Does anyone know what is going on with the transmission oil when it is brown in color? I just bought this car and my experience with transmission oil is supposed to be reddish color. I talked with transmission shops and it was mixed reviews to change it or to leave it since it is "life time" on the oil. Lexus will not say anything until I bring it in but I do not want to get raped on charges just for them to look at it.
