something like that.

the C4 is strange... it's a monocoque construction. the body was made, and then it was mated to the driveline. the driveline, thank's to it's construction, included the transmission, engine and suspension.

So yes, the pedals would have to be installed well before the chassis met the driveline.

 

GM makes up the RPO lists to designate options for GM cars. I posted GM's own list, but I am deemed wrong. GM has been out voted by the popular opinion of some poorly informed critics. This is not a popularity contest. The majority does not rule, in this. It is GM's list and they get to have it their way. Shoot the messenger if the news doesn't fit your preconceived notions, but you can't dispute what GM put into place, by a vote. Do you think a vote will actually turn the oil pressure switch into a low oil pressure fuel cutoff? I doubt it.

The height of conceit came with: How does anyone know what *I* have in the way of RPO listings. SurfnSun must KNOW what I have because he said that statement of mine was wrong. I want to see that proved.


I am as wrong as GM is on the list they published. You probably ought to take them to task, too.


I think you are the one with the self described head location problem. It has been demonstrated in this thread by me and others that ML9 is (per GM) the RPO for the C4 six speed trans. It isn't the result of a vote or by popular opinion, just fact.

Some people say that I know a lot. In fact, I DO know some things. There are lots and lots of things I don't know. One difference between me and some of the others, however, is that I keep my mouth shut unless I'm pretty darned sure of what I'm saying. A high post count is a poor excuse to get diarrhea of the mouth and start misleading the uninitiated.

I don't jump to conclusions. I read your content and take it for what it's worth. I don't criticize EVERYTHING you write, just what is wrong.

I said I would admit I was wrong, if I was... and I will.

RACE ON!!!

 

Ok...

1. Go look up redundant in the dictionary.
2. Apply it to the given scenario with dual RPOs
3. Apparently since Im wrong, explain to us what MN6 is since it clearly shows up on ALL 6 speed manual cars 1989-present.

The funny thing is even your supporters are now agreeing with what I said 57 posts ago.


Youre right, those posts were the height of conceit....you are not THE authority nor are you GM. You didn't even know MN6 existed.

But Im over this. Im tired of your dancing in circles.

 

The CORRECT RPO is ML9 and this is per Gm. Just because a manual car will have RPO MN6 on the console lid door does not change the FACT that the RPO is ML9. The MN6 RPO was probably used durring assembly however it is NOT the RPO for the six speed transmission.

 

Wow, Bogus bashing and meaningless trivia in the same thread!

 

This seems to make the most sense so far.
I think everyone agrees that ML9 is the RPO code for the ZF6.

However, as noted by more than one person here the code MN6 also shows up on the sticker (RPO Code List?) attached to every car, or at least the later models.

So, the MN6 was needed for something right? Even if just to get the car down the assembly line for the build process?

 

Someone show me some documentation from GM that says what MN6 indicates. Even the information I found is suspect because it's not from the General himself.

That's the point CFI-EFI and the few that agree with him are making. No one in this thread has been able to show where GM explains RPO code MN6.

It appears that all 6 speed cars have it, but it could just as easily mean bucket seats, disc brakes, or any number of other things. Saying that it indicates anything with 100% surety is wrong because no one other than GM can say for sure what it means. Until you find something from GM that nails down what MN6 is, all you have is educated guesses.

 

I thought this made the most sense and it was several pages ago.

 

Provisions for manual transmission. End of story.

 

I am not quite sure what your problem is. You are trying to pick on me, that's fine, but you are arguing with General Motors.

1. I am familiar with the word. If ML9 and MN6 are redundant designations, which they aren't (I'll show you why shortly) that doesn't make then both transmission RPOs.
2. MN6 isn't a specific transmission. It appears coincidentally with certain RPOs.
3. I explained from the start I didn't know what MN6 represented. It isn't that I'd never heard of it, it's just that I didn't know what it is called. I did know that it wasn't the RPO of a specific transmission. Here is where you shoot yourself in the foot. "explain to us what MN6 is since it clearly shows up on ALL 6 speed manual cars 1989-present.". If all six speeds, "1989-present" are MN6s but not all six speeds "1989-present" are made by ZF, then MN6 can't be the RPO for the ZF (ML9) transmission. Q.E.D.



