Oooo. Dunno if I have your answer, but I'd love to contribute... JKUR, manual, 4.10 (stock)
Lets forget mood for a second... I'm sure everyone here could bounce off the redline right up to 4th if they want to haul ass. Woo.
Know what you mean about screaming. I typically shift soon and often. I'll be in third by the time I'm through a big intersection, and typically shifting before I leave the "green" on the tach. Sometimes I use 1st just enough to initiate a roll and then move on to 2nd. There's an art to not lugging the motor though given variables like weight, velocity, and inclination.
So... a preface: I am by my own account a decently skilled pilot. I have 26k miles on my 2013 JK now. At least 100 of those miles are in traffic, slightly uphill, at 1mph, downtown Los Angeles, during the worst hours, while flossing and texting my dog...
So it's with some trepidation that I put this out there: I have a very hard time shifting *smoothly* from first to second. I watch my passenger's heads sway on every 1->2 shift and yern for the perfect shift (1 out of 504). I'm probably doing it wrong. Would love some advice.
So where do I typically shift? I'm not a huge fan of slow... so slightly past the "green". I agree, it's kinda noisy. I guess that's the gearing for you?
