Hi, this is my first post here.
I have a 2011 Forester with auto trans. I plan to change all the fluids. The transfer case has a Torx or star type drain plug. Do you guys know what socket I need for this, and where to get one?
Also, What type of oil do I use for the diffs, and transfer case, and trans? Do I need to use synthetic?
If you get an aluminum washer for the front plug, the torque is in the low 30 ft-lbs, and if its the copper washer its around 51 ft-lbs or so. You can find the exact numbers in another thread. The AT plug is around 18 ft-lbs, also searchable in another thread.
Look around for the rear diff plugs and you'll see there are many torques recommended as well, and some people like to use sealant, some don't. I believe ADC recently said he uses 22 ft-lbs. If it works for him, its good enough for anyone.
The AT uses Subaru type HP.
The thing about doing a drain and fill on the AT, and this was very kindly pointed out to me by another member is that there appears to be a special computer controlled purge cycle required after the fluid is replaced.
He referenced the procedure in the service manual, and I found it in my own manual as well. What I'm not clear on is if it pertains to a drain and fill or is only applicable for a full fluid exchange.
Anyone know? I may start a separate thread as more 09 and later owners may want to start doing a drain and fill on theri AT.
