I've come to the same conclusion based on manual vs. auto owners experiences. I think overall between both tranny's one should expect a decrease in fuel and power efficiency after installing bigger tires. Having 2 more gears in the auto does allow for better selection of gear for a continuous powerband throughout the speed range, resulting in not having to pay attention to selecting the proper gear to keep from bogging as you would with a manual. The auto is still going to have its work cut out for it searching for gears, especially if you dont recalibrate for tire size. Unless youre paying absolute attention to the auto shifting, you probably wont notice the auto gear searching as much. Us MT's gotta accept the fact that manual means "work", and it will require mental/physical work to maintain efficiency when driving...just more of it if you change any dynamic over stock. That's part of the fun...right?
for me since I don't own one yet I have to plan it out. I want a rubicon model but without alot of fluff. In my head I say "ya know the good stereo would be cool" so if i save 2k on a manual i can justify the stereo. In the end Ill have to see what fits the best. My wife is adamant about getting an auto "incase I want to drive it" but she never will. She has never driven my k5 blazer or my ford fiesta. She just got herself a new vehicle (Chevy Traverse) and she has some apprehension driving it. The gladiator has a 17" longer wheelbase and 14" longer overall than her Traverse. She will not want to drive it I am certain. I am also certain she wont be able to park it. :CWL:
Really for me I just need to really think about how it will get used. I plan on it being more of a family / errand / weekend warrior vehicle. Jack of all trades which is what I think the Gladiator is really good at anyhow.

you and i are in the same boat. My fiance comes from a jeep family, but has never driven manual, so shes mixed excited/apprehensive about the opportunity to learn. Im hoping she takes like a duck to water with it in case she needs to operate it, but im kinda thinking ill be doing most of the driving (not upset about that)

Yeah mines a bit the opposite, she doesn't want anything to do with a manual. Lol
She likes to be accommodated > my preference. But auto isn't a downside necessarily. Improved tow rating, programming flexibility, bigger tire friendly etc.

The automatic is definetly a downside. ;)
i was going to say, less fun. but decided not to.

I think the requirements for getting a Manual Gladiator are

1. you want to shift and third pedal
2. you need an anti-theft device
3. you don't need to tow more than 4,000

------------------------------------------------------------------

My biggest recommendation, get a Sport S with no Tow Package as that will give you max payload (3.73 final gear)
or Manual Rubicon as you will get the 4.10 final gear

The Overland and Base Sport in Manual are very gimped with only 1,100 Lbs of payload.
-------------------------------------------------------------------
The payload of my Sport S is 1,647 or 747kgs

This is my concern. EVENTUALLY I want to go 37's but im thinking you would nearly have to regear for the manual unless, like you said, you just want to have your funds go out the tailpipe. I know the auto you can go back and adjust gear ratio and things, maybe even shift points I dunno. It just seems like the auto may be better when going beyond stock tire size.
I wouldn't say so. Got almost 1,000 miles rolling around on 37s with stock gears, and now that I'm getting used to the transmission, I'm very happy with it.

Dollars leaving is having a heavy foot instead of using the gears and going easy.

To be fair, I haven't driven an auto since I wasn't interested in them, so they very well might be great. But I wouldn't be afraid of a manual and 37s with stock gears.

Unless youre paying absolute attention to the auto shifting, you probably wont notice the auto gear searching as much. Both are at an advantage for increased tire size if you have the max tow or rubicon package with the 4.10 gears, but 37"+ you may need to start planning for upgrades if youre worried about maintaining fuel and power efficiency. Its a truck, and its a jeep...neither have great history of fuel economy, though the efficiency trend is upward in recent years. Us MT's gotta accept the fact that manual means "work", and it will require mental/physical work to maintain efficiency when driving...just more of it if you change any dynamic over stock.

Sure is fun. I look forward to driving it even for mundane things because it's engaging. Not just hop in, D, pedal on the right.

Said this before, but I think it gets great mileage for a lifted 37 inch tired rolling brick. I pointed out some interesting foibles in my learning a new transmission, but that was as much me as the transmission. It's got plenty of performance to roll it's 37 inch tired brick-ey self around. I'm nothing but happy.

Crawled around in 4 low a little tonight just for the heck of it. :)

I think this post would put a smile on anyone’s face... even an auto roller

Fun wise is preference.
But on paper I'm not seeing a downside and I love manuals.

@chrcal14 what sort of MPG are you getting with your 37" and manual? City/highway

I had ruled out 37" almost completely until i saw your post, doesn't look like you have any regrets.
Also looks like your total tire/wheel combo is fairly heavy since you're running 20" rims (i could be wrong), do you know the weight per corner?
I'll be going with 17" wheels.

They're 17s. AEV Pintler JLs. 112 lbs per wheel/tire.

I can consistently baby it around at 17 just back and forth to work, 10 miles each way, engine barely gets warmed up and a mix of back roads and highway.

Given a bit of heavy footing to run the engine while new, and a long trip back when I bought it with wrong tire size calibration, I think it's at 15.8 on trip meter B that I never reset since new.

I haven't taken a long ride with the tires properly calibrated yet. I'm assuming a slight improvement.

I knew I'd lose a bit over my 5.3 Silverado, which lifetime averaged 18. I'm good with the trade.

For perspective, even at 15.8 vs 18, at 10k miles per year which is about what I drive, that's $234 per year in extra gas at $3/per. Worth every penny.

i will be downsizing from a '14 Silverado and i drive 10 miles to work as well, and im sure my transition will be more than easy, but i still have that back of the mind feeling of "what am i going to be sacrificing"... but then i remember i dont tow much and i can do more off the beaten path stuff with this jeep than i can in the silverado...ill take the $230 fuel economy hit with a smile.

I traded my 14 Silverado v6 on my Gladiator. Only thing that was lost was the size which was largely unused. I live 3 miles from work so basically was in the same boat as you. I haven't paid a whole lot of attention to mileage but I feel like I am getting better milage than the Silverado had. I find myself filling up less frequently.
