JulianH Posted December 30, 2015 Share Posted December 30, 2015 I've seen a lot of mention of a seal that prevents ATF from getting into the differential and killing it, but no mention of where this seal lives, and what it's called. I'm swapping in a new (to me) tranny, and would like to get that taken care of while I've got it out so I don't have to worry about it. Any ideas where it is, how to get to it, what the part number might be, etc.? Quote Link to comment Share on other sites More sharing options...
porcupine73 Posted December 31, 2015 Share Posted December 31, 2015 Here we are she's a double lip seal: The part # and such you could probably find on parts.subaru.com Quote Link to comment Share on other sites More sharing options...
JulianH Posted December 31, 2015 Author Share Posted December 31, 2015 OK, so I have to pull the differential to get to it? Quote Link to comment Share on other sites More sharing options...
Fairtax4me Posted December 31, 2015 Share Posted December 31, 2015 Yep. Pretty sure the tailhousing has to be removed as well to remove the lock but on the end of the pinion shaft. Not very common for those seals to leak though. More common leak would be the o-rings on the tube that runs through the diff case that the converter pump drive runs through. The tube is shown in the first photo. Quote Link to comment Share on other sites More sharing options...
Caboobaroo Posted January 1, 2016 Share Posted January 1, 2016 Yes, in order to remove the pinion shaft from the transmission, the tailshaft housing has to be removed. Pan removal isn't required for this job but if it's seeping or leaking, now is a good time to reseal it. I also will replace the rubber o-ring on the wiring harness with the pan reseal. But I agree, probably the transfer tube is leaking. Quote Link to comment Share on other sites More sharing options...
