I have a decel gear noise that is pretty loud.
But I don't care! To me it sounds normal for AWD.
Even though this is the 1st AWD car I've owned I am a tech
and if someone came to me, I'd say it's normal.
Plus who wants to have their car all torn apart when they haven't pinned down the cause, etc. If it's a problem they will figure it out and in the long run you'll be better off because they will be able to fix it efficiently.

 

What if it's a progressing problem that gets worse and worse and you drive it, until it gets so bad one day, your tranny just becomes shot? We would like to say it's normal for now, since we don't know exactly what causes it. Let's say down the road, you ignore that potential problem and mod your car, when Mitsubishi finally acknowledges it. You take it in and they say that due to your mods, they will not service you. Will you still brush it off then?

 

The noise is irregular! That's not normal to me.

 

I took my car into the dealership and had the shop foreman drive with me. He indicated the first gear whine was normal, because of the heavier duty gearing. Next we listened to the buzzing decel sound at around 3k in 2nd and 3rd gears. He indicated that sounds normal. He mentioned if the sound changes or gets louder to bring it back in. Also we listened to the clangy noise when shifting into 1/2nd after engaging the clutch. He indicated that was the syncro gear matching to the engine speed. I had it documented so it was in their records and I took a hard copy.

 

Thats not exactly correct. I'm one of the few that have had a tranny replaced (mine was done at 700 miles). THe tranny was not replaced due to the decel noise, it was replaced because they had a manufacturing issue with the machineing process, in that the shavings were not being fully cleaned from the tranny housing before assembly. My tranny was replaced because they found enough metal shavings in the tranny fluid for them to feel mine was one of those affected by the manufacturing problem.

The official position on the decel noise (told to me by the southeast regional parts/service manager) is that the noise is "normal" and "inherant to all evo's". Based on this. mitsubishi does not consider this to be a problem. At best you can get your dealer to put in a PQR with engineering and wait for a tsb to come out.

Having said that, the more folks complain to mitsu about the noise the more likely they are to find a fix. With the S2000's the issue was addresed by tsb 054 changing the design of the clutch disk. Though the noise, actually a mechinical vibration, comes from the back faces of the gears in the tranny the clutch springs may be picking up and amplifying the vibration to create a more apparent noise as was the case with the S2000.

So if the noise bothers you, as it does me, go see your dealer and ask them to put in a PQR (prduct quality request) with mitsubishi about the decel noise. You can reference honda tsb 054 for the s2000. Just do a search for "honda s2000 tsb 054" on yahoo and you will find a pdf copy of the tsb.

 

I've ridden in two S4's and one A4 Quatro, none of them made the decel noise that my evo makes.

Not saying it's a problem, as I don't think there is a risk of mechanical failure, just anoying as hell from time to time.

 

Hello all,
I had the same sound decribed over and over throughout this forum. I had it looked at by the Mitsu service dept. Turns out it was the throw-out bearing in the clutch. They replaced it and now ... no sound! I hope this may help.

 

I have just noticed this same noise on 3rd and 4th gear deceleration down to abouit 2500rpm. I am getting very mixed responses from everyone taht posts here. But the noise is bothersome enough for me so I am taking it to a dealer anyways.

This just ruined my long weekend and to top it all off, I just discovered that all my tires were at around 49-51 psi!!!!!!!!!!!!!!!! No wonder the ride was so rough. Only 450 miles so far, so I guess no biggy. But how could this have happened? The sales guy assured me I was getting a pre-sale inspection done to the car and I would assume tire pressure should've been on the fricking list!

 

Were the tires hot when you checked em? They probbly set them to 45. For what it's worth I run 32.5 front and 30 rear cold pressure. You should get an alignment done asap. Mine was way off and I was able to get them to fix it under warranty, but I still had to pay the alignment shop to do the first one and find out how far off it was.

 

Did you listen to the mp3 clip I posted a while back on the tranny failure thread?? If your noise was like mine I would like to pursue the T.O. bearing with my dealer. Did your dealer ever open a techline case on your car? If so can you PM me the techline case # So I can reference that.

 

Tires were at ambient temp. I made them give me their word that they would do an allignment before I picked up the car. THe salesman said allignment is standard procedure before any sales pick-up. But now, with the way they handled my tire pressure, I'm not too sure I can trust them. Anyway you can tell if you got bad allignment without going to a shop? Anything else besides seeing if the car would pull to left or right when steering wheel is let go?

 

Mine didn't pull at all, but it would breakloose a lot easier turning left than right. My right front camber was +.4 left front was -1.6. They may have screwed it up when they did the tranny swap, since I'm fairly sure they dropped the subframe for that and I didn't have the first alignment till after the swap.

They SHOULD do an alignment on every new car, but I know they didn't do one on mine cause it took them a month to get the specs from mitsubishi and get the alignment machine programed for the evo AFTER I brought up the issue.

Make sure they give you a print out of the numbers or at least show them to you on the machines screen. But as far as them doing a pre sales alignment on every car... not likely at all, just sales BS.

 

Talked to another dealership about my decel noise. The Service Rep did a ride along and heard the noise and he was concerned enough that I have an all day appointment scheduled for next week. I will keep you guys posted. Seems like it is louder now...750 miles. Appears to be between 2500-3000 RPMS in 2/3/4 gears. I agree with you guys now, it sounds like a throw-out bearing.

 

I have had the same sound in Neutral and when i push in the clutch it goes away.And on all gears with a louder but same sound on deceleration. I took it to the dealership and they started a file report on my car with the Mitsu tech line. My master tech said it did notsound good and has replaced 3 trannys her in Atlanta Ga and mine sounds worse than all of them but since it is not slipping they told me it is normal to sound like a Coffe grinder on Deceleration and not to worry about it. OK...... And if it gets louder bring the car back. Basically the tech wanted to go in to see what could be the problem but Mitsubishi said nope......and his hands where tied.
I just hope I dont end up on the side of the road or without my Evo for a couple of weeks!

 

Which dealer are you dealing with?? Peachtree? Mall of georgia??

My tranny was one of the three (it was done at peachtree) Limey was the first, he live up in north georgia not sure what dealer he went to though.

Like I said in another post.. the biggest problem we have right now is the fact that the techline engineers keep telling the dealerships that everything is "normal"

I'm not sure how techline works, but it seems the dealers have to open cases with them before they can do any repairs.

I think it's time to start doing some reasearch on mitsu japan, I remember reading about them getting busted for denying warranty repairs not too long ago.
