Come visit Denver. It's nearly as flat as Jersey and the traffic is getting to be about the same. You should feel right at home.Most of the driving I do is on side streets at lower speeds, if I had big tires and lived in Colorado I would shift about 1000 rpm higher! It's pretty flat in my area of Jersey...
I have no problem shifting at 2k-2500 with 4.10s and 6 speed on 31s. Never struggles or lugs. Most of the torque feels like it goes away after3k anyway. I have my hotrod, and it is quite a different story when I drive it. I see no need in revving an engine like the 4.0 above 3300. It just doesn't make sense to me. Time will tell, but I have 265,000 miles on my pickup and still going strong and I drive it the same way.I think gearing and tire size are factors as well. 3.73 gears with the 6 speed pulls strongly in the lower gears between 2000 and 2500 rpms with somewhat worn 31 inch tires .
Around 2K under light load. Even earlier if you are really light on the pedal. I can drive my 42RLE around all day up to 65 easy without breaking 2K.When do the automatics like to shift?
Recommending to shift with the shift light is laughable. You'd be sitting at 1300 RPM all day long.Around 2K under light load. Even earlier if you are really light on the pedal. I can drive my 42RLE around all day up to 65 easy without breaking 2K.
Jeep programmed the transmission and the shift light based on wear data and fuel curves for the 4.0, not internet voodoo and wives tales. Follow Jeeps advice or some dude on the internet. Somebody always has a good story about why they are correct and the folks that designed the engine are wrong.
