Had some questions for you fellow manual owners. I have noticed three things that I thought were odd at 4k miles on mine...
1. If I am on flat ground, i dont need to give any gas in first gear to take off if i take the clutch out very slow.
2. Any incline or I need to take off like i would in other manual vehicles (not fast but normally), I need to get up to about 1300-1700 rpm before releasing the clutch. 1k under these conditions is close to stalling out/i feep like im riding the clutch. My dad is a truck driver and car tester but didnt think that was odd.
3. Reverse gear feels way too fast

I owned a manual frontier before this, and I thought that the three above items were odd. Ive had zero codes, and i have the updated controlcode. I love it otherwise and dont regret it at all.
Sounds like you're just learning your new stick shift vehicle. Every one of them is different. Most every manual vehicle I've ever driven will do number 1, in my experience. That's completely normal. It's a jeep with a short first gear, and it's meant to easily do a slow crawl offroad, so #1 might be more pronounced than other vehicles though. Even moreso if you have the 4.1 final drive. But as far as I know, every manual will take off if you slowly reach the engagement point of the clutch.

1. Much of that is to do with the very short first gear.

2. I don't experience that so much. What size tires and axle ratio are you running? Remember, too, mine is a JLUR and is a bit lighter than a similarly equipped JTR.

3. Yep, it is really too tall, IMO. I'd love for it to be quite a bit shorter. I'm getting ready to re-gear to 4.56 (35" tires) and I am sure even then I'll feel reverse is too tall.

One more thing....You really own a Pinto? If so, that's pretty cool! I haven't seen one in years!
33" Mud terrains with 3.73's. Edit: I made this account quick to ask a question on the forums, so I just put a vehicle in. I drove my dad's while growing up, which is rare that one lasted until the late 2000's lol.

Ok, that winds up with a bit taller gearing, but not terribly taller. It probably performs about like my JL with 35's and 4.10 gearing. But again, it is a heavier vehicle than the JL. I can see more slipping to get going but the 1st gear is still pretty short. I think @NachoRuby is right that you are still getting used to it. Drive it around a bit and see how it goes. Most of the vehicles I've had for 35 years were manuals and every one of them had unique quirky behaviors that took a bit to get used to.

1 - perfectly normal. Especially when you first start it up. Idle is a bit higher.
2 - depends a bit on axle gearing but sounds about right. The 3.6 has very small torque off idle. Needs a little gas / RPMs to get going.
3 - reverse is a bit hi/ fast. Also depends on axle gearing. 4.10 Rubi is a bit slower.

Good luck

yes to the manual. Right now it feels like this is how it should have come from the factory with my rubicon takeoff rims/tires (32.7 I think). I’m hesitant to go with a much bigger tire since then I’d feel the need to regear again lol.

If your goal is a 35”, id say go 4.88, 37 the 5.13. But if you’re in a mostly flatland area, you might have different results.

but I should point out, as much as I love my manual transmission (I custom ordered it exactly how I wanted it), when I’m on the highway with the cruise set, I don’t want to have to change gears to climb a hill. So my goal in regearing was to mitigate that, which it has helped tremendously.
I get that no shift cruise. In rolling hills Ill often just leave my 4:10/33s in 5th. its close to what 4.56-6TH would be. Using the gear-calculator you can simulate a hwy cruise by picking the gear closest to you calculated tire/axle combo and get some idea of what the hwy cruise will be like.
