many have
Many forum members have replaced their standard automatic transmission fluid (ATF) with synthetics and are very satisfied. I considered it when I added my transmission cooler and remote filter. However, after doing that my ATF runs very cool and I don't think switching to synthetic is worth the cost. The Mercon V is already semi-synthetic. If your ATF temperature runs high due to no external cooler, towing or off-road then I think switching to full synthetic is worth the cost. If I lived in a very cold area (I used to live in North Dakota) I would switch to full synthetic for its better flow at low temperatures.

I live in Syracuse, NY so the flow factor in winter would help me, although like you said it would be expensive. I think I also have a cooler. The fluid flows in and out of the bottom of the radiator via 2 hoses. I was curious if the transmission shifted any smoother using synthetics. My 03 X used the Mercon V, but my '06 uses Mercon....I'm not sure if it's partly synthetic or not. I'll have to look into that. Thanks.
