How has the 8 speed transmission held up to being mated to the HEMI on other platforms? I remember seeing some teething problems with the 8 speed on the SXT's.
It's a ZF transmisson but Chrysler is calling it the TorqueFlite to "cash in again on the nostalgia with a fortuitous name change". It said it right there in the paragraph.i'm really confused with the 8 speed trans whether zf or not. What do you guys make of this paragraph from this site?

Not getting lost in the shuffle is the addition of ZF’s new 8HP70 8-speed transmission, which it shares with the Chrysler 300C and Dodge Charger for 2015. Christened the TorqueFlite 8-Speed in the Challenger, marketing types hope to cash in again on the nostalgia with a fortuitous name change. For those not in the mood to shift their own gears through the massively robust standard TR-6060 6-speed manual (which now offers a dual-disc clutch for lighter effort and more holding force), the paddle-shifted 8-speed TorqueFlite is said to offer better fuel economy and performance, though EPA mileage figures are still pending. When asked if the 8-speed trans in combination with cylinder deactivation on the 392 HEMI would produce EPA numbers good enough to skirt the $1,000 gas guzzler tax, our Dodge contact said “it’s going to be tight—we’re right on the line.”

Oh ok, i didn't read that far into it.It's a ZF transmisson but Chrysler is calling it the TorqueFlite to "cash in again on the nostalgia with a fortuitous name change". It said it right there in the paragraph.
"TorqueFlite (also seen as Torqueflite) is the trademarked name of Chrysler Corporation's automatic transmissions, starting with the three-speed unit introduced late in the 1956 model year as a successor to Chrysler's two-speed PowerFlite. In the 1990s, the TorqueFlite name was dropped in favor of alphanumeric designations, although the latest ZF-based pickup truck 8-speed automatic has revived the name."

The TorqueFlite name is just that, a name that is trademarked by Chrysler.
Yup....Chrysler built or retrofitted a plant at Kokamo Ind. to build the ZF under license. Two versions based on torque specifications.Its the same 8 speed trans going in all the mopars which are using the 8 speeds...

That's just plain sweet. You get the benefit of 3.92 gearing, and your rpms at 80mph are lower than that of a 5-speed Charger with 3.06 gearing. 80 mph in 5th in my SRT, I believe that's about 2,200 to 2,300 rpms.Oh and it's nice to be going 80 mph down the highway with 3.92 gearing and my rpm's are at only 2k.
I saw a predicted mpg of 18 city and 27 highway for the 8-speed Hemi. That's not official, but if the 8-speed 3.6L is 18/31, I could see more like 17/29 for the Hemi.I know it's early but I hope Dodge publishes MPG for all models including R/T Road and Track. The reason is with the difference in gear ratios between the models there is going to be a MPG difference, correct? I remember reading for the Blacktop package that had the 3.06 gears Dodge stated in their brochures that the lower gearing did effect MPG but never gave numbers.
There is no way the V6 and V8 will have the same city rating of 18. I guess we could hope for 17 city at best.I saw a predicted mpg of 18 city and 27 highway for the 8-speed Hemi. That's not official, but if the 8-speed 3.6L is 18/31, I could see more like 17/29 for the Hemi.
I think the Pentastar is actually 19/31, not 18. Still agree with your estimate of 17 though.There is no way the V6 and V8 will have the same city rating of 18. I guess we could hope for 17 city at best.
I'm hoping that was a misprint. They pulled it from the updated media stat sheets.I think the Pentastar is actually 19/31, not 18. Still agree with your estimate of 17 though.
Incidentally, does anyone know why the city mileage for the R/T decreased from 16 to 15 for the 2014 MY?
huh? There is no MPG rating for the 5.7 on that sheet. All the EPA testing and such hasn't been completed so there is no official number yet.I'm hoping that was a misprint. They pulled it from the updated media stat sheets.

I was actually referring to the 2014 (not 2015) R/T, which is rated at 15/25 instead of the 16/25 for 2011-2013 models. Not really related to this thread, but it's still a little odd.Correct there is no mpg stated on that sheet that I posted. On the original sheet that was released, it stated that the R/T got the same MPG as the 14MY (maybe a +/- 1MPG). The sheet that I posted is the most current sheet, I hope.
I was referring to what Chops had posted, I saw the same estimated MPG that he saw. I saw it on the original spec sheet
