Nope, I don't want to void the warranty. Besides, noize already tried running BG synchroshift 2, which worked miracles on the 8 and 9 trannies, and it didn't make a stich of difference. I would know too; I drove his car. My thoughts are that it's a very finicky transmission that needs a very special kind of tranny fluid specially made for it, and that no main stream fluid will work for it. It's like the STi; if you put anything other than the EXTRA-S fluid that is OEM in there, the car will crunch and ***** every time you change gears.

It's either that, or there's something wrong with the internals of the transmission and it's going to need to be replaced. I find it ridiculous that Mitsubishi won't keep it's EVO customers updated about what's going on with the car; I have to find out about the reflashes for the ECU on a forum rather than by getting an email or a phone call from my dealer. I think to myself, "wth most dealerships being totally clueless about the EVO and anything related to it, it's kinda scary that I have to be the technician and actually supply TSB numbers so that those morons can know what needs to be done on my car.

That's just sad. I love my car, don't get me wrong, but I hate the transmission in this thing. It's the roughest and least enjoyable to drive of any manual car I've ever driven. I've never driven a car that makes me cringe when I shift gears. I have learned how to shift to get around it, but even then I can't avoid it all the time. Ugh...

 

I completely agree. The only thing I would add to that is that its even more ridiculous when you meet with the Mitsu District Parts and Service Manager who denies any problem, issue, complaints or investigation concerning the tranny issue whatsoever on a corporate level, and then a week later a TSB comes out on the problem.

 

Guys, give the GM Synchromesh a try. Its not a miracle in a bottle - meaning its not a cure-all for the tranny, but it is 10 times better than the factory stuff which had me grinding going into second gear constantly. I have had the Gm stuff in their for over 700 miles and I have not grinded shifting into second once since putting it in. The feel is still slightly notchy in some gears but it is definitely better.

Perhaps the Syncromesh is different than the BG Syncroshift. I have a 30 gallon container of the BG but haven't tried it yet.

 

Its not the fluid, its the design. If BG doesn't make it better, nothing will. Its not like there is some magic fluid out there that will cure slow shift partial throttle notchiness. If there was, Mitsu would have released it. They already came back and said its operating within the design specifications.

If one of you really cares enough to make something happen, be the first to send one to TRE or Shep. I guarantee you those guys will figure it out very fast.

 

today two subaru guy drove my car. Both without my question said the tranny and the steering is amazing. So i'm sure now, it is not just me who thinks my tranny doesn't grind at all. And smooth too. By the way 4 other X member friend with no issues at all. No grinding and so on.
So i dont know , can be a bad batch in the evo line?

 

So the improvement in shifting that I am experiencing with the GM Synchromesh must be my imagination. You haven't even tried it and you are making these claims. Like others have said, BG works great for the 8 and 9 but that doesn't necessarily mean it will work well for the X. This was my reasoning for putting in the GM Syncromesh rather than the BG.

 

I don't know, but 4 of the 6 X's in town here all have the same issue including mine, I have yet to talk to the other two.

 

The X is a IX transmission! It just a slightly modified and freshened one. The BG feels slicker and I thought it was much nicer at first. But I can still "make" it notch, I just have adapted my driving so it never does. The thing for me is that I have gotten used to it. It doesn't seem as bad unless I drive an VIII or IX, then it pisses me off.

There are a lot of people who just drive differently. I have a friend who drives my car and the way he shifts, it never does it.

I won't but GM Synchromesh in my car. BG has been recommended by Mitsu mechanics, I have never heard of any of them recommend GM.

 

^Well, it is and it isn't. I mean the new tranny has the same basic layout as the 9, but it has thicker, wider gear faces on all gears which is why they deleted a dedicated reverse gear so as to save weight, and the X has tripple cone synchros on 1st through 3rd with double cone on 4th and 5th. The 9 had tripple cone synchros on 1st and 2nd with a double on 3rd and correct me if I am wrong but just a single on 4th and 5th.

So technically there really is a lot that is different about the tranny, but my suspicion is that it has something to do with either the fact that it has tripple cone synchros on the first 3 gears, or it's something to do with the reverse mechanism that meshes 1st and 3rd to create reverse. Maybe the collar that engages 1st and 3rd is causing an issue, or perhaps the new synchros are made of a different kind of metal and they are more finicky when it comes to fluid.

I know my STi was this way, because it hated everything but OEM. Oh if only the X were that way... maybe it is and mitsubishi just didn't choose the best fluid from the get go. I have suspicions that mitsu was aware of this right at launch and that they have fixed something internally in later date Xs. This is one possible explanation why some peoples trannies are smooth as can be in their Xs.

I think that if that's the case that mitsu is being cheap and trying to see if they can find a bandaid to keep from having to spend money on replacing trannies in all of the december through february built Xs. Who knows... then again that wouldn't really make any sense because they didn't change anything from the japanese model and those have been out since like october. Is it faulty assembly on certain affected vehicles then?

Would that be why some seem to be fine and others are like ours? Questions, questions, questions and NO answers from mitsubishi. What a shocker. The funny thing is that I know they are reading this forum, quietly lingering in the background saying nothing for fear of being flooded with questions that they don't want to have to answer. Thanks guys!

Look, I don't mind spending 35k on a first year car that has some issues I really don't, but for god's sake keep us up to speed and tell us about what's beng done to fix this. If it's a fluid issue, then I want to know what kinds of fluids have been tested. If it's mechanical, then I want to know what the suspected cause is and the estimated solution. Speak up and quit leaving us in the dark.

 

I 2nd that motion. Stop putting out TSB's regarding these problems, but telling dealerships not to touch it.

 

Any updates from anyone on anything?

 

I took my evo in for a reflash, they said there were no updates for mine in particular. I had an idle issue, I had read of some reflashes available, but mine must not be one of them or something, the idle issue prolly had something to do with our weather/condensation? They did - for free - adjust the clip on my side spoiler because I had hit it a few times getting in and out of the car... other than that - nothing new - sometimes I drive it and its fine - sometimes I drive it and its not. I have asked them to replace my clutch, but again they need approval from the rep, hes supposed to be in sometime in July, we shall see.

 

I don't think the clutch is the issue. Either way, I'm glad that your new tranny is just the typical notchy type like everyone elses and not being more problematic like your first one. You probbly just got a bad tranny when you got your car but that's what a warranty is for. Don't take no for an answer on the reflash though. Get the TSB number from this forum in the appropriate thread and present that to the dealership and make them do it for you. They are not doing their job if they don't.

 

Been there tried that. I keep getting told that the Mitsu rep says they are not allowd to touch my car at all. And said with the reflash the ONLY way they will do it is if I get a CEL. Without a CEL, I have to deal with it.

Again the dealership has seen and noted the problems, and says I don't know why they won't fix it, but the Rep keeps saying no. They won't even let them fix my seats or my rattling rear view mirror. Sigh

Mitsubishi ftl

 

Well my tranny has been getting worse, shifting from 2nd-3rd grinds horribly I cant do fast shifts to get it in smoothly (does it at high or low rpms), it just feels like my syncros are toast. I don't know if mitsu will do any thing about this. I will be taking it in on friday.
