Thanks guys! I am really happy to say that I got a complete system suck/flush and brand new Mercon w/additive for $60.00!!! I was really nice to the guys at the shop and treated them as fellow humans, and so, well they gave me a $30.00 discount! From now on I will def. do the 4 quart drain/fill.

The car seems to shift MUCH smoother now, it's odd. When I turn off overdrive, there is no longer the slight jerky feeling as it dips down a gear. I'm impressed. And my fluid was REALLY dark.
