transmission flush - will those flush machine do the trick? - PeachParts Mercedes-Benz Forum

The reason it is so important to change the filter on an auto tranny is b/c there is constant wearing of the clutch paks and the aluminum sliding parts ..and where do you suppose these worn off debris wind up ??? .. in the filter.
The suction guys will tell you it winds up suspended in the fliud ..it does..and then the fluid just carries it to the filter.
When changing a trans fliud/filter, I open up the old filters so I can get a look at the clutch debris and aluminum wear content..this gives an insight to tranny wear ..if you ever opened one up, you would see why you want to change it..new fluid can not go through an old filter any better than the old fluid could..a blocked filter restricts oil flow and that is the last thing you want happening inside your trans..you are better off with a new filter and the old fluid than you are with new fluid trying to go through an old clogged filter...
Change them both and clean out the pan while you have it off...they can agitate all they want, they don't get the crud out of the corners of the pan like you can with it off. Do it right..trannies biggest problems are DIRT caused !!!

The filter used on most if all trannys are merely just screens.
I've seen a pic of a 722.6 filter cut open with 130K that was pretty spotless.

If pretty much any transmission filter gets clogged the tranny is pretty much screwed!

Wrong..Benz uses mostly fibre element filters

..and I have seen hundreds that were not..which is why Benz Maint/Tech specs that they be changed. No pictures, just real time filter from the car...

Yup. That is why we change them....so they don't get to that point.

The fiber mesh MB uses is about as effective as a screen(over a 100 micron filter).

Tranny filters are very free flowing(they need to be),if a filter gets clogged it ain't debris it's the tranny in pieces.Screwed!
