Our first gear ratio is so low compared to previous jeep autos, especially if you had an early jk. That 2.86 first gear is what gave the 3.8L such a bad name in my opinion. If you never drive over 62mph (weirdly specific, but posted multiple times?), go ahead and go deep gears to get 8th gear back. We see 8th all the time on heavy 37" geolander x-mt's. We also set the cruise control at 80mph on road trips. I'd rather keep the rpms lower on the freeway as the 4.7 1st gear will still break the tires loose if you punch it. It's all in how you drive I guess. The deep transfer case gears are more usable when your axle gears aren't super low also.
