August 16, 200619 yr I have owned very few auto tranny subarus. What is the best way to flush the tranny of my brothers roo? Is it best to drain and add, then repeat? Or is there another(better) way?
August 16, 200619 yr what i did was drain and fill , poured it into jugs then i knew how much i drained out , do this, drive it a few thousand miles and do it again
August 16, 200619 yr Service facilities offer a "power flush" which will change all of the fluid at once. It is pricey (around $60-70) and I have heard (on USMB) that they might not do this for Soobs. I do the "change and repeat" myself, but that is because I am cheap.
August 16, 200619 yr I drain and fill and then pull the return hose off the radiator. Run a hose into a gallon jug and start the engine. Pour fluid in the trans at the same rate its coming out into the jug. When you have clean fluid coming out the radiator cooler, you have flushed the trans. It takes about 3 gallons for a complete flush. Check out www.bossproductsusa.com for a great trans filter. Larry
August 16, 200619 yr Unless you are going to do a power flush like above described I would recomend using the specific seafoam stuff for auto transmissions before you change your fluid.Gets rid of deposites and varnish ect.
August 16, 200619 yr Two methods, power fliush (fine for subarus, i dont know where people hear these things sometimes that it is not). Second is drain fill drive around the block repeat 3x's nipper
August 16, 200619 yr ...power fliush (fine for subarus, i dont know where people hear these things sometimes that it is not)... A member mentioned that they had been told that it couldn't be done (at a Jiffy Lube-type place) and I haven't read anything from someone who has had it done. I am assuming that you have had it done, so now we know!

I am assuming that you have had it done, so now we know! The reason you do not want a jiffy lube or cheap place to do it is they use cheap machines that push way to much pressure through your tranny and can damage it. I rear shop uses the cars own tranny pump to flush it. I would never let the morons at jiffy lube even check my spare tires air pressure, let alone change oil or flush a tranny!!

I was quated(Tuffy Service Center) a price of $140.00 to power flush my Forester, moreover, this included a new filter. John

August 17, 200619 yr Not sure about that; my 2000 OBW has an external filter on the automatic transmission.
August 17, 200619 yr Not sure about that; my 2000 OBW has an external filter on the automatic transmission. Mine has an external Spin- on type filter. they cost about $25.00 John
August 17, 200619 yr a local quick lube place would not flush out my 88 turbo a/t wagon , so had to do it myelf
August 17, 200619 yr ... no "filter" as soobys dont have filters, just a screen that is good for the life of the tranny. nipper Newer 4EATs (mid-90-ish?) have spin-on external filters.
August 17, 200619 yr 99s were the first year to have spin on filters, and i think that was a mid year change. filter trans model numbers ended in xxxxx"zjeba" or something like that. Newer 4EATs (mid-90-ish?) have spin-on external filters.
August 17, 200619 yr For what it's worth (possibly not much -- I've never owned an AT equipped car)...I've always heard that a power flush is a huge can of worms, and can F up your AT in a big way, especially if it's high mileage. Something to do with contaminating low-tolerance parts with metal filings/sludge. A good friend had his AT go irreparably south immediately after a power flush (Ford Taurus though...). Best to do the passive drain and replace, perhaps a couple times in a row -- at least from what I've heard. However, nipper's knowledge/experience surely trumps my own, so take my advice with a grain or two of salt. YMMV!
