Well, I just dropped the pan and replaced the filter and gasket. By the way the filter was not a wire mesh and the tranny was supplied by Lexus. There was very little fuzz on the magnets, that is good. I also changed the external tranny filter that I installed previously. The fluid drain was still a little black, but still red in color. These RX300 AWD just don't seem be friendly to the fluid. The fluid was only 7.5k old. and the transmisson is only 15k old. Well this was the last thing I wanted to do on the tranny this year. Next I get to replace the right front shock upper strut mount for a second time and the fluids in the differential to synthetics. Merry Christmas and Happy New Year to all and God Bless our Troops overseas.
