I haven't heard anything from the Evo I've driven (it competed in the One Lap of America) or from the recording which suggest a problem with the transmission. Remember, even though this car is new to the US, it has been around for some time. I also have not heard of fragility issues from the boys that have been and are rallying these cars. It sounds like many folks are simply being paranoid.

Also, didn't you test drive a car before you bought it? You have 3 days after purchasing a vehicle to take it back and ask for a refund - no questions asked.

It is a good car with a proven drive train. If you are worried about something in the drivetrain, I would be concerned about the center differential.

I agree that the car has been around for years, but is there something different in the drivetrain of the US version?

As for the test drive, the sound that people are hearing, if like mine, starts at around 800 + miles on the car.

I picked my EVO up with 12 miles on the odo monday night. I just heard the clip and my car is making the same exact noise. I'm glad I'm not the only one. The began to notice the noise yesterday at the 300 mile mark. But I have a feeling this has been going on since mile 1. Its just the hype feeling started to wear down just a bit.

I've babied my car since picking it up. Most of my miles have been highway. I have not gone over 5k rpm yet. In fact I've been averaging about 23mpg city and highway.

I personally think its a bad bearing somewhere in the clutch assembly. I had a 5.0 mustang years ago and it made the same exact noise as my EVO tranny. I sold it 2yrs later with the same noise. Never got it looked at.

If anyone is willing to try..

I also can notice the noise at idle believe it or not. Find a quiet area, roll up your windows and turn the radio off. Listen very carefully to any change in sound between having your clutched depressed and not. I can notice a slight change in tone. With the clutch out...I can hear the clutch spinning and whining/rattling a bit.

My old mustang did the same exact thing.

My WRX had the same thing, it was the clutch assembly. I am hoping it is the same for the Evo and not the tranny..

EXACTLY!! I tried the same thing. I rev the car without the clutch depressed and I can hear the rattling in the tranny. When I step on the clutch and rev the engine, no sound at all. Sounds to me like a bad throwout bearing or something.

I started a thread about the rattling sound, when the clutch is NOT engaged. Claudius told me its pretty much normal for the engine and transmission to make a different sound when the clutch is NOT engaged, when you engage the clutch the sound goes away.

I took mine to the dealer and they said it was normal, but I didnt tell them about the 5000-3000 rpm whine.... I get the SAME grinding sound while at idle, that I do when decelerating from 5000-3000 sounds like some kind of grinding, and is a little louder than my WRX.
if you are watching tell the Auburn, Washington dealership to take a better look at things with their EVO customers! I hope I too dont have a defective tranny!

Oh BTW - the WRX fix was installing a HEAVIER flywheel so the drivetrain was loaded at all times, which actually hindered performance...

Well. I got the car back today. Still has the same decel noise though it does not seem to be as bad as it was. Funny thing is this time they clearly stated to me that they did find metal shavings in the tranny fluid when I took it in last week, that is even printed on the invoice. I say funny because when I asked them last week they said they did not find any shavings. I unfortunetly did not mark my casing before i took the car in for the replacement though it does look like they did something under the car and some of the factory paint marks are broken.

I just don't know what to do at this point. I love my evo, but I cannot stand that damn decel noise. and my first payment is not due till the 26th.

Mitsubishi says all the evos do it but I think ricardon would agree that if all of them did it, a lot more people would be going back to the dealer with complaints.

I say if they all do it, let me drive everyone on the lot and prove it to me, not just "the blue one" that they "drove and it did the same thing".

I thought it was just my imagination but I thought I noticed that as well a few dyas ago. It was more pronounced with the ac on though.

I actually kind of think we are all just paranoid (except for the few that found CHUNKS in their fluid) because my WRX made just the same sound as the EVO, and it never EVER gave me any issues whatsoever. The noise on mine isnt really that bad, just i guess, another characteristic of the AWD drivetrain. Until something snaps, im gonna mob this **** out of it after the 600 miles break in.... (mobbing the ****' while still keeping it reasonable of course!!)

I just hope your right!

Ok i retract my previous statement

As I venture further into the RPM range I find the deceleration noise to be worse and very much more apparent. From 4200rpm down to about 2800rpm. I havent taken the engine anywhere near 5000rpm yet as I currently have 240 miles on the car.

Although I did do a test:
There is this steep hill up my valley road, so I smashed up it in 4th gear, keeping RPMS at about 3500-3800, mind you this hill is a little steep but when I let off the accelerator, i did not get any decel noise. This must be because the drivetrain was loaded..? Just like the WRX clutch setup fix, a heavier flywheel and pressure plate were incorporated to fix this...

What do the JAP spec and EURO spec evo's sound like? Anyone... Cladius?

I think you guys would be afraid to drive down to the corner store in my car with the noises it makes.

EVO SPECIALIST

TimK #1 it depends on the state,don't go tellng people that,that could cost you a very big law suit by the dealer and the the buyer.#2The evo's drive train is heavy duty,but just a little abuse lke any other very high performance car and you can **** the car for life.

ShapeGSX

Deceleration rumbling can be any number of things that are not the transmission. In DSMs, the number one cause of deceleration rumble is worn-out driveshaft mounts.

I don't think that your cars have worn-out driveshaft mounts. It is just an example of a sound being something other than your worst fear.

The sound may be 100% normal in an Evo.

If the left rear wheel fell off of every evo everytime you turn on the right blinker that behaviour would be %100 normal as well. That wouldn't make it right though now would it.

All I can say is that if every evo sold had the exact same noise that mine does the dealer would be seeing a very high complaint rate. I simply refuse to believe that all evo's have the same noise that mine and at least a few of the folks that have spoken up so far seem to have. I have owned plenty of vehicles, granted this is my first awd car.

I don't care if it is a $10 dollar heat shield or a $3000 gear box or a $500 clutch that is causing the noise, I want it fixed and it should not be up to me figure out what the problem is. If they let me drive every evo on every lot here in georgia and they all sound the same as mine I might shut up. But it would be a lot easier for them to just fix my damn car. As it stands I have not riden in or driven any evo other than my own. I went to the dealer with the assumption that it could be tranny related based on the original post from limey about it sounding like a heatshield vibration. I asked then to check the tranny fluid. Mitsubishi is the one that decided to replace the tranny not me.

The recording I posted does not clearly illustrate the sound as it was made on a portable mp3 player from inside the cabin with the built in pinhole mic. Just trust me when I say everyone that rides in my car says "what the hell is that" when they hear it.
