M/T a bit frustrating

[AnnDee4444]

Try to find a used half ton with an N/A V6, good luck.

What about the S-10, Ranger, & Tacoma?

It has a power band and below 2000rpm it ain't in it.

You are correct, look at the dyno chart: below 2k you are making 25HP and less than 75ft*lbs of torque. Between 2000 and 2100 rpms you gain 25ft*lbs and add 25HP (double). I know it doesn't take much to keep a vehicle in motion, but this is why this motor bogs under 2k. It is just enough power to keep the Jeep moving and that is it. Again, like you said, watch the instant fuel consumption. You will actually get better MPG at 2200rpm than 1800rpm.

That dyno pull looks to be pretty inaccurate in the lower RPM range. Assuming the manual tune has the same power output as the automatic, 2000 RPM = 208.2 lb-ft of torque & 79.2 HP.

Those are not half-tons. Full size trucks out-sell mid-size by a 5 to 1 ratio for a reason.

 

[word302]

Yes, and it's been great except when I was buried in wet snow. Too gutless to keep wheel speed up. #notorque

Try to back up a 2k lb trailer on a slight incline. You'll either a. slip the clutch the entire time, or b. go way too fast to be safe.

Back mine up a driveway all the time without issue. Sounds like you're a rookie backer.

The rev hang is the worst I've ever seen. Would love to tune it the hell out of there, is that difficult?

I've looked on line for a remedy but so far they only have it for subaru's and honda's

I would guess the slishbox is going to sp3nd a fair amount of time shifting the way the torque curve is. The z8 will be trying to maximize mileage and always ready for user input. All those gear changes might feel seemles, but I wonder later on down the road.

The manual has taken me about 2000 miles to get good with the clutch and the gearinf while learning the torque curve. Now I really can enjoy my manual now that my brain is trained. The manual does shift nicely. Soon to have Amsoil or Redline to make it even smoother.

I towed a bunch with my 4cyl yotas over the years, and i just learned to pop it in 4 low real quick when I needed to back up a steep slope. Was great with locking hubs, but really no big deal otherwise (as long as you don't turn too sharp). Even now when I back my 8k lb toyhauler up my steep driveway in my 5.7 liter tundra I use 4low. I love gear reduction.

HAHA nice troll.

This subject came up in another thread and multiple people agreed, backing up a trailer on an incline is not ideal. Reverse is too high-geared. With kids around it is not smart to back up very fast.

True, that is probably the best way to do it, in spite of the little binding we'll get if on pavement.

So because I don't have any difficulty backing my trailers up an incline I'm a troll? Ok boss.

Well, if anything this proves my point more. The 3.6 has plenty of torque.

You’re right on the money 8flat. To be safe when backing up a hill you should take it slow which in turn causes the clutch to sometimes slip a little. I’ve been there, it’s not fun knowing your clutch disc’s slipped because you can smell it. With that being said, 805dirtdog had it right. When I go to my brothers house he has a steep driveway and I prefer to back in at daylight so as to drive out at night. After slipping the clutch once, 4 low and zero slippage.

You guys realize that reverse is significantly lower in the JL than it was in the JK don't you?

Agreed, I just did this last weekend with a trailer. 4LO is the way to go. Strange we need to do that but oh well.

Holy crap that's nuts if true.

Is there some strange reasoning I'm not grasping here.....some factor that jeep engineers took into account that made them choose such tall reverse gearing? I'm at a loss for why they'd do this. Maybe since 4LO is so crazy low, they need a taller reverse gear so you can actually get some wheel speed when backing up in 4LO?

It's a 4.49 reverse. Hardly what I would call tall.
