That's what I thought and if the Mitsu rep approved it post haste you would have to think he knew what he was doing seeing that it costs them so much money.

 

Sent you a PM bro, thx in advance.

 

That's interesting, I spoke with the service manager yesterday and they installed a new crank sensor with out a fix. It's definitely hesitating and gets worse after an hour and a half on the freeway. Let me know if the tranny replacement works. I wish they would have done it by the second or 3rd time in instead of giving the run around. Hope it works for you.

Transmission being the cause was also noted by someone else back in Oct.

Good find n00dle. That should help you guys out.

FYI, when I went to my dealer I brought a print out of several posts from this site. They were happy to read through them. Every little bit helps.

 

The guy was a member here who also went by the same name here and posted a lengthy post about his ordeal here on Evom. Tried a search, but apparently he's no longer a member here
At the time I thought it was kinda weird, but now this is the 2nd time i've read about it so I just wanted to let you guys know it's not the first and perhaps there's some truth and hopefully a solution.

 

Yes all of this is excellent news. All I've been looking for is a solution, and some hard evidence, and I think we might have it folks. More to come after I speak w/ my SM tomorrow.

Thanks to Bob for taking the time to come back and post his experience, and n00dle for the research!

 

thanks for the updates guys.. lets keep this one goin!

 

Spoke with the SM today. He mentioned he spoke with a drivetrain engineer at Mitsu and confirms that this could cause the problem, but he's not sure if it's a 100% fix, anyway they have a tranny on order (they're on backorder from the factory) it can be a while before they get it in. Hope this does it. I'm still proceeding with the lemon law though. What if this would have happened when my warranty was out of service, this would have been a very costly fix. I think my future with the EVO is done.

 

More interesting news. I spoke with my SM again last night. He said this might keep me without an issue for the next 4 or 5 months or fix it for good. He also said that this will buy Mitsubishi some time to get their most senior engineers working hard on the problem.
I would proceed with the Lemon Law too Jess. It is hard enough to make it stick, there is no reason to stop now, but ask your attorney if the replacement tranny might make it more complicated.
So what does this mean? Damn if I know.

 

Basically it means that they don't know wtf is really causing the problem, but they do recognize it, are working on it, and are willing to try different things to replace it. I can only imagine the look on the tech line person's face everytime they get a call from a service center asking about this issue...

 

OK so the frustration continues...

Just spoke w/ my SM. He has been told by tech line that they are _not_ doing the tranny replacement anymore because it's not a real fix (it only dissipates the problem for 4-6k miles) and because Mitsu doesn't want to waste money replacing $$$ trannies on every evo. He also said there is apparently an ecu fix already out in Japanland, but it won't be available here for another month or so (gee that would only be 3 months late from the original release date).

So I pleaded with my SM to call the district rep and get this tranny replacement authorized. He is going to speak with the DR and see what he can do.

I don't really give a **** if it costs $4k for mitsu to replace it, and he is more than happy to do it because it's work for the service department. Mitsu ought to be replacing these trannies without question to anyone who asks for it, there is no excuse and no reason to deny those who are actively experiencing this problem!! It is totally unacceptable to me to hear "well you'll just have to wait". Unless Mits. wants to pay my car payments while I "wait", they had better be doing everything they can to alleviate me of this issue, inclusive of a tranny replacement if it will buy me some trouble-free time between now and the supposed May release date of this reflash.

 

Future issues with this problem might come back to haunt us when our warranties are up. I just don't think the EVO is reliable enough for me to keep in my household. Don't get me wrong it's the best car I've owned as far as performance goes but not worth the cost in the long run. My lawyer has reviewed all my documents and my car more then qualifies for the Lemon Law in Ca. (4 times in the shop without a fix or 30 days in the shop.) My car has been in 5 times, it's still in, going on 3 weeks all together now. By the time the new tranny is in it might be 30+ days in the shop. Even if it's fixed it'll still be a LEMON in Cali.

 

jess it's only a lemon if you turn it in under that premise right?

I hear you on reliability, but I'm not worried about that myself. Aside from this issue, which is recognized, there aren't any other issues to worry about.

 

Remember guys, just because the tranny is letting out harmonics that are interfering with the ecu's knock sensing, it doesn't mean there is a problem with the tranny. All moving parts give out harmonics of some sort. And as those moving parts wear in/seat properly, those harmonics will shift frequencies slightly.

Putting in a new tranny, you will get the harmonics of an unseated gear set etc. Those sounds apparently do not interfere with the ecu. But once it is worn in, the frequency will again shift to one that interferes with the ecu.

The fix we need is in the ecu.....not in the tranny.

btw, I got my ecu Dynoflashed this weekend in hopes that it would take care of the problem. It cut down on the number of cels I have been getting, that is for sure...But it didn't cure the problem completely. But as a side bonus, I now have a much fatter power curve!
