I am all for DIY, except for when it comes to circulating 16 quarts of fluid through your trans. You are bound to make a mess, it will take some time, and you will have a lot of oil to transport to a recycling facility. I had this procedure done with Mobil 1 ATF and it cost $40 for the exchange (plus the cost of ATF which I purchased from Autozone). Money well spent in my opinion. As for cleaning the screen, there has been mixed opinion as to whether this needs to be done at all. I don't believe Toyota suggests a service interval for the screen. I drain my trans pan along with my motor oil every 5K miles (about 5 quarts of ATF in my 2002 4Runner) per the suggestion of someone on this board. Fluid Looks nice and red always and I am a bit hard on my trans (towing and living in a area surrounded by mountain passes).

Should you clean the screen, please report what you find. Anyone else clean the screen on an 01-02 with 50K or so? What'd you see? <img src="/forums/images/graemlins/cheers.gif" alt="" />
