NorthWet Posted August 16, 2006 Share Posted August 16, 2006 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.

lmdew Posted August 16, 2006 Share Posted August 16, 2006 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 Link to comment Share on other sites More sharing options...
Jerry DeMoss Posted August 16, 2006 Share Posted August 16, 2006 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.

nipper Posted August 16, 2006 Share Posted August 16, 2006 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 Link to comment Share on other sites More sharing options...
NorthWet Posted August 16, 2006 Share Posted August 16, 2006 ...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! Link to comment Share on other sites More sharing options...

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!!

johnceggleston Posted August 17, 2006 Share Posted August 17, 2006 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. Link to comment Share on other sites More sharing options...
skizix Posted August 17, 2006 Share Posted August 17, 2006 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! Link to comment Share on other sites More sharing options...
