I'm new to this forum, and I've been searching and couldn't find the exact answer to my question. I was performing my first diff oil change. On the front, I drained the diff just fine, and I opened the check plug just fine. However, I missed a very critical part of the instructions for filling it back up -- instead of using the fill port on the passenger side, I used the nearly identical port exactly opposite on the drivers side (slightly above the axle). I realize now this is wrong. :frown2:
After doing some reading here, it sounds like what I did was add diff oil into my CVT. Can someone confirm if that is in fact where that port goes?
If so, my next question is this (and this is what I cannot find the answer to): does that port fill directly into the CVT pan (so if I drain the pan, will all of the diff oil that I added by mistake come out)? Or does that port fill into some other chamber in the CVT where it won't readily or easily drain back out?
My hope is that I can just drain the CVT, then follow the proper refill procedure for the CVT and it will be fine. But if that fill port goes into some magic black hole in the CVT, I'm worried the diff oil I added by mistake is hidden in there somewhere and won't drain back out. I have not started the car at all yet.
Guess who just made the same mistake? I've never had a Subaru before this one, although I've serviced and repaired many and varied things since I was a boy (now 60) rarely have I come across such a stupid arrangement as this. Subaru went to all the trouble of casting into the housing just where the drain and check holes are for the front diff, but not so the filler. The correct fill hole is not the obvious one above (leading to the transmission and unmarked) but one well hidden on the opposite side (also unmarked). Such a faulty logic, as draining something by mistake doesn't have the same consequences as adding something to the wrong compartment. The responsible persons at Subaru ought to be taken around the back and summarily executed.
I now have a couple of litres or so of diff oil in the transmission. A couple of litres, why so much? Because that's how far I got before I realised something wasn't right. But the manual specifies only about 1.2 litres! Well my manual also specifies 42 psi pressure for the tyres, but the placard on the vehicle says 32 psi. "If they can't get that right, what else have they got wrong", was in the back of my mind; not suspected the trap that Subaru had set for the mere mortals.
Anyway, I've found a few videos on flushing the CVT, and no doubt they are perfectly adequate for simply removing as much of the old (but correct) fluid as possible, but I can't find any definitive answer to the question of how to remove all the fluid in an economical manner. I've already cycled through some fifteen litres of new fluid, after draining the pan, and I'm still not confident with the result. Does anyone know of a more economical way?
