Tranny filters different from oil filters?

teambeechstreet · Mar 3, 2007

Hi guys, sorry bout the newb question. Didnt really know where to put this. My buddy has a 2002 Subaru Forester and he was changing the oil in it and mistaked the tranny filter as the oil filter. He pretty much destroyed the filter. No places around us carry a tranny filter for it and I was wondering if we could use an oil filter instead or are there huge differences in filtering media? thanks

Should not be a hue media change but you may want to get a proper one ASAP.

Looking at the WIX site, it "APPEARS" the only difference between the filters is length & diameter. The listed Tranny filter is smaller, but nominal micron rating is the same. It is also used as an oil filter in some other apps.
The only potential problem I see is clearance???? I don't know if that's an issue since I don't have a Forester to look at.

I agree with Bill. There's nothing exceptional about this filter. If he can fit the larger one ..then he can get away with carrying one filter for both.

thanks ya'all!

Luckily for you Subaru uses the same thread on the ATF and oil filters. You can use any of the variously sized 20mm threaded oil filters on that transmission. Pick one that fits and doesn't leak.

Wow thats wild.

I've never seen a transmission with a spin on transmission filter.

I've always dealt with fords and their pancake style filters.

Usually AT filters will have a higher PSI shell and have a more durable casing, so get the correct filter ASAP.

I'll agree with you in a generic sense ..but both of these filters are common passenger car filters. He need not concern himself with the differences.

Wix 51365. Both for oil and ATF on both my Subarae (isn't that the plural of Subaru?).

My 45FRE has both a pancake and spin on (return). The only problem is that the spin on is inside the pan.

That's why I recently added an external spin-on hydraulic filter.

thanks folks, we had called napa and they said they didnt have it in stock, but we lucked out and went in person the same day and they did have one in stock.

This will get you the general idea of how I did it (scroll down). Just have to find a place to mount it, and plumb it with hose to/from the tranny. I have mine right after the trans, before the radiator and cooler.

The hardest part was finding the room, and getting the OEM hoses off! What a pain!

I will update that thread with pics when I get some time and miles on the unit. Thanks Gary for the info...it made it possible.

Fish hook (like)hose barbs ...yes, a challenge of high aggravation

The problem is almost every material will shrink when expanded, so the more you pull on the hose, the tighter the connection becomes. It's much easier to get the hose off those type of connectors if you use a screwdriver at the end of the hose and pry it off. That way you're compressing the rubber and actually expanding it off the barb.

Hmmmm...I'll have to try that next time. This time I knew that I wasn't going to reuse the hose so I tried to just cut it off (along the axis, not accross)...and it was still major pain in the arse.

It's an acquired skill
