hey guys, my mom purchased this lesabre about a year ago i suppose. low miles, under 80k. After it warms up and you have driven it for a while, the transmission will clunk shifting gears. rpms seem kinda high too. Anybody know a solution? transmission fluid has been changed. Does not do this when you first start it, takes maybe an hour or so.
