Its not always power that makes a car faster....adding 3 gears makes a world of difference espescially with a vehicle this size, and the power it makes...For the last 1.5 years around here and the other site, what I stated was a common statement made about the 8spd. Most all of the conversation about it has been for gas mileage purposes. More-so than it being fast. Which, BTW, in real world I will bet the 8spd is not going to be that much faster. Once again, adding a couple gears isn't going to make the same vehicle, with the same weight, and same HP, that much faster. How many times do you see the first mod to add power/speed, by any car person, to be "change the transmission to more gears?"
Actually white 6.4, when the 2012 came out one of the main complaints on here and other sites was that it lacked the 8 speed. The main reason was for the gas mileage. Almost all the posts said, not buying the vehicle for good mileage *but* why not put the 8 speed in so that there is better mileage if Chrysler already has the 8 speed.
Haha. It was long before your time here, lol. One of the biggest complaints of the 2012 was that it didn't have the 8 speed. Back in the spring of 2011.havent seen those posts, and it would surprise me that someone buying a 5000 lb suv with a 6.4L motor would be trying to figure out ways to get better gas mileage, there are many other economical choices (mpg wise) v6, even 5.7. bottom line is dont buy an srt if you are worried about fuel economy.
