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

Interesting. Makes getting the Pentastar instead of the Hemi a bit more attractive for us non-SRT types.

After ordering the HEMI I was disapointed to fing out it was not the W5A580.

I did a little digging and found out that the the W5A580 transmission has a torque capacity of 796 lb-ft, while the 545RFE has a torque capacity of 500 lb-ft.

545RFE is awesome with the new TSB. Does not feel one bit like it has any deadspots in need of another gear. High RPM small engines are the main reason for so many gears these days because of their narrow power band, very little nead IMHO for them with the Hemi, think back to transmissions in 60's muscle cars.

Back in those days of three notches, four at best, and few OHCs a main concern was the redline, usually limited by rocker float. I suspect ten gears and the resulting narrowband operation is going to get boring pretty fast.

Just for the people that are interested it looks like the CRD GC comes with the "DGJ-5-Speed Auto W5A580 Transmission" as well, so it is only the Hemi that does not have this gearbox.
