No, unless it has significant debris ... which you cant know til you look. The strainercatches all the bigger debris that may be in the trans when its put together. After that its kinda useless and presents an added suction restriction. I removed mine at 1st oil change.I'm just going to wait until the first trans oil change. I have 500 hours and haven't cleaned this strainer yet. All my hydraulics work fine. I've done the filters on schedule. Is there any reason that it must be cleaned now?
