If the intent is improved efficiency, I am not sure the Tremec is the best option. Like I said, in the Challenger which offers both the Tremec 6-speed and ZF 8-speed, there is a significant fuel efficiency disparity between the two transmissions. So if efficiency is the goal, I don't think there is anything to be gained from the Tremec 6-speed.However, something to remember, while the Tremec is a bit heavy (121-146.2lbs vs 89lbs of the NSG) and longer (shouldn't be an issue now that they are making room for the ZF-8), but the Tremec could still be an option as it would be able to handle much more torque (580-880NM vs 400NM). The thing is that they would have to adjust the ratios dramatically currently the NSG 370 is as follows from 1st-6th : 4.46/2.61/1.72/1.25/1.00/0.84 whereas the Tremec's best low-range of their 6 posted on their product pages, is: 3.01/2.07/1.43/1.00/0.84/0.57 which mean a terrible crawl ratio without offsetting with massive axle ratio, which kills the benefit. What you would want is a wider spread not just smaller ratio in 6th. Having a spread from 4.0x - 0.6x would be a good balance IMO, and Jeep could have it configured that what if they wanted.
True, but like I mention, that's with the current ratios, in which the spread it terrible. In order to make up for the tall gear ratios they currently use in first (2.x-3.x) they would likely have to have a higher/shorter axle ratio in order to still have good acceleration, but that would mean they kill fuel efficiency on the highway, and to do it the other way around and have good highway fuel efficiency then they compromise the acceleration and low-end power delivery.If the intent is improved efficiency, I am not sure the Tremec is the best option.

LOL! Yeah, that would be awesome, and even more fun to watch someone encounter that for the first time.I hear the new manual tranny will have a splitter.
Lets see in my youth I have driven "3 on a tree" not real good at it, 4 speed, 5 speed, haven't tried a 6 speed yet, cant imagine all the shifting for an 8 speed.I posted this in another thread, but it seems germane to this one as well, ZF is making a modular 8-speed DCT transmission, developed by the same folks who made ZF-7 which has a manual option, which opens the door a sliver for the possibility of a modular manual 8-speed;

Still doubtful, but it might be a mid-model refresh of be in time for the launch of the Pick-up.
Pretty much agree here. The only thing I would add is that hypothetically, manuals get better efficiency than autos. If you look at a case-by-case basis, then yes, sometimes the AT gets better efficiency than the MT in the same car, so you can't necessarily make a generalized statement.Old Manual vs Auto isn't the same as New Manual vs Auto.
Previously you had scenarios like that found in the YJ with a 5-speed manual, and a 3-speed Auto, so the ratios & spread favoured the manual heavily, which is still somewhat present in the JK despite moving from a 4-speed auto to a 5-speed auto. However if we're stuck with the pokey NSG370 vs the 8-speed auto, I'm not sure that even the most experienced and smoothest of us gear rowers will be able to match the efficiency provide by a wider gear ratio spread, without auto rev-matching found in new manual transmissions.
The idea that all manuals would outperform all autos is rather simplistic, considering strapping in a 3-speed T-90A vs even the W5A580 let alone the ZF 8-speed, and you'd have trouble keeping up.
It's one thing to compare similar number of gears, but if there's a major imbalance in either numbers or spread, then it's hard to believe you can make up for that with your SSS Super-Shifting-Skillz.
I have driven both 5-speed and a 6-speed Wranglers. I don't think the 6-speed is any more difficult. I have also driven an F-250 diesel with a manual transmission. The shift pattern looks like this. Note I used periods as placeholders to show there is no gear in that position:Lets see in my youth I have driven "3 on a tree" not real good at it, 4 speed, 5 speed, haven't tried a 6 speed yet, cant imagine all the shifting for an 8 speed.
