Default Changing 4eat and Diff fluid

I'm gonna change my 4eat and rear diff fluid within a week or so with synthetic and was wondering if there was anything I should look out for. Seems like a simple task, but sometimes simple tasks can turn out to be a pain in the arse when done the first time. Anyone have any tips?

Thanks,
Ed

Ed,

It's not too hard to do. Make sure you have a crush washer for the tranny drain plug. Change the front diff oil while you are under there changing the rest.

One more thing, make sure to take the fill plug out of the rear diff BEFORE you pull the drain plug. If you drain that diff & then find you can't remove the fill plug you are well & truly screwed.

If you plan on changing the filter screen inside the transmission, then that can be a pita the first time you do it. You have to remove a couple different tubes to get it out. The tubes are what makes it hard.
I don't know how you plan on getting all the old oil out. The transmission hold around 15-20 quarts of oil. When you drain the pan you only get out about 8 quarts. So that means you would be mixing fluid and only doing about a half job.
I would take it to a oil change place that has an oil flusher that hooks up to the oil lines. I don't know if they can put your oil in this way as they usually draw it from a 50 gallon barell. Also, get them to flush out your radiator cooler too. This is done by a flusher machine that uses solvent.
Also this would be a great time to add a real transmission cooler and filter if you don't have them. You can pick up a filter kit from subaru that has EVERYTHING you need for something cheap like 13 bux. Yeah, 13 bucks gets you everything you need to install an external filter right under your battery in the car.

this is the tube you need to remove to get access to the screen. They usually don't get gunked up unless the trans has problems.....then you really should do more then just change the fluid.

The two arrows point to the bolts that hold it in.

Thanks for the great tips and pictures guys. Does the tranny really hold 20 quarts? According to the manual, the capacity is about 10. Is it not like draining engine oil that I can get most of it out without flushing?

4EAT. I would just do a drain-fill. No need to do the filter unless you are having problems or if it's like 100K miles.

When you do a drain-fill you will get out about 4.5-5quarts out of the 10 in there. What I usually do on the race car that I daily drove as well, I changed it out every 20K miles and you will eventually get all of it out.

What synthetic are you using? My favorite so far has been Redline HighTemp ATF.

I could be wrong on the total number of quarts in there. I know with my truck it's something pretty similar to this (yeah i know the wrx isn't a truck ).
If you're going to the trouble of changing the fluid why do it half A$$ed? True, if you don't have many miles you can probably get away with not changing the filter. I don't think i've ever even seen anything in any of the screens that i've changed/cleaned out. You can clean them out too. So you don't have to buy a new one either.
But, there will always be crap in the magnets that are worth dropping the pan to clean. Not to mention this in itself will tell you a lot about your tranny and how it's holding up.
What you could do is this: Drop the pan, clean the magnets and the filter screen. Change the atf then drive it a coulpe hundred miles and then just drian and refill (as you will have a clean pan/screen etc..) and that would work better.
Good luck.

actually the 4EAT is a truck based transmission....believe it or not. It's undergone some tweaking by subaru for the AWD system. But the base 4EAT has been used in quite a few different cars/trucks

Stand next to the right front fender & look down. See where the axle comes into the tranny? It's just above there on the top of the tranny. The dip stick has a yellow handle. If you still can't see it take off the air filter box. It really isn't too easy to see.
