car sluggish after transmission fluid flush/refill

[ottawag35]

Just had my 2006 g35 serviced at the Infiniti dealer - they changed the diff fluid and flushed/changed the transmission fluid but now the car seems to have lost a little bit of snap- is this common or does it take soem time for the new fluid to "break in" ? the shifting is excellent as always still.

It would have to be sluggish as in the engine is pushing as before, but there is more resistance in the driveline. If the engine feels like it's running weaker, find out if they did ANYTHING more than change the fluids.
