trans fluid

o2 3.0 12v u vin. I want to change trans fluid and filter. Does anyone know how many quarts I should buy? I'm just gonna drop pan and replace filter no power flush.Also is the u vin all that is needed to get right filter or do you need another number off the trans? Thank you for your help

Is the exact car I have. I just furnish the model and engine code at the auto parts store and have always received the correct filter. Have always used a Fram filter.
I use up most of 8 qts filling it up after a drain and fill.
One tip: Let the car down level before starting your refill. First time I did it I had it lifted in front and half my filling was overflowing.
