Question is.....I recently acquired an 8/05 production C 350 with the auto, and it has some jerky shifts, moreso than on my old 722.6. Was the newer-style (3353?) fluid used from the factory in this trans from inception? Also, I am wondering about the best way to approach my SA about it. Am I likely to get an early fluid/filter change under warranty, TCM flash, or what? Can't find much info in here on the 722.9, suppose because they're still in the warranty period and not many DIYers posting here about them
