Transmission failiure

Crankwalk is/was not isolated. The LOWEST estimates (by people on the web and my Mitsu dealer) put it at about 5%. It may well be higher, but even at 5% that is 1 out of 20 cars. That is far from isolated. If a major problem starts occurring over time, you can be assured that Mitsu will do nothing about it, as long as most cars make it past the warranty. That said, it is probably an isolated incident, I doubt many transmissions will self destruct after 1000 miles, but hey, what the heck do I know...

If 1st and 2nd gear are straight cut then they will whine. It also means that they are much stronger than a helical cut gear.
Whining is normal. Metal bits in the fluid is NOT!
This also is not normal:
That's my broken intermediate shaft. The gear in the foreground is 3rd gear.
This is a DSM tranny. I don't think that Evos have an intermediate shaft.

the metal bits in the fluid are the reason mitsu is taking my transmission apart - the tech that test drove my evo said that the sound coming from my trans was not the same as the other three in the dealership -

Funny, but the Supra may cost you more than an STi.

I drive an eclipse, and first gear is always pretty whiny. I drove an evo the other day and first gear sounds a lot like my eclipse. Once you shift to second it goes away just like my car.
Good luck limey......maybe they'll throw in a prototype ralliart evo 8 ecu and send you on your way.

Take this for what it is worth, but for those of you hearing a "deceleration" noise (different that normal whinning you hear in trannys) when you are coasting in a low gear (2 or 3) consider this:
The WRX clutch and flywheel on at least the 2002 models often made a strange, cyclic, rattling-grinding sound on deceleration (coasting- foot off of the throttle at around 2500-3000 rpm). Basically, without any load on the system, the clutch assembly was making this noise.
To test to see if this may be your clutch (not your transmission per se) get the noise to manifest itself and then press the clutch in. If it goes away, it may be the clutch or flywheel. Subrau replaced a bunch of clutch and flywheel assemblies because of this noise. The tranny worked fine (if you don't abuse it--lets not get off topic here) except for the noise, which was annoying.
Enough people were hearing this noise that SOA eventually developed a diagnostic process for it and I had mine replaced at about 20K miles, under warranty.
So, some of you may be hearing a similar decel noise that is not your new tranny ready to self destruct.
It sounds like Limey had a different problem with all that metal in the tranny fluid! Was the drain plug totally caked so that there were actually pieces in the fluid?!?

Yes, nice theory but if its in the EP80....it's trashed the cogs...has anybody else looked at thier trans oil yet? I did not see the dealer said there was plenty of the ferous stuff on the magnet he shoved in the drain hole....It was bad enough to warrant sending a sample to mits for analasys

I did that back in February.
I just rolled into the throttle after a U-turn, and it started making a baseball card in bicycle spoke noise. I can't blame it for giving up the ghost after 90,000mi. That gear is the only gear that has to mesh with 2 other gears in the transmission. It does a lot more work than the rest.I'm almost ready for Devens.
I have some Powerslot front rotors coming for my car. I have some stainless steel brake lines to install. And I have some porterfield R4S rear pads to match the front pads I have been using for the past 2 years (and still look like they have 3/4 of their life left, amazingly).
