Anything special about the internal trans filter in these subaru autos, or is it just the standard drop pan drop filter and replace? I see the trans (carfax report) was serviced at 77K, so I figured time to do it again. (155K)
I don't need to hear anyone's hog wash about servicing high mileage transmissions will result in failure... Just the Facts about the job
The internal "filter" is just a screen. It's probably fine, but otherwise, you just need to get it out and backwash it in a parts cleaner. No need to replace it unless you had major transmission issues....in which case you have bigger issues then replacing the screen.
I got the external filter also. Like the whole kit for $14 instead of $70 for just the filter. Since it's probably never been done I'll probably just drop the pan anyways and replace the filter.
Got the external one and internal one changed today. Biggest PITA of the internal one was that metal pipe that runs across the filter. I got it out. It's weird the pipe isn't press fit, nor does it have an o-ring to seal the pipe in place. It just pretty much sits in the holes and is bolted in place. I would think maybe it has an oring as I've seen similiar setups used for fuel lines, but the parts catalog showed no o-rings, and none were found on the tube, in the trans or on the floor.
Someone was right that a lot of trans fluid comes out of the one side of the metal pipe near the filter neck.
After draining, replacing both filters, and then refilling and flushing, and refilling I used 12 quarts of fluid.
The putty knife did the trick and I was able to get the gasket off with that, sandpaper, and liberal amounts of mineral spirits. Pretty cool how they use the magnet in there like the diffs.
Yes, you'll need a new gasket - I got mine for only a few bucks. I followed my lines and wasn't able to find an external filter either. The lines went straight from the trans to the radiator and back. FYI I have a '93 LS.
my 92 4EAT has the external filter. Maybe mine was a retrofit, but I thought someone said on here 92 on all had them. IF you have it, it's by the driver's side valve cover.
You can buy the retrofit kit for $14 that comes with the filter, bracket, lines, and everything. The filter itself is $70!
So I hit a snag with the filter change...there is a pipe running underneath the filter. When I pull down on the filter to take it out, I'm hitting the pipe before the neck of the filter clears so it's stuck in there.
you need to unbolt that pipe. it's two bolts. Pull straight down on the pipe, it will come out. There are no orings on the pipe. It just sits in the holes and is bolted in place. A LOT OF trans fluid will come out of the hole for the pipe nearest the filter neck.
If you've still got yours torn apart, does trans fluid slowly weep? out of the one pipe end closest to the trans filter neck? I noticed after I bolted mine back together, it seemed to weep a little bit. I don't recall if it did it before I unbolted it, so I was just curious if it does..
Thanks. Like I said I'm not sure if it did it or not before I removed it, but don't see why it would be a complete seal in the first place because the pipe just fits up in the hole.
Oh dear god that was a lot of fluid that came out when I pulled the tube...
Before I pulled the tube out I looked and there was a very small bit of fluid around it that was seeping out. Not dripping or anything, just barely seeping.
