For some time the ZF-8 was to be in MY 2013 WK2 units. Now it's MY 2013 1/2. Will they really change transmissions mid-year when MY 2014 is likely to be a major upgrade?
Maybe, but this is starting to smell like vaporware for the near term.
Also iffy is this from that same article:
Chrysler’s SEC filing revealed that the company will launch engine stop-start technology in the U.S. soon. The European-market Jeep Wrangler diesel already has such a system; by 2017, Chrysler says 90 percent of its U.S.-market vehicles will be equipped with engine stop-start.
Just hope it can be user-disabled!
UPDATE: Elsewhere, it has just been reliably indicated that the 8-speed won't be in the MY 2013 WK2 (sigh).
