First real tow with the manual.....not good

[bleda2002]

I didn't consider the torque based on mode, so I probably stand corrected. If the maximum torque is only available when using full electric, then yes - not very helpful. I will have to read more about the modes and exactly what power is available when. Regardless - even the 290 ft tq would be an improvement though that's still an anemic engine compared to the other midsize trucks these days. The Colorado, Ranger, and Tacoma appear to be offering very stout numbers in gas engines.

But, I could commute with the full electric five days a week in a future 4XE Gladiator.....but that's a different topic.

Its 200 ftlbs and 110 horsepower over the 3.6 and its available in all modes at all times. This is a common misconception that the batteries go flat and you lose the power but you dont because it always keeps its batteries at 15% to keep the electric power adders available.

Exactly and with hilly driving, there's a lot of electrical savings and recovery going on.
One only has to watch the dial or put the system's display up on the radio and you can see the power flow in or out and where it's coming from.
We had some issues due to the mountain driving and the strong wind against us for a good 15 hours of driving where it wimped out and the mpg sucked being only about 15-16 but that was not typical.
When the torque or power isn't needed, it uses the engine to generate power and put back into the batteries. Unless you really pay attention, you just don't see that.

Wow, with my stock Overland automatic, I could take the 2% grades at 65 and 3300 rpm fine, and the other grades it dropped down and hit 4300 rpm or so to make the hills, but settled back down, and on the level it was in the mid-2,000s.
Something is really pulling the power back on that.

I have to agree with your observations. I averaged about 15+mpg cross country with a trailer last year. I did not hit 8th very often, typically flat highway cruise the trans would settle in 7th, say crossing Wisconsin, Minnesota, South Dakota (when there wasn't a head wind) and the inter mountain flats of Wyoming.

It was a new truck and I didn't want to push it but even on steep passes the JT could accelerate satisfactorily when asked. The MPG would drop sharply to the single digits however. At least the V6 is smooth enough that 4-4.5k RPM doesn't sound abusive.

DUH! LOL

Like many of your useless posts...completely worthless.

Something definitely seems off. Sure the frontal area, less gears than the auto, lift, tires etc. will take it's toll but what you are describing couldn't be more night and day from what me, SP and many others in this section are experiencing while towing much heavier/bulkier loads than yours. Esp that gas mileage number. Lowest I've seen at the 6k limit is 12.5 in hill country. Could you have much more other additional weight in your Jeep (I see the tent and rack). Could you have some kind of drag in the drivetrain (do diffs get really hot?) I also have a throttle controller that does allow me to fine tune the throttle response when towing (HikeIt but they are all the same).

Here is the real world 6th vs 4th on flat ground cruise was set for each. So the majority of my trailor pulling was in 4th at 3100-3200 rpm.
I agree that is to the low side of optimum for power band, but it didn't make any notable difference if I ran it in 3rd at 65mph. I'm just summarizing she just don't got it. I am going to have my friend with a stock max tow hook onto it, because I'm not buying that will hold 65mph on a grade, and, if it does by some miracle, I bet it's at 5k rpm or better. That's just my theory, yet to be proven.

If it's really no better in 3rd, something has to be wrong to be pulling that much power.

You are also rotating 37s.

Well to be fair, so was yours. OP and probably everyone with a manual doesn’t really care what the diesel does.

 

[ShadowsPapa]

I only bring up my automatic as it's still the 3.6 and has the 3.73 ratio to give a comparison to what these should be capable of (stock form in my case other than more rolling resistance from the tires than stock would be)
The engine "should be" the same as far as HP and torque - however, at what point does it trim the torque to protect the clutch.........

(As to the other - I bet some people are a real blast at parties, or when at an event, hates it when any other topic creeps in)

Don't be jelly of the power of the diesel. Also it's great help for those that want to really tow with the JT. It's either go diesel or have problems.

We definitely don't care about your opinion on towing in this thread and I can assure non of us are jelly of your POS ECO diesel with its $100 oil filter and other ridiculous things.

Please tell us how you really feel lol. Here, on this doll show us where the bad diesel touched you. $100 oil filter?? Umm nope. But hey is get the butthurt if you couldn't afford the real engine. Can't understand why someone would settle on an engine as underpowered as the 3.6.

Conversely, I can't understand how someone could choose a Jeep with an automatic. Choices, my friend. Choices.

Anyways. Back to the thread about manual transmission JTs and their abilities regarding towing...

What, can't afford OEM parts?

Ok, lets try to stay on topic. I'm not trying to switch to an automatic, or electric, or diesel.
My hunch is, and no one has had a satisfactory answer yet, that the throttle body is not even opening 100%. Given that there is zero, audible change in intake noise, exhaust note, or rpm change from 1/2 pedal to WOT under load. I have NEVER experienced that in any vehicle. As far as the tent and rack goes, I listed the weights in the first post as I was overly concerned with the weight on this first trip. I was at or under the recommended capacity and tongue weight. The truck sits at 14.5-15.5mpg with or without the tent and rack. The truck is my wifes daily, 40mile round trip for her. The gears have been in for a year now, with 15k or so miles on them with no issues.

Nah, I'm more jelly of the diesel's suspension problems, fuel pump problems, heat soak problems, derating problems, etc. The 3.6 is by far the most reliable engine option you have. But hey, to each their own, right?

But none of that matters here because the OP is towing with a 3.6 manual. The diesel has nothing to do with his situation and it's useless to bring it up. I do hope, though, that you succeeded in making yourself feel better.

Back to the point of this thread, I do believe it's the way the Jeep is handling the manual transmission. As @ShadowsPapa has shown, the automatic with the same engine isn't facing these problems. And the manuals have been known to have been power restricted due to the questionable design of the clutch. The "fixes" for the clutch issues have been to restrict power in high-risk situations, and I'm sure high-load things like towing fall in that category. We also know that the truck can "detect" when it's towing and can change things (like shift points in the automatic) when it does. To me, it all adds up, and should you find that something like the throttle body is in fact being restricted, I wouldn't be surprised if that leads back to an intentional restricting in order to preserve the clutch.
