There's a lot here about personal preferences between the C6 transmissions. I want to get technical. Does anyone know the 0-60 performance difference between the 2 transmissions with the Z51 package.
Thanks!

 

From what I've been able to gather, about 1 tenth in 0-60 and 1-2 tenths in 1/4 mile time. The MN6 is faster the A6 as usual is more consistant.

Basically it boils down to do you like to shift or are you content letting the computer shift for you. With the A6 you do have the option of using the paddle shifters, but it's still not shifting for yourself.

I bought the A6. I usually buy manuals, but the Tremec T-56 is just not that great of a transmission for shift quality. That took enough joy out of it to convince me to buy the A6. I'm happy and wouldn't change it after 3500 miles and 8 months.

I've owned a couple F-bodies both A4 and MN6, an 02 Z06 and a GTO with the MN6. I'd take the MN6 over the A4, but it's close, the A6 works better for me though.

 

You really have to know how to drive the M6 to beat an A6. I've said it before and it would seem that I have to say it many more times to get this through everyone's head-

Most M6 drivers cannot shift anywhere near as fast as an A6, even at their best. And I mean without grinding gears, or missing shifts. In the C5s at least M6s have gearing advantages and rwhp advantages over the A4, and it's still very hard to find a driver that can beat one at the track.

For every Ranger there are probably 9 other manual drivers that think they can beat an A6, but can't.

My cousin has lots of experience racing manual Mustangs, and he is an amazing driver, one of the few that could beat an automatic counterpart- and he's still very good. His friend had an automatic firebird that ran dead heat with him until he blew his auto tranny. The friend told the tranny guy to make it shift as aggressively as possible, and he never beat the guy again.

That's how the story goes, and I don't think he would lie to me.. especially seeing as how he still doesn't like automatics- but acknowledges that they are better for drag racing.

But that's all 1/4 mile talk. In the 0-60 you only have to shfit once, and I would think a decent M6 driver that could hook would have an advantage over the A6 in a 0-60 situation. I consider that less important however since I've never had a race end at 60.

Oh yeah- lastly, with the paddle shifters the manual loses it's downshifting advantage during roll races. it still has a slight top end advantage however becuase of the gears and slightly more rwhp.

 

Thanks for the inputs! I've ordered the Z51 which comes with special gearing on the Manual but not on the Auto.
I have never had an Automatic in a sports car, and this will be a toy. But, today I drove a Paddle Shift. It was very nice, and I sensed was every bit as fast as the Manual. I just really can't see paying $1,250 for this option, except that my wife can't drive a stick ... which is probably a good reason to get one!

 

Get the Stick.

 

Actually, get what ever floats your boat. I got the Manual simply because I love shifting gears.

 

I would definitly agree with this. If I drag raced this car, I would personally probably win more drag races myself with the A6 instead of the Tremec. Although in the right hands the Manual should be superior.

That is why I got the manual too. Even for my commuter Honda Accord I got the manual, not because of better milage or anything else, but just because I like to shift.

 

I must admit that after getting an A6 I miss shifting like I had in my 99. However, that said, the auto's are more consistant. I could outshift an auto. And bone stock the M6 is faster. But, it's not as consistant. And when I got the A6 I didn't have to put in a CAGs switch, and a short throw shifter...and my sweetie can drive it if she has too. All good reasons. I personally miss being able to snap alittle rubber between shifts. But I don't miss the smell of a burnt clutch...

 

For Z51, it's called "MZ6", not "MN6"; MN6 is for non-Z51 cars.

 

Its a sports car, get a stick, same reason bikes are are manual, for performance and control. With a manual, you control when you want to shift. When I get arthritis, I will get an A6 .

 

100%

 

got my a6. boy do i miss my clutch sticking to the floor on aggressive runs. NOT!!!

 

Get the manual - driving a corvette with an automatic is like having a manual in a minivan. Some things go together and some things don't.

 

My old 96 A4 Z28 has already beaten many M6 corvettes, but I still prefer my M6 corvette over the Camaro, so I sold it. Sometimes its more about how much fun it is shifting, than just hitting the gas and holding on, and with an auto thats all you have!!! BORING!!!

Now I just need to practice up and get the HP up a bit in case I run across the guy who bought it!

Also, keep in mind, on the street most of the time its a rolling run, so I can downshift and have a lot more control over the power band than any auto could. So I dont worry about beating an A6.

But from a dead stop, you need to be perfect with a stick or you lose, simple as that.

 

True, but the A6 has narrowed that 'highway roll' gap between automatic and manual a bit as well.

 

 

You forget that the A6 can be manual also.

 

So if properly/equally driven which car is technically faster?

Sometimes I wonder if people have every driving the A6. People think that we all drive around in "D". Yes that is where it is most of the time, But then again I'm on the intersate most of the time.

But for 2 lane roads and the twisties it's in "S" and the paddles are engaged. I have the same control over the power band as any manual. And I can still shift faster (other than 1st to 2nd). Sooner or later someone will break the code of the TCM and get that fixed.

 

The manuals have the HP/Tq advantage. It's only about 20HP/Tq but that will make a difference. Of course that is stock to stock.
