Transmission Service/Flush

[LugNut]

As in the link above states, don't have a trans force-"flushed". But replacing the filter, pan gasket, and the fluid that does drain out by gravity, and cleaning the pan, is fairly cheap and easy. And do only use true Toyota ATF-WS -- I think I needed 5 quarts to do mine.

My drain pan has a convenient OEM drain plug, so in a couple of years I'll likely drain it down again without changing the filter.

No difference in performance observed in my case; no chunks in my pan, just the normal light dusting of clutch material.

Like the link says, if the fluid is burned, you've got bigger problems. In my experience, changing the fluid and filter in such situations only makes the dying transmission shift/slip worse. Save up for a rebuild instead.