I never pretended to be the authority. That is why I presented the GM RPO sheet, early on. I merely wrote what GM had previously supplied. It is you that were arguing against GM in the RPO list I provided, as printed by GM.



I am not dancing in circles. I haven't reversed myself once. It is you that can't keep your stories straight or respond coherently to a quote. The height of conceit came when you posted that you know what I had as RPO lists.Really??? That is wrong? What leads you to believe that I DO have an RPO listing that shows ANY "MNx" RPO codes? I'd say it's time to stick a fork in SurfnSun...

RACE ON!!!

 

I think through reading all of this I have made some sense of "MN6". It is only speculation, as I have no documentation. If you look back to the RPO page I posted, you will see "MX0 Transmission, automatic, overdrive (Merchandising Option)". Cars with either the RPO MW9 (200R4), or the RPO MD8 (700R4) fit the MX0 designation.

As it was suggested a ways back it does parallel the G92 situation. G92 doesn't specify a ratio. Only the "performance ratio", whatever that means. MX0 is an overdrive automatic, and MN6 is a six speed. None of these designations define anything specific. It takes the RPO (G44 = 3.07:1; MD8 = 700R4/4L60; M30 = 4L60E; and ML9 = ZF 6 speed) to tell us what the performance ratio is, what auto OD trans, or What six speed is in the car. These RPOs are not Corvette specific.

RACE ON!!!

 

I had said I wasn't going to post anymore in this thread but I can't resist.

THANK YOU! SEE WHAT I WROTE IN POST #6
Its only what Ive been freaking saying all along. Im glad we finally agree.

 

Josh, don't you have a STS thread to tend to? Or is tonight the night you go steal copper out of cats

 

Its platinum tonight Baby!!! That and Im stealing some turbos!! WooT!

 

Well going by the Black Book, which many here go by, it lists MN6 as the RPO for the ZF six speed from 1989-2004.

There isn't a listing for any six speed manual for 2005-6, but they do show MXO for the 4 speed automatic in 2005 and MXO for the six speed automatic(paddle shifter) in 2006.

Very rarely has the Black Book been wrong. Too many people rely on it for basic information.

 

this thread, like many others discussing RPOs, has turned into a real circle jerk.

 

And once again, you are putting words into my mouth. If you want to quote me, be sure to get the whole quote and in context. You forgot my disclaimer of, "I think through reading all of this I have made some sense of "MN6". It is only speculation, as I have no documentation. You cannot pick and choose my words, take them out of context, and rearrange them to suit your purposes.

I have provided documentation that ML9 is the RPO code for the ZF6. As I stated, POSSIBLY, MN6 designates a six speed in general, but that has not been shown. Even if it does, I have seen no indication that is designates the ML9, ZF6 transmission. I see no documentation from you.

RACE ON!!!

 

If that is what it says, then it is self contradicting. I believe, correct me if I'm wrong, that 1997 and up Corvettes don't use the ZF trans. Therefore, based on the definition above, the MN6 can't be the 1997-2004 six speed trans.


That squares with the MX0 as a merchandising designation or option as MX0 doesn't specify the number of speeds of the automatic overdrive trans. We know that RPOs do sometimes get reused, but only after a lengthy hiatus, like the LT1 engine. MX0 wouldn't be the RPO for a 4 speed auto one year and a 6 speed the next. Both those transmissions would have their own, specific RPO numbers, like the ML9 does.

RACE ON!!!

 

So where can I buy a 2004 Corvette with a ZF six speed? Maybe I should ask Mr. Antionick, or just have a vote.

 

Yea because GM has never ever reused a RPO option.
