ShrinerMonkey Posted August 18, 2011 Share Posted August 18, 2011 I'm not sure you can either... however when I did fluid changes on my 2007 2.5i with the 4eat, I seem to recall only changing the rear differential fluid and the ATF, which is shared between the tranny and the front differential. Aside from that, the only other fluids that were changed were brake fluid, coolant and oil. I don't recall it needing to change anything else. The transmission fluid in the 4EAT is NOT shared with the front differential, they are separate. The front and rear diffs use gear oil and the 4EAT uses ATF.

whiteknight24 Posted August 15, 2014 Share Posted August 15, 2014 Now I'm confused. I have a 4EAT tranny. (09 legacy 2.5i) I was under the impression (from other threads) that both the diffs and transmission fluid were the same, and I could use the same fluid. I was planning on using redline 75w-90 fluid. Now I'm reading that I need to buy separate transmission fluid and diff fluid. Please clarify.

Wheelbuilder_25 Posted August 15, 2014 Share Posted August 15, 2014 The 4EAT does indeed have separate transmission and differential fluid. You will need both. The 09 also calls for Subaru's HP transmission fluid, due to different friction materials. I've only seen it from Subaru, no third parties. You should be fine with the redline for the differential.

whiteknight24 Posted August 22, 2014 Share Posted August 22, 2014 Can I use Super tech 75w-90 syn-blend for the transmission fluid? Link to comment Share on other sites More sharing options...
apexi Posted August 23, 2014 Share Posted August 23, 2014 No, anything 75w-90 will be a gear oil which you can only use in your front or rear differential. You need to use Subaru ATF-HP or something comparable in your transmission. Link to comment Share on other sites More sharing options...
Wheelbuilder_25 Posted August 25, 2014 Share Posted August 25, 2014 IIRC, the 09 and newer 4EAT (and the 5EAT too) need the ATF-HP from Subaru or Idemitsu equal. Supposedly there was a chance in friction materials in the tranny, and Dexron doesn't behave correctly in them. As far as the diffs, any GL-5 is OK. Some like Subaru Extra-S, but as long as it's a GL-5, you should be good. Link to comment Share on other sites More sharing options...
GEE-OTTO Posted August 26, 2014 Author Share Posted August 26, 2014 Can I use Super tech 75w-90 syn-blend for the transmission fluid? I used SuperTech for 45K miles no issues great low cost fluid that works well in in the cold. Link to comment Share on other sites More sharing options...
whiteknight24 Posted August 26, 2014 Share Posted August 26, 2014 Will Royal Purple Max ATF #01320 high performance multi-spec synthetic fluid work for my auto tranny? Link to comment Share on other sites More sharing options...
GEE-OTTO Posted August 26, 2014 Author Share Posted August 26, 2014 Will Royal Purple Max ATF #01320 high performance multi-spec synthetic fluid work for my auto tranny? If that meets the book spec you can try it but Subaru ATF HD is plenty if it tames the 5EAT its good on your 4EAT:) No need to pay extra for that gearbox Link to comment Share on other sites More sharing options...
anthonyr Posted November 9, 2014 Share Posted November 9, 2014 Anyone ever use Lucas oil 75 90 In there front and rear diff Link to comment Share on other sites More sharing options...
Wheelbuilder_25 Posted November 12, 2014 Share Posted November 12, 2014 The Lucas oil should work OK, but from what I've read at bobistheoilguy.com, there are better gear oils for the same money. Link to comment Share on other sites More sharing options...
DonnyJagaru Posted November 18, 2014 Share Posted November 18, 2014 Thanks for the write up. I changed mine and put in conventional 80W90 and it worked fine. Link to comment Share on other sites More sharing options...
htioki Posted October 3, 2015 Share Posted October 3, 2015 I couldn't get the T70 bolt out. It's on there tightly, even with a cheater bar it didn't budge. Any suggestions on how to get it out? Link to comment Share on other sites More sharing options...
apexi Posted October 3, 2015 Share Posted October 3, 2015 Mine is usually pretty tough to remove every time. I usually have to use a breaker bar, and it eventually comes free. Link to comment Share on other sites More sharing options...
soloz2 Posted October 3, 2015 Share Posted October 3, 2015 it's pretty tough to get out, but just keep at it with a breaker bar and eventually it'll come.

soloz2 Posted October 5, 2015 Share Posted October 5, 2015 Glad to hear! It's one of those things that is easier said than done and it's not something you really want to get an impact on if you can avoid it.

DonnyJagaru Posted October 5, 2015 Share Posted October 5, 2015 Mine was stiff too so I used the impact gun. Unfortunately it didn't slow down quickly enough and I got a tool and hand full of old tranny fluid. Just wanted to add that a trick I used to fill was to place a hose into the filler hole and put a funnel on the end. This worked fine. Link to comment Share on other sites More sharing options...
cluesblues Posted October 7, 2015 Share Posted October 7, 2015 Used this tutorial not too long ago for my last service. Needed a breaker bar and a cheater pipe to get the T70 plug but otherwise it's a cinch. Also found there was no need to unbolt that bracket with the wires on it, especially if you have a funnel that's even a little bit flexible.
