2000 RX300 AWD transmission ceased engagement in forward and reverse. When started cold I could get it to move a little. Repair shop says "the valve body won't hold pressure". I have noticed other posts suggesting cleaning the filter might help get some more miles out of the car. The car is not worth the price of a rebuilt transmission but if I can coax a little more life out of it by a simple cleaning I will. I really like the car but for the price of a rebuilt trans I can upgrade to a newer model.
