Default My sad story

Last night I was driving and went through a bit of a pothole. As I entered where my wheel was getting air, my engine revved up, and then I heard a loud metal clunk...never a good sign. I am unable to stay in gear as I hear a noise ALMOST similar to a dying clutch, except I think it's the transmission. My engine is shaking a lot at idle, which now shakes the car. And I can't really get past 2nd gear til the issue becomes much worse. I need advice my NASIOC brethren, what is it? Is it my tranny? Can I just buy a used one? Is it possibly my rear differential? How do I check without going to a shop? Sorry if I should've posted in the noob section...


To make matters even worse...........brace yourselves.......I have to drive my parents Prius til I get it fixed

Thanks,
Chris

Can't get past 2nd gear
Are you driving an Automatic? Or you mean that while shifting up the gears, it isn't that bad in 1st, gets a little worse in 2nd, and is god awful in 3rd and up?

Also, define "a bit of a pothole" Did you go in enough to damage an axle/knuckle, suspension part?
I'm a bit confused why your engine would have revved up with just one wheel in the air over the pothole. The other 3 wheels should not have allowed that.

Well, I punched in my clutch then let off it as I entered the hole. I guess you could call it an accidental "launch"? I'm sure it has to be my tranny or diff/:

That all sounds really unusual. I can't really imagine what type of transmission or differential damage would cause a shake at an idle. When you say it 'revved up', did you nail redline with it? Any CEL codes?

Maybe a broken motor or transmission mount? That would certainly cause a loud metallic clunk, some weird noises and vibration and make it difficult to shift. Just throwing that out there off the top of my head.

Can you maybe post a video of the noise you're hearing?

Do you have a good shop you take it to? Do you do all your own work? Obviously, something is wrong. You should limit the amount of driving and get it in to a shop to have it diagnosed.

You're getting way ahead of yourself here. The way I see it, you have two options.

1. Get the car on a lift and find out if anything is damaged. Suspension, transmission, etc. If you're not comfortable with doing this yourself or don't have the resources, go to option 2.

2. Get the car to a Subaru specialist and have that specialist examine the car. That will cost money. If you don't have money to have a specialist examine/repair the car, go to option 1.

Could be a motor mount, could be a tranny mount, could be a lot of things. If you can't put the car on jack stands to find out, tow her to a good subie tech. Diagnostics aren't expensive.

This may sound silly, but is it possible it's just an alignment or wheel issue? If a big chunk of pothole got in the wheel it could cause it to go off balance and the car would shake very badly at 45-50mph.

At idle what happens when you push in the clutch?

Need more info, but it sounds like your clutch disc broke.

I got just two CEL codes. They were P0102 and P0113

P0102- MAF or VAF A Circuit Low Imput

P0113- IAT Sensor 1 Circuit High Input

These two codes were also repeated with a "Pd" at the end, if that means anything. Yes my engine shakes a lot at idle and causes my car to. I could post a quick video of it, do you think that I should risk hurting it more for the sake of a video though? *not trying to be sarcastic

Keep the suggestions coming please. Hopefully it's just a mount.../:

Sounds like you're intercooler dislodged, check all your intake hoses

Bad idle can mean something as small as an 02 sensor... and also a MAF sensor as bob pointed out. Where did you hear the cluck, right or left side?

Would that explain the grinding metal sound? It seems like its my tranny. It also grinds a little as I'm in neutral.

Just changed my Diff fluid, and it seemed fine. I'm guessing its the tranny

Any idea on pricing of a new tranny?/:

Stop. You have no idea what is wrong with your car.

Start listening to our advice and take it to someone who knows what they're doing. Those two CELs have abso****inglutely nothing to do with your transmission.

If you legitimately hit a pot hole and it caused this much damage you can submit an insurance claim and just pay your deductible....

worst thing you can do is ask random people on a Subaru forum to diagnose your car
