Well folks I am very happy for all of you, I too have had a very quiet year, but my maintenance schedule is very detailed and the transmission ( third one) still exhibits the turning of color to black. I have added a transmission filter (external) and cleaned and drained it three times in the last 16k miles since the last tranny change. My only other maintenance has been fixing the stuff Roseville Lexus messed up. Other than that I enjoy driving the car, but just have bad vibes, like some others on this forum. We are trying to make it go another 100k, but time will tell. I am going to add a tranny cooling fan on the Aux cooler this spring. Maybe it will help the summer commutes that my wife does in stop and go trafffic. Best of luck to all AWD RX300 owners this 2006.....
