Improve shift speed of automatic
What options are out there to improve the shift speed of the automatic? I notice the shifts while not particularly mushy like some cars I've driven, they're still softer than I'd like even under full acceleration. I would like the shifts to be firm and quick. Sport mode seems like it's a bit better, but I'd like to do something that will get the automatic shifts to be as close to something like a DSG-style fast shift as is possible for this kind of automatic transmission.
How much of this is electronically controlled and how much of it would require actual modification of the transmission? I still have warranty that I'd rather not void. Do they still make shift kits for autos or is it all done with tuners now?
