As far as I can tell, at first they will come with the 5.7 and a 6 speed and 4:10 gears, but will eventully (late availability) come with the 8 speed and 3:92 gears.
The question is, should I get one with the 6 speed or wait for the 8 speed?
i don't think anyone will really know until we see how the 8 speed trans holds up. Sure an 8 speed trans sounds good for gas milage but it sure would be shifting quite a bit when driving inner city.
Personally I would wait until the 8 speed rolls out. If you want to get an idea of how the 8 speed handles being tested, go test drive a charger or 300 with the 3.6 pentastar that has the 8 speed transmission.
The ratios that will be in this transmission will make the truck faster off the line while getting better MPG's.
Correct me if I'm wrong. But I believe the new 8 speeds two first gears are for towing purposes which mean better launching and getting up to 60 quicker. That's how they can get a new charger with the v6 to 60 in 6 secs. And you have to think that car is only 300 pounds lighter than a reg cab express. So I'm sure the 2013 rt will be a whole lot faster than a 2012
I'd go with the 6 speed (really 5) if you're going for performance. Assuming the case size is the same dimensions, there will likely be less room to to add more clutches with the 8 speed. That is just a total guess, as I don't know what the specs are on the 8 speed.

2009 & 2010 i believe had the 545RFE transmission, it was a 5 speed
2011 & 2012 had the 65RFE transmission, it was a 6 speed
both had the same outer housing
the R/T had a different torque converter, than the rest of the models & i believe it had a 4:10 ratio rear differential

scroll down to the NEWS, i think it is the 2nd line down
i posted what i could find out about the 2013 models
2009-2012 are the exact same transmission. All they did was retune it for 2012 and rename it. It's a 5 speed with a split gear so essentially it's been a 6 speed since 2009

This will blow all your minds....the 545RFE and 65RFE are actually both 45RFE's which was the 4 speed trans. All chrysler does is change the pcm program and BOOM new gears magically appear. The 545RFE name actually means a 4 speed, 5 torque rating, rear mounted, fully electronic trans with 5 forward gears pretty confusing. The 65RFE is just another computer program. If you take apart a 45RFE and a 65RFE the only difference is the valve body and trans pan.
Also since I've already gotten to take apart an 8 speed trans I can say they are pretty stout. There is only one part about them I don't like, there is an aluminum drum on the out side of the gear train that transfers all the torque coming into the trans to a rear gear set. It brought back memories of the old chevy 700r4 sun shell. But since the company (ZF) that makes the 8 speed has been using it for more than ten years in European cars they've already been tested. The 8 speed will change the game for chrysler, Its an awesome trans, and it doesn't eat up 60-70 hp like the 65RFE does.
The ZF 8 speed isn't a CVT and it will be a great transmission....
If it is good enough for Bentley, BMW, Jaguar and Maserati...all use ZF 8 speeds.....with more HP and close to the weight of a Ram.....I think an R/T truck with one would be great!
I would kill for a 8 speed with 3.21 gears.....
Acceleration of the 545 with 4.56 gears and the fuel economy of a truck with 3.21s
It might just be me but i saw a white 2013 r/t at a car show and im just not digging the sideways fogs and cheap looking projector headlights. Im partial to my 4th gen i guess
I'm holding on the 8 speed as well, I'll wait for it!, i just wish they put the air suspension on r/t but tuned for sport handling . that'd be the day!, or make a ram srt8!, Also I'm plannign mods already!
might want to ask your dealer i just called mine he said they are not putting the 8 speed and 3.92's in the r/t only the sport they are keeping it the 6 speed and 4.10's not sure why but thats what he said
