Default Help with MGW Shifter Issues

Installed the MGW over christmas, and i am having some issues with a rattle. First, let me say that the shifter from MGW is definitely a well engineered piece of equipment, and have nothing bad to say about it. I understand every car is different, and and george can't make one part that works precisely the same in every corvette. Car is a 2008 vert, Z51, 10 months old with 11000 miles.

The problem is a rattle (like a tapping) noise at wide open throttle, especially in 2nd gear, less in third. Under normal to spirited driving, there is no real issue with the sound. I really don't believe it is the shift ****, as the sound seems to be coming from behind the console. I pulled it apart last night, and test drove without the console on. The sound was way more pronounced. The noise seems to be coming directly from the transmission. With the console back on, the noise seems to be funneled through the top of the console.

So a couple of questions:

1. Is there anything in the installation which would cause this? like how tight the bolts are on both the shifter and the interior cover. I put the interior cover back on the way it was, say a quarter past finger tight. but the 4 hex bolts had no specific tightening specs.
or the modifying of the inner shift boot. I opened it up enough to get under the top crease of the MGW boot.

2. I didn't notice this with the stock shifter, and will have to put it back to test that. But assuming the shifter is the issue, could i be doing harm to the transmission?

I love the feel of this shifter, and like i said, under normal to spirited driving, it is not an issue. I would love to fix the problem, but I could probably live with it as long as i'm not doing any damage to the car.

Thanks,
Kevin

The issue is not the shfter, it's the stock ****. If you take the **** off there will be no rattle (at least on mine and many other's). You have to decide if you want to go with an aftermarket shift **** or put up with the rattle.

I am using the stock **** on my aftermarket shifter. Lucky I have no noise's or issues. I'm assuming you used a gasket between the shifter and the transmission. My stock gasket was perfect and not stuck down. I just tightened my bolts pretty snug. Just go for a drive without the **** to tell if it's
the shifter.

Mine rattles at WOT especially when cold. It is not as noticable when warmed up, but it still rattles at WOT.
I am too using the stock ****. I have not tried to see if it rattles without the **** on. Everything feels quite tight as well.

The **** is not the problem. It's how the shifter -box- fits into the chassis combined with the varying tolerances of all the mechanics between. and including, the tranny and the shifter box. Changing various components can increase, decrease, or eliminate the problem. It all depends upon the individual car. The fact that temperature changes mean rattle changes is a good clue for this. Some people never have the problem. Some people can't fix it no matter what they do. Some don't have it until the change something. Some have it until they do. It's all over the map.

What you might try is putting a couple of thin washers between the shifter box and the chassis to lift the box just a tick more off of the chassis. This *might* eliminate or reduce the problem. You don't even need to remove the shifter fro the box to do it.

It's worth a try. Your mileage may (and almost certainly will) vary.

There are a *lot* of threads about this in the C6 Z06 forum that you might want to browse through for more info on what's going on.

My Z06 had the "rattle when cold" issue straight from the factory. And it was *loud*, too. (If you think about it you'll probably realize that "cold" doesn't mean the engine but the chassis itself.) I Installed the MGW and the rattle was still there - no better, no worse.. So I switched the shifter box from the stock Z06 box to the stock C6 box (the one you have in -your- car ) and the rattle was *gone*. Totally. 100%. Cold or hot. I didn't change the **** (MGW race ****.) I changed the shifter box. That's also a clue.

Sorry, but you're comparing apples and oranges.

The OP has a C6, not a Z06. One of the cures for the Z06 is the C6 shifter box. A C6 already has that box. That isn't the issue.

The issue is the stock ****. Even Z06 owners that have used the C6 shifter box have had this problem. It's a five-minute test to prove. Remove the stock ****. Drive hard. Notice the lack of noise. Re-install the stock ****. Drive hard. Hear the noise. This is old news.

Some have used a heavier shift **** with success. Some have used an MGW ****. You already had an MGW **** so of course when you changed out the shifter box you were "cured". Try throwing the stock **** back on and you may or may not have noise. Some do, some don't. I personally haven't felt it's that big of a deal. I may deal with it later, but I have higher priorities.

I have the MGW long handle and it rattles every once in while.

What is the shift box that people keep referring to?

The box that has rubber grommets between the box and the body (at least on the C6). Many Z06 MGW owners find swapping the Z06 shifter box for the C6 shifter box helps to reduce the rattle.

[sarcasm] Gee, thanks for filling me in. You're right. I'm an idiot who's never dealt with this issue nor can I tell a C6 from a Z06. [/sarcasm]

Go back and reread the OP's description of the symptoms.

