Cool trans improvement and mileage

I noticed before, my mileage average for my driving style, I get 28 mpg city and 38 mpg highway. I am a spirited driver. I just wanted to share, I have flushed my transmission (around 71k miles), first time per records (I bought the car at 68k). While driving before the flush, I thought it shifted just fine. I didn't like the way the fluid looked, it looked about mid quality, and thought a flush would do it good. I underestimated. I notice now, it shifts seamlessly. I can almost guarantee I get better mileage, and will report back my averages. I typically do not go far (it may take a month), but will report back the mileage gains, if any. Based on how much better it shifts (went from good to great), I predict I get at least a 1 mpg gain. Just wanted to share so as to help in the quest of great mileage. Me, coming off a 94 Caprice wagon (15 city/23 highway which is fantastic for that big of a car, by the way), I am still in the ecstatic with what I have phase, knowing some of you are getting 50 mpg. I flushed with a graduated bucket, and stock WS fluid, 8 quarts, then a half a quart to top off from spillage.
