I have to agree with you on that, synthetic is a lot thinner at the cold start, however, our Xfires come with a synthetic ATF+4 which is only available thru DamilerChrysler.
What I was suggesting was a warm up period as the trans is only a part of the drive train which is cold. Your trans lub., rear end lub., clutch fluid, pressure plate splines and even shifter lub. are all effected in drivability when cold.
Up here in the frozen North, I have had cold starts in the -35 range and you can really freeze your Niblets. Could it still be mislabeled oil, with DC? Who knows!
No speed shifts here until it gets toasty!
