outbkownr Posted March 8, 2005 Share Posted March 8, 2005 I am a new outback owner and did my first transmission fluid change and mistakenly added trans fluid into the front differential gear oil chamber. Will this break down the gear oil during driving or should I have this towed to a mechanic to have this gear oil changed out? 1 Quote Link to comment Share on other sites More sharing options...
NorthWet Posted March 8, 2005 Share Posted March 8, 2005 In general, ATF does not damage gear oil, and is often added by some people to either thin out gear oil or help clean things out (it is high detergent). I think that you could just drain the differential case well, refill and run for a while, and probably drain/refill again. Quote Link to comment Share on other sites More sharing options...
baccaruda Posted March 8, 2005 Share Posted March 8, 2005 yeah, you'll be just fine. i'd drain it overnight and refill it and never think twice. i once started to top off my car's oil with ATF (grabbed the wrong bottle), right in front of a friend. he's a gearhead too so we both just laughed at me.

Drain it out & put some new gear oil in. If you can't drain it yourself it won't hurt a thing to drive to the dealer or to the local oil change place & have it drained & refilled.

benebob Posted March 9, 2005 Share Posted March 9, 2005 How much did ya put in til it overflowed? You're fine changing it on your own if you did the ATF. The plug is in front of it. I think it takes like a 22mm or something weird like that. You should need like 2 quarts of dif oil. Quote Link to comment Share on other sites More sharing options...
