transmission filter replacement

sullione · Post by **sullione** » Thu Jul 22, 2004 9:22 pm

I just ordered the tranny filter that goes on the side of the engine. I will replace it this weekend but need a little help. The kit that I got came with quite a few hoses whereas I thought it would be just a filter. One hose is rather large and I'm not sure exactly where it goes. Can someone help me out and tell me where this thing belongs? I can't seem to find anything in my Haynes manual about this filter. That may be because I'm missing a few pages...gotta love my kids.

The external filter, it's pretty straight forward. You knopw where the old one is right? Right by the driver's side valve cover. Just follow the hoses and you can replace it pretty easily.

Will I lose alot of ATF fluid when I swap this filter out. I did look and it doesn't seem that it will be too bad to replace. I think I will have to remove the engine coolant overflow bottle though.

you shouldnt have to remove anyhing really to replace it, it has a snap lock type dealy like the fuel filter, just open that, and it has more than enough room to swing up and around and all that so you can reach it easily. You shouldnt lose toomuch fluid but go ahead and check it once you're done and fill as needed.

Thanks for the info. but one more question. Should I go ahead and replace the hoses with the ones that came with it or just reuse what's already there?

i'd replace the hoses, it might be a pain in the butt right now, and not needed, but for the extra peace of mind why not do it? Also if you do repalce the hoses with it, you can get the filter in line with the tohers ones while out of the car, then just undo two of the clamps and put it straight in

Hmm, I never thought about that. Thanks THAWA. Makes alot more sense that way.

Funny, this thread. It's so appropriately timed.
I went to the stealership yesterday to pick up a replacement external filter (my tranny has been having some minor sound related issues over the last 3-4 months so I've decided to do whatever maintainence I can short of taking it somewhere), which btw, I found out has no service interval. I can't understand why, though. I mean, it's a filter. Filter media clogs and, as a result, becomes less efficient at filtering contaminates... *boggle*
Anyway, I got the filter (part no#38325AA032: ATF filter assy), but it's a screw on filter. I haven't pulled apart the assembly in the engine bay, but from cursory examinations, the screw on filter doesn't appear to be compatable with the one in the car.
Did I get the right part? Maybe the assembly comes apart and you can screw the filter into the upper part of the assembly (with the hoses)?
I dunno, I figured I'd ask here first, before I went all the way back to the dealer.
On a side note, I've decided that the Haynes manual is only good for reading on the john or as kindling. Anyone know where I can locate a
real shop manual? I'd be willing to pay the, surely, hefty sum (it'd be worth it for me).
Okay, that's it for me. I'm out.

The filter you got I believe is for newer 4eats. They have a place where you spin it on on the side of the tranny. About the real manual your best bet is getting a factory service manual. Subaruparts.com has em, they pop up on ebay everyonce in a while aswell.

I think I'll invest in one of the factory service manuals in the near future. It's funny because it took me longer to swap out this filter than it took to swap out the knock sensor.

Yesterday we installed this external atf filter kit.
Now the transmission slips when accelerating from standstill after a redlight (appears not when accelerating directly after stopping - you have to wait a minute or so). Also there is this 'brittling' noise - maybe the oil pump in the transmission?! I double checked the fluid level. To me it appears that the external filter restricts the oil flow to the tranny too much. Radiator is fairly new (so not clogged up) and filter is installed the right way 'round. Hoses not bend in sharp angles. Anyone an idea?

I drove my car last night after the install and loved every minute of it. I had no slippage whatsoever. When I floored it, it actually got up pretty quick and the transmission didn't miss a beat. I'll drive it again a little later to see how it performs in the hot air since last night's test drive took place a little before midnight.

Hmm, just replaced the external filter with a straight hose as it was before. But the noise and slippage persists. This is really strange. We did also clean the at filter in the oil pan besides there wasn't much to clean. We didn't flush the tranny only replaced the oil that came out when removing the pan. Anything I could have overlooked so far?

THAWA · Post by **THAWA** » Sat Jul 24, 2004 8:42 pm

yep, you're not supposed to service the internal tranny filter. It is manufactured to last the lifetime of the tranny. That's most likely why you've got slippage and noise.

bren_bjf · Post by **bren_bjf** » Sat Jul 24, 2004 8:59 pm

Yeah, clear to me. Besides it did not need any servicing

. But literally unscrewing it and putting it back into place can't make such a difference in driving. I don't like the idea to remove the oil pan once more and look if I can find something that I messed up the first time. Nevertheless thanks for your input.

honestly it shouldn't but who knows why it does/did. Yet another mystery of the 4eat

On a completely unrelated note, would you happen to know of a set of 89-91 headlights in your area for sale?

Sorry if I'm being annoying.

bren_bjf · Post by **bren_bjf** » Sat Jul 24, 2004 9:23 pm

If finding subaru parts in Germany would be that easy! Over here you have a hard time finding driveaxles, that seem to be traded in each gas station in the US...

Sorry, but I don't know of any headlights. Belief me, if I could find a car for parts it would be sitting in my backyard by now. I keep you posted however.

Another question: How long (if actually) does it take the torque converter to drain back into the oil pan, when the car is sitting with engine off under normal circumstances? Is this a matter of minutes or would it take, say overnight to get a way false reading on the dipstick? Yes I know, I have to check while car running and in P after going through all positions

Honestly I dont know. I was under the impression the fluid didnt drain out of the converter but had to be pumped through it. But I could, and probably am wrong.

i went to my local parts store, and then handed me a huge flat looking thing that goes up in the tranny fluid pan. it says i have to drop the pan, and slide this one in.

what gives? is this the internal one you guys are talking about? i didn't see an external filter anywhere

THAWA · Post by **THAWA** » Sat Jul 31, 2004 3:52 pm

I believe that's a dealer only filter as it is an add-on kit that was released after the cars were produced.

i gotcha. i'll call the dealer this week, and see if they might know what's wrong with this thing then
