true, under normal driving conditions, the metal mesh tranny filter does not need to be changed. it is just there to catch metal shaving so that they wont re-circulate with the fulid. there is no gauze or absorbent property to the filter so changing it wouldnt really do much for your tranny. if you have a lot of metal shavings resting on it, you should either stop driving the way you are or just flush it all out. very simpleblueMM said:i just called my dealer and they told me that the tranny filter is a stainless steel filter and does not need to be and is not recommended to be changed on all lexus vehicles. true or false?
