Transmission FILTER replacement

[razdog]

2003 Lexus LX470
At what millage intervals should the AT FILTER be changed??

Since its your first post I just want to clarify that the LC/LX has a filter in the pan on the fluid pickup tube, not an external filter. Id call it a screen rather than a filter.. It doesn't really filter the oil, just makes sure chunks and other debris doesn't go in the pickup tube. It is not a regular maintenance item that needs to be replaced. If you had 300k on the original then I'd replace. Otherwise people just usually put a new one in if they drop the pan for some reason.

Thanks. So, are you telling me my car has NO AT filter at all?
All I need to do is have the fluid flushed with the machine?
The filter in the pan has been changed before.

Yes no filter. Just that screen in the pan. Just do a fluid flush the way outlined on this forum.

Last weekend, I changed transmission fluid drain and fill only. Easier than changing engine oil.

What is the difference between Toyota T-IV transmission fluid and Toyota AFT-WS?

This will be opening the potential for massive transmission failure. The chemicals used in those machines to flush a transmission aren't kind to the seals and o rings inside of the transmission.

If you search around here there are detailed instructions for doing a drain and refill without using a flush machine.

Thanks for all the info. I have watched the AT fluid changed on my Ford F250 using a machine and they put new fluid in one reservior and pumped it thru and catching old fluid in another reservior. Would this service be called a FLUSH or just an EXCHANGE?

Check previous post #7.

FLUSH=EXCHANGE=FLUSH

If you know how to change oil, you can drain and fill the ATF. If you are doing it yourself, consider buying fluids on trusted Ebay site. You can buy 1/2 dealer price.

With a true "flush" they have cleaners that are cycled through the transmission via the machine.

A fluid exchange is using the same, or a similar machine, to simply pump all of the old fluid out and refill it with fresh fluid simultaneously.

A drain and fill usually refers to only draining via the pan and refilling. This only replaces a portion of the fluid.
