99 Leggie OBW w/ AT, tranny filter question

[Rooster2]

How many trany filters does it have? I know there is an external spin on filter, is there also an internal filter under the pan? I am reluctant to drop the pan just to look. I have also heard dropping the pan encourgages leaks upon reassembly. Any advise??

 

I did a "search," but couldn't find answers. Thanks for any help

do not replace the internal "filter". it's not even a filter, it's just a screen and they do not get clogged or restricted (i mean i guess they could if your transmission flew apart internally but i'm assuming that's not the case here!) i have replaced them in the past before i finally figured this out.

Thanks for the advise. I dropped the trany pan on a 91 Leggie, when I had that car. I agree with you. It was simply a fine mesh screen wire that hadn't trapped hardly anything in 100K+ miles. If Subaru still uses the screen, then I won't bother with it.

 

My car has the external AT filter that looks just like the oil filter. It appears to be the original with 160 K miles on it. Maybe, I should replace that one?

Doesn't affect me, but I've often wondered: Why would a manufacturer add a "spin-on external filter" unless it was meant to be changed periodically?

i would change the external filters based on mileage and time...it's nearly 10 years old. there's really no reason not too.
