First time and trying to figure it out however, I just want to say thanks for the great information. I have saved $ DIY. Thanks to all of you I have replaced the trans. filter and gasket, the O2 sensor, the idle air control valve, brakes, and fixed the door handle spring! Now the problems I have are replacing the front engine mounts, an axcel boot, oil leaks, ac\heater blower fan, and car alarm. This is a 97 Tl 2.5 with over 200K. Great car.
