Oh..... but this is all very confusing.
 
Here was your first account of the situation: but now when i'm driving most shifts feel perfect but every so often it feel like i ran over a speed bump when there is nothing there. it happens a lot on the highways and in the mountains but doesn't necessarily happen every time it shifts or for a certain gear but seems to happen most when i'm accelerating or decelerating. Any ideas?
 
We have now moved past the "speed bump" scenario (which I must say is quite different) to rumble strips. But, still no sound, just a feel.
 
I must say it seems like engine hesitation, with all things considered. Do you know the maintenance history of the vehicle? Is this the one that was a dealer demo (I get my stories confused)? This may be something as simple as worn spark plugs, but without knowing if they were replaced yet, it is hard to say. Also, no codes in the system would likely steer away from that theory as well.
 
*sigh*

to make it even more interesting, i think it's doing both now. but it was first feeling like i hit a speed hump but after resetting the computer and getting ATF changed, now it's doing the rumble strips with a few speed bumps thrown in there (though they could be the same thing, i may just be paying more attention some times) and again neither of these happen all the time or very often and almost never during city driving.
 
Nope, no service records. its an 07 with 80k miles on it. i know i should just take the thing in to a dealer, but i really don't want to spend too much on the diagnosing part of it as it's $90 an hour. If there are no engine lights on, would it make any sense to hook a reader up to it? i have access to one if it would help at all.

Hi all, newbie on edmonds. im a gm tech but it does sound like torque convrter clutch. try driving steady at 50 mph for a bit and just touch brake pedal enough to light the brake lights but not enough to slow the vehicle and the tcc should release and when you let off brake the tcc should lock up again. if this what we call "shudder" returns on re apply then your problem is torque converter. hope this helps

so i tried that last night and it didn't really do it. do you all think it could be a spark plug missing?

spark plugs by ashevilleian

So i think the last cheap thing i can do to fix whatever is happening with my subaru is change the spark plugs. My friend and i are going to do it and have found the correct plugs. Does anyone know what the torque should be for them? again, it's a 2007 subaru outback 2.5i.
 
Thanks

well, new spark plugs are in and the problem is still there so it's most likely the torque converter...sounds expensive

Transmission filter by jasondpf

I have a 1998 Subaru Legacy outback, and I recently changed the transmission fluid, and filter... unfortunately for me, it now will not drive at all!!!
 
I called a mechanic and he says I should have just cleaned the filter in place, and not removed it. Does anyone know how I can fix this!? my car is stuck up on ramps and wont drive.
 
I was sure that all the electrical connections were still pluged in when I put the pan back on.
 
Please HELP!

So what is not working? Is the transmission just not engaging when you select a gear?
 
First off... make sure you put enough fluid in it! If the fluid is very low, it will not build the hydraulic pressure needed to engage the gears. If the level shows fine, it may be that something is not aligned properly on the filter and the fluid is not able to flow through it as it should.

Clattering, binding, high torque on an auto AWD trans 106k 97 Outback by pangeus

1 year ago the trans started binding during tight turns. I adjusted my driving to avoid sharp turns. The engine/trans would also have a lot of torque when I put it into park to turn it off, and would lurch backward once that torque was shut off. I applied the brake before shutting it off so that lurch would not occur. I operated under hope that the trans would decline linearly over time rather than fail all at once.
 
So when I took it in recently I had them replace front axles and CV boots, valve cover gaskets, crankshaft seal and timing belt. Now that these new parts were on, an intermittent clattering noise began to come from the trans. If I start it up, the engine is fine and has all power. Acceleration is fine and smooth. There's no bucking. There is still the old binding problem and high torque while in park. The mechanic mentioned something about having too high a pressure in the trans, and that it was throwing a code.
 
I drove it slowly a few times and the intermittent loud clatter eventually 'spun' and settled down into a light, constant clatter coming from the trans.
 
1) Is it possible that the front axles which went bad were over-stressed by the binding problem?
2) Is it possible that the valve cover gaskets and crakshaft seals were worn out and leaking due to some over pressure caused by the trans?
3) If I baby it on level, low-speed, A-to-B streets, do I have a good hope the trans will last a while longer?
 
Repairing my own trans is quoted at $1800 minimum, so I'm wondering about a junkyard replacement trans.
 
4) What year and model range of Subaru trans will work on a 97 Outback AWD? Any horror stories about a junkyard trans replacement turning out to be crap?
 
Thank you!
