Default Doing an AT fluid swap in a few days...do i NEED to change the filter?

Replacing my pink stuff with trickshift (thicker)...is it neccesary that I change the filter at the same time or can i wait until i pick one up? Also...since the trickshift is thicker will i run into issues using an OEM AT filter?

Also I assume I drain via the drain plug and refill via the tranny dipstick correct?

I recommend taking your car somewhere to have the tranny flushed. Just taking the plug out will only drain about half the fluid in the transmission. Fluid still remains in the torque converter and other places. With a flush it actually forces all of the fluid out as it refills it with new fluid. 100% new fluid. Subaru doesn't recommend replacing the filter on a normal tranny service. Only when damage has been done to the tranny and it needs to be rebuilt. I'm not sure how much fluid you will actually need to do a tranny flush, it's more than recommended though. But just a drain and refill takes about 4 qts and the actual tranny holds around 8 I think.

what if i force air into the dipstick/fill area with the plug off? I have special fluid im putting in (6qts) and while i dont mind mixing it with the old (which is actually pretty new and in good conidtion) I'd like to get as much out without doing a total flush.

Subaru uses FujiBond for their gaskets. Its a pinkish/red silicone type sealer. Dropping the pan will probably get 6 qts out of the transmission. I think when Subaru had the parking pawl recall you had to drop the pan and the solenoid body. They paid for 6 qts of fluid. If you take it to a place for a full transmission flush, tell them you have your own tranny fluid to put in it. They will probably do it.

Full flush: somewhere around 11-12 quarts
Drop pan: 6 quarts or so
Remove Drain Plug: 4 quarts

And you don't need to replace the filter. Might find more answers in the Transmission Forum as well.

Call your garage of choice and ask if they'll use your fluid. Is the new fluid compatible with the stock stuff?

I agree that if it's worth doing then it's worth doing right. WOuld you change 1/3-1/4 of your motor oil at a time? Probably not.

I read that it's "not recommended" to change the filter, but I'd probably do it anyhow.
