It isn't necessarly the trans. Could be a bad wheel bearing or something, anything creating artificial resistance while it's moving.
 
I say wheel bearings because those are a common failure at that high mileage.

The dealer said he replaced the back ones. i guess maybe the front ones should be done next?

They can inspect the front to see if they're bad. There would be some "play" in the wheels.

ok, so i was driving my new-used 2007 Subaru outback 2.5i a good deal this past weekend and tried to localize whatever is going on with it a bit more. I had the ATF changed at the Subaru dealer here in asheville but the problem is still occurring. it seems to occur most at higher speeds (between 60-70 mph) and not necessarily during a shift but more when i'm changing speeds. and it feels like i'm driving over one of those strips along the road meant to wake you up if you fall asleep. it only lasts about a second and goes away. it also seems to happen more during inclines. oh and the ball bearings are all fine. any ideas?

That's a mystery because I would have guess wheel bearings next, and you say those are OK.
 
I would look at the front diff fluid and the rear diff fluid. Maybe drain and fill, and check the magnetic drain plug to see if any metal shavings came off. Basically looking for other symptoms.
 
Can you tell from which side of the car the noise is coming? Try to narrow it down to front vs. back, or the side.

Is there anything loose under the car that could touch the drive shaft? exhaust pipe, muffler heat shield? Also anything that could touch a wheel...brake line, etc.
 
Could it be the cooling fan or something driven by the serpentine belt?

are the diff fluids easy to change by yourself?
it actually doesn't make a sound really, it just feels like i'm going over one of those strips along the side of the road and i would say it feels like it's coming from the front, but i'll try to localize it a bit more.

I'll check this, but i don't think so. and it doesn't happen all the time, just those times mentioned.
 
there are zero rattles or shakes anywhere in the car that i can hear. i hate when things rattle or squeak so i'm pretty quick to act when i do hear something.

No real sound, but you can feel it and it only happens when the gears shift. Perhaps I am way off base here, but I almost think there is an issue with the torque converter - perhaps the lock-up clutch? It would be an uncommon failure if this is the case, but it just seems like it has something to do with the operation of the transmission.

it doesn't actually just happen when the gears shift, just when i change speeds. could that be the problem if it's occurring at times it's not shifting? most shifts are good, it seems that it only happens when i'm rapidly speeding up. like if i was going up an incline on the highway and have to floor it (since it's the 2.5) to keep a constant speed, it'll happen. then after it does it, it might shift and some times it happens a couple times in a row.
 
Sorry if it's confusing, i really dont know much about cars and i don't want to go into the dealer to get them to check it out without having some idea. they will charge me a bunch of hours to figure it out.
