I'm surprised we have no further info on the 2012 6 speed auto

I figured being a few days out from the 2012 production that we would heard more official facts on the new 65RFE tranny for the HEMI. I've read a few things online that contradict each other. Hopefully, we will soon learn more about it since I ordered my new 2012 Overland with the HEMI and can't wait to take delivery. Hopefully, it helps with the performance aspect of it.

Anyone else here any new information on this tranny?

Re: I'm surprised we have no further info on the 2012 6 speed auto

Thats one of the things I read so basically its still the same tranny operating as the 5 speed in regular mode unless you use the AutoStick. Seems as if they are misleading us if thats the case. My hope was it was going to be a true 6 speed auto like the 68RFE with different ratios that would work for upshifts and downshifts. I guess I will soon find out once I take delivery or something official comes out in the coming weeks.

Re: I'm surprised we have no further info on the 2012 6 speed auto

Curious that yesterday's press reports on the 2012 SRT say that it will have five speeds, not six. There has to be a good reason for this, assuming the reports are correct.

The tranny is completely different in the SRT8.

That's as good a reason as any. Gotta wonder why, though -- can't handle the added torque?

The SRT8 WK2 uses the same Mercedes W5A580 transmission as the 3.6L WK2s. Why? I don't really know

It's a good transmission.
Best I have driven.
Reliable.
Has been used in heavy vans as well.
And luxury cars.
Proven
Smooth

And I believe it's still in use in most of the high HP AMG's. It's a proven box and the only reasonable replacement would be a dual clutch type auto/manual IMHO.
