Kormex Tranny Issues !!!

[VRFury]

I am concerned reading this. I have had similar issues in years past, and now I'm sure I have a clutch dragging issue. I firmly fought the idea of not resurfacing flywheels for years. I have learned that mitsubishi is, indeed mightybitchi. I don't believe in resurfacing these damn flywheels, and I think that alot of installs are butchered, as noted before. In addition, slaves and masters are only now seeming to be something people consider replacing as much. I also believe many aftermarket clutches are not quite correct. I had a conversation about this with bret once upon a time. Even with that considered, parts can still be made by somebody on a bad day now and then, and unfortunately, we are sometimes left with the issues. I certainly think this particular problem sounds like a clutch issue, and I would get a new OEM flywheel, and I believe you didn't mention your slave, so I would recommend that too. I have had some vehicles that no matter what diagnosis I try, or how many veteran brains get involved, some shit is just bad. In ways not always very measurable.

As a matter of fact, that brings up something that just happened a few weeks ago. It is a GM manual in a dump truck. Same(I believe they said) as in heavy duty pickups. The pressure plate has a plastic wheel if you will, that adjusts as the friction and plate wear. However, It is adjusting up immediately, and acting somewhat like the problems we are discussing here. General Motors does not even have a fix for it. This is not a brand new truck either. Its a flawed design from a few years back, and overcomplicated. Much like our mitsumopars. Alot of times, in fact most, the more complex, the more parts costs involved. Its unfortunate, but being in the field,(and owning this mitsu) I've come to understand this. These cars are more of a parts cost car, not a 'slap it in like an old camaro' kinda thing. And hey, they had other problems anyway.....like being a chevy

kormex trans parts

as a changeover but the guy doing the box is looking to having everything rebuilt here in Australia. I'm not sure what option is best, I am looking at putting more power into the car as the years go by and I am afraid that if I'm still stuck with the 18 spline it'll just break again. Any words of wisdom woud be greatly appreciated.

Check the wiki forum and look for the topic "Everything you need to know about your AWD drive train." It will tell you how to get around the weak 18 spline output shaft in a cost effective manner and advise you about your TC. I would be weary of replacing all the bearing and synchro rings just for the heck of it. If it shifts great now, I would advise you to not mess with the rings as you will just accumulate unnessisary cost. But because the output shaft needs to be replaced, I would have some one go completely through the tranny, clean everything, and replace anything questionable. But no need to replace parts just for the heck of it. Deffinately go with who you feel comfortable rebuilding your transaxle though. If you trust this guy, then use him. If not, then do not be shy about getting some one else to do it.

VRFury - I remember that conversation. SPEC has updated the design of their sprung clutch hubs for increased duribility. I do not believe we have seen any trouble from them thus far. I am still a fan of a heavy flywheel on the AWD cars. If there is anything else I can help you with just let me know. Most of the cost I have seen that is associated with these cars can be linked to owners not exploring their options and lack of knowledge. I had a real close friend of mine have that happen to him recently. He was too eager to get the car on the road and he ended up making a big desicion with out exploring his options and it came back to bight him in the butt... and wallet... That is why I try too pass on as much info as possible to people, because they make better desicions that lead to happier owners with nicer cars and fatter wallets. I would not worry about GM though, they are so big the left hand does not know what the right hand is doing. That is why they continue to make the same mistakes they have made decades earlier. Like bankruptcy and public appologies for making subpar products.
