enough torque and doesn't require many RPMs to keep up in normal driving. Unless I'm in mud or sand I keep it below 2.5k. Regularly get 17.5-18 mpg.

That being said, the low gearing also means that you can haul ass, or peel out through third gear. If that's your thing...

I drive a stick and have for years. When I got my JK had some trouble with it. could not get the feel of it. Then I found out its a fly by wire on the gas paddle. Took me a bit to get it but now she shifts smooth and have no trouble with it. Welll she is touchy off road with gas cluch but I'm sure that's me .

I'll let others speak to the other points and just say you might as well start working on changing your mindset on this right now. Doing so will serve you well no matter what vehicle you're driving. You're in a Jeep. Relax!

If you turn off Hill Assist when city driving you will have a much better experience off the line. It's a great feature off road, but a big P.I.T.A. at stop lights.

Thank you so much. I completely agree with you. I had this similar issue happened many a times now. Now after realizing it (a 2 second delay when shifting from 1 to 2) , I now use the right most lane or slow speed lane in the signals, so that not to make the driver behind me giving me a glare.
Even at 3000rpm, sometimes when I shift from 1st to 2nd, I feel a nudge or sometimes even the car shuts off. But I think, it is mostly the way I handle the clutch and acceleration point. I know I am getting used to it now. It is exactly a month ago I purchased my dream Jeep. I am sure I will become better.
Thanks again for your words!

3500 / 4500 rpms is about right. Come on guys this isn't a low reving big block.

I have the same, and so far I stick to the green line segments and sometimes especially while moving from a stop signal light, I go up to 3000rpm. So far I get around 17.5 mpg. Since the Jeep is a month old, and I being driving a manual after a while I guess it will take some more time.

I am wrong with my statement when I said 'I feel bad when I see other cars cross me without any issue'. Because, I clearly know that I was kind of not so prepared to drive the manual. That being said, I love manual driving, be it any vehicle. Especially I always wanted to own a Jeep with manual transmission. Only thing is this is my first Jeep that has manual transmission. Also since its new I felt like I am abusing the vehicle. But now I understood what I need to see from the previous comments from my forum friends. Thanks for your comments too!

I've driven manual transmissions for decades. Every one is different and takes some getting used to. Once I got used to it (my '16 JK) I turned the hill assist off... and, for me, with "normal" driving I shift at around 3k for every gear, and blip the throttle when downshifting.

I don't think your going to cause any unnecessary wear so long as you aren't grinding the gears or over-slipping the clutch (or downshifting to early) on a regular basis. And don't always rest your hand on the shift knob.

FlyFisher590 basically said everything that I would have typed. With one exception. I really find my self skipping 1st all together about 80% of the time. Even from a dead stop. As long as I'm sitting flat, or with a slight downhill when stopped I start in 2nd. My commute is 45 miles with about 25 of that being bumper to bumper interstate. Using 1st can get the Jeep rolling but then I'm hitting 2nd all for maybe for 100ft of forward progress before I'm clutching and breaking and back to Neutral sitting still for a while. I'll start in 2nd and save a shift.
