Thanks, mtofel1. The manual says to replace fluid and filter at 50,000 miles under normal driving conditions. I have 54,000. I've read posts on here before about the pros and cons and, like you, came away more confused than when I started. I figure if I call the dealer he's going to say, "Sure it needs it. C'mon in." :) I don't believe my manual says anything about flushing. I guess what I was hoping for was some real world experience from the forum. I'm certainly in no hurry to spend $200.00 + if it isn't absolutely necessary.