My point was that by changing some of the the dynamics and/or measurements of the stock system you can POSSIBLY affect the problem for the better.

It's unlikely (but not impossible) that the same car design (the C6 and the Z06 *are* fundamentally the same car) would produce the same symptoms for the same problem via two (or more) different causes. My premise is that the same issue is in play on both models. The C6 box cures the rattle on some/many Z06s. That's not surprising since the earlier Z06s had a different shifter box. (The newer Z06s have the SAME box as the C6.) The C6 box does NOT cure the problem on ALL Z06s. This implies variances in the other components - components that are SHARED between the cars. Those components include the chassis itself, btw

My car rattled exactly the same way as it did WITH the stock **** on the stock shifter. Changing to the MGW shifter + race **** changed nothing, nada, zip, as regards the rattle issue.

This offers nothing that can be used to narrow down the the problem. The question here - inherent in your own statement - is this: "If the ONLY THING that I changed was the shifter box and the problem went from unbelieveably loud to totally non-existant, then what was the problem?" The shift ****? Really??? I think not. There is something more fundamental operating here. There may be cases where a different **** affects some harmonic and masks the problem but that doesn't mean the **** was the problem in the first place. If an aspirin cures my headache it doesn't follow that I was suffering frm an aspirin deficiency

Zoxxo,

You have the MGW shifter ****. I don't. When I remove my stock shift **** the rattle is gone. With the stock **** it rattles. With only one different variable I can safely say the stock **** on my C6 is the problem (for me). Others have had the same experience (Z06 and C6 owners).

Your scenario involves a Z06 shift box versus the C6 shift box and an aftermarket shift ****, so you have two variables. I don't. If the C6 shift box fixed your problem, great.

I wasn't trying to argue, but this really is old news and one thing that is consistent is that what works for you may or may not work for me, regardless of whether we have the same car, shift box etc. Some with the stock **** have no noise, some do.

As my shifter/box is silent without my stock **** I really want to try a different shifter ****, I'm just not looking forward to installing a new shifter shaft and **** to "maybe" fix the problem.

I have to admit i was wrong, it is the shifter. Quick run with no shifter, and could hear the noise. There is some play between the ring at the top of the shifter, and this may be a contributing contributing factor.

I ordered the MGW for the stock ****, are there aftermarket ***** which will work, or do I need to change the top part of the MGW?

Thanks for everyone's input, and I hope everyone has a very Happy New Year!

There's a different shaft for threaded ***** (non stock *****). You may want to look into your install as I haven't read of one C6 making noise with the MGW shifter that wasn't related to the stock ****. Typically when the **** is removed from the equation the shifter is silent. I'd love to hear from anyone with a C6 that has had a similar experience to yours.

That has always been the case with the C6 from all accounts I've read. I have yet to see someone with the C6 have the rattle without the stock shift ****.

I have a 07 Z06 with most of the bolt ons that one can do, headers, big cam, LPE heads etc etc. I installed a MGW shifter with the stock **** and got the rattling shifter ****, more like a knocking **** upon WOT or near WOT in 2nd, and 3rd gears. I tried various fixes which none worked, I later replaced the MGW with Georges latest rendition which helped. In the end I replaced the hard mounted Z06 shifter box with a standard C6 box and that helped tremendously, both on my car and two customers cars with the same shifters. On the other hand you already have the standard box, which I can't explain why you have this annoying rattle in the ****. One of my customers stuffed some high density foam inside the shift know and forced the **** onto the shaft which he swears virtually eliminated his rattle.

Well first of all; I too just installed a MGW shifter. Unfortunately living in Chicagoland (5 inches of snow on the ground and -1 temperature at this time, I will not be driving my car until spring. I have installed a Hurst shifter ball and noticed that the Hurst ball was extremely tight and the stock shifter handle was actually loose, as I tried both just to see for myself. I can't tell you if my shifter rattles yet, but I would be very curious to hear from George @ MGW and listen to what he has to say. I know MGW is closed until after the new year, but George, if you are out there, can you please respond?

PS: The was a disclaimer in the paperwork that states there may be a rattle especially when the car is not warmed up.

TJ, I've stuffed my stock shifter **** full of lots of different materials and cannot rid it of the rattle. I've used teflon tape as well and nothing is working. If I pull the **** the shifter is absolutely silent. I really think another shift **** will cure my ills but I'd have to swap out the shaft and **** and I'd be pissed if I still had the rattle. Like I said before, some have the noise and some don't.
