Sounds like the fluid is just working its way through the clutch packs. I would give it a tank of gas and see if there is any improvement. If not I would take it back to the dealer and see if they will do another fluid change as they may have not gotten all the "brown" stuff out. I wouldn't demand it or anything, but they may do it because the fluid update was just performed and is not functioning 100% correctly. If this whole ordeal doesn't fix the issue perfectly, I would hate to say it, but it might need a gearbox(worst case tho!). Let me know and good luck!
