Default dccd failure update Matt seriuos!!

Dealer said the center diff along with transmission is shot,also some electronic
parts.Subaru gave me a loaner and will be
up from Jersy to verify before replacement
of parts take place.They were suppose to
be here Today,now maybe tuesday.The mechanics,service manager are 100% sure
on the diagnosis.I had to paperwork out of the car it was in the back torn apart,center
console etc,mechanic(nice guy,liked the car,felt my pain,fellow wrx owner) showed me how they k now by manuals and this electronic equipment that was on the dash with wires going to the dccd dial and to the center diff.( he said when this happens they
do not mess around any farther they tear out the whole tranny with center diff for a full
replacement.Better for me and easy for them.He said it will take 4 to 5 hours once
they verify it,and he gets the parts.This is all I can really tell you guys right now,I will try to more info after things are ordered and I can talk to this mechanic again,maybe after he fixes it and has it torn out ,He will have more about what happened and why or maybe it was just
a failure of the center diff.Matt

You've gotta be kidding. Do you know anything about the STi 6 speed? It's a beefy box. I've got a picture of the innards right here on my desk.

This simply sounds like a clear case of dead on arrival(DOA). This happens even w/ the best electronics and this sounds to me like an electronic failure.

The fact that you mention dead electronic components interests me. If they perhaps were defective, controlling the center dif, couldn't that quickly subject the rest of the transmission to a load that far exceeds what the transmission components would see in a state of normal operation?

This doesn't necessarily sound like a weak tranny at all. If the center differential isn't operating correctly, you could quickly tear apart the strongest of transmissions with even very little power, I would think.

Maybe the vallet dude who got sent out to fill it up with gas after it was PDI has something to do with it...

...perhaps a "refurbished" press release car??

I would bet the transmission is just fine. The STi 6 speed is a serious piece of engineering. The center diff and transmission are a single integrated unit. They probably just decided to replace the whole thing then try to figure out how to locate the exact problem and fix it. I bet that tranny/diff will get shipped back to Subaru USA and a mob of engineers will tear the thing apart to find out exactly what went wrong.

I think you are correct,The car drove to the dealer fine,shifted just like day one,clutch in and out fine,no shutter or different release
feeling,also when cold it was quiet.Friday,the mechanic first stated he thinks it is electrical.
When the car sat overnight and in the morning after it was first started it would go 20 to 30 miles then it went into failure mode.At first they thought I was crazy and told me it was fine,I said take it for a long ride and you will see what I am talking about.Sure enougfh he went 25 miles before it went into failure.My father is or I should say was a car designer and now collecter and has some good connections(also pretty mechanical,races an audi 5000cs turbo quattro up giants despair and in denver) his
opinion on the matter was it is integrated electronic center diff.,the brain for controlling the diff is usually the problem.Alot guys with 100,000 in wrx"s are all using the new 6 speed wrx sti trannsmissions once you get the brain diff tranny working there bullet proof.Also can handle 500 ft lb of torque while beeing abused.You bought good stuff,better to find out now then later,just a fluke in the electronics.Matt

I agree.
The ECU is the weakest/most vulnerable link and per Occam's Razor its the most logical reason for the trans problem.

I'll bet they pulled the entire trans unit though as mentioned earlier to allow a staff of propeller heads to investgate the entire problem and all possible variables for future knowledge & prevention.

The 6 speed mechanicals & DCCD itself are proven to be Tonka tough.

Just like how the Evolutions tranny can handle 600+hp?
