"... When I take it in for the 60k, I'm going to request that the external tranny filter be replaced. I don't care if they say it's supposed to be a lifetime filter..."
That is only part of what the Service Schedule says. Footnote 9 says:
9. The ATF filter is a maintenance free part. The ATF filter needs replacement
only when it has physical damage or if the ATF has leaked.
One issue of Subaru's EndWrench publication says:
The transmission filter does not require service under normal conditions.
Another issue of EndWrench says:
The external oil filter requires no scheduled maintenance, although it can be changed if neces- sary. The new filter is in addition to the metal valve body screen found on previous models. The screen is still present and can be flushed...
"... there is no way that filter is supposed to remain free flowing for life. I'm sure there is clutch pack sludge buildup in the filter which will eventually restrict flow..."
If sludge buildup in the filter was a problem, then the filterless transmissions from 2008-on avoid it by distributing the sludge throughout the transmission. Which is a good reason for a BG flush by the dealer:
BG Quick Clean for Automatic Transmissions is a safe and effective solvent/dispersant cleaner that will quickly remove accumulated deposits from the valve body, filter screen and other automatic transmission components. This product is designed for use in the BG Power Flush and Fluid Exchange System.
The BG PF5 Power Flush and Fluid Exchange System dissolves and removes harmful deposits from... all internal transmission components including torque converter, valve body assemblies, lines and cooler vanes. and exchanges the old, oxidized ATF for new fluid...
I have not seen where Subaru recommends against flushing. My dealer flushes.

"... My closest servicing dealer said SOA advises against using a flusher but my mom's servicing dealer says they've never been told not to use this machine on a Subaru AT. Thoughts?"
My dealer pushes the flushes. The flushing machine is an expensive investment, and does take some training to use. Maybe some dealers don't want to offer that service and badmouth it.
It is unlikely that SOA would really tell some dealers it was OK and others that it was not.

I'm just going by what the closest dealer told me. I have 2 other dealers to chose from, both about an hour away, so I'm going to call them and see if they have a machine. If I can find someone to flush, then I won't worry about changing the filter out. Back when I was a Honda/Acura tech, we changed the ATF on those cars every 15k. I don't know about the new Honda products but the mid-90's models didn't have a filter at all, just a screen inside to catch the large particles, thus the reason to do a drain/fill every 15k. Drain plug was the magnetic type and I don't recall ever seeing one that didn't have some metallic sludge sticking to it.
#319 of 439 Extended warranty on HG leak?
Dec 19, 2009 (12:50 pm)
My son has an '02 Forester with just under 90k miles. He is losing coolant and I suspect the HG leak. Does SOA have a "policy" of extended warranty to cover the HG problem?

Some 02s were covered, others were not. That was the last model year.
But...you had to have gotten a letter from SoA and used the coolant conditioner at a dealer, then the warranty was extended for 7/100 IIRC.
You may be past the 7 years, though, and did they ever send you a letter?
Our 02 Legacy was not covered, then again it never had a problem, either.

"... If I can find someone to flush, then I won't worry about changing the filter out..."
If my 2008 had still had an ATF filter, I would want it changed with a flush. It would become filled with the crud that the solvent and flushing was removing.
"... when I was a Honda/Acura tech... the mid-90's models didn't have a filter at all, just a screen inside to catch the large particles, thus the reason to do a drain/fill every 15k..."
The Subaru 4EAT has always had an internal screen. The draining the ATF does not lift and remove material from the screen.

Not officially. I think it helps if the car was serviced at a Subaru dealer every 30 months or 30,000 mile with new Subaru coolant and Subaru sealant additive. If the old coolant was left in for 90K miles, or replaced with the wrong type of coolant, or the sealant additive not used, Subaru might not be as generous.
#323 of 439 04 xt forrester check eng lt, cps senor and misfire code
Jan 09, 2010 (10:00 am)
got crank positon sensor code as well as misfire on all cyls, does this mean I need a new cps sensor? runs great around town, but dont take it on a trip! Have been through two turbos and engine rebuild at dealer warrantee expense. Now off warrantee and have encountered these new codes. Would like to resolve before selling car. HELP!! When last to dealer they claim functioning to spec for $85 fee. Maybe cps sensor malfunctions due to sustained elevated temp? Car has never shown any overheating problems. Possible the turbo creates this on trips? I think that the turbo puts too much stress on this otherwise dependable engine. Othewise i love this car but I am being forced to sell due to reliability, dont ever buy a turbo! Four strikes and thats enough. any advise on the cps code would be appreciated.

We read it, but do not always reply - it depends on whether folks think they have something meaningful to contribute.
If you are getting a crank position sensor code in conjunction with misfires in all cylinders, there is a very good chance that is the problem. If that sensor (or the camshaft sensor) is not sending, the ignition coil is not going to fire at the correct time.
