6MT vs 7AT and the Track/Auto X

kannibul

Seems to work fine for me, but, then again, I've yet to hit a "track" with it.


The manual's only advantage on downshifting is that you can skip gears easier.

Ha ha ... comparing your Zs AT to your trucks MT is not at all accurate man...

kannibul

You're right, I should compare my trucks 5MT to every other MT vehicle I've driven...oh, wait, I have, and my statement still holds true. My trucks 5MT is just as fast between gears as any other MT transmission...I can bang from one gear to the next just as fast as anyone on here, and just as fast as that video posted above, if not a shade faster. Granted, my truck is a POS 4-cyl that can't accelerate worth a crap, and when I do shift like that, I can feel the engine being dragged DOWN to the new RPM, but, I can easily shift that fast...

So, better explanation 5 steps in a manual...

1) Let of the gas
2) Push in the clutch (can be done at the same time as step 1, goal is to not let the engine "spin free", or drag)
3) Shift gears (not a lot can be done here to speed things up - physics!)
4) Let out the clutch
5) Give it gas (this can be done with step 4 if you don't mind burning your clutch)

Now, if you skip step 1, you're power shifting, and I bet you'd STILL be slower than the 7AT in shifting. You could save even more time if you don't care about getting a new transmission, and just slam it from gear to gear, if you're good with your throttle. I've done it with my bike when I got in a wreck and rode it home with a broken left wrist...can't work a clutch that way!

There's not much that you can do to make a shift between gears happen faster with a manual..you have a stick that you have move to get to the next gear, and synchonizers that DO slow the process down a bit.

7AT does what - release a band or a clutch pack? The difference with the 7AT in this car and most autos is that it's not trying to be smooth, it's getting the job done the way a sports car should. Snappy...

I believe he meant that your comparing your truck clunk box to a true sports car manual transmission, completely different gear ratios, shift throws, etc. If you cant shift faster than your 7AT, then my friend, you just arent that great of a shifter. Its ok to defend the car you drive, thats all fine and dandy, but the car will not be a solid track performer in stock form, the 6MT will always have the advantage on an auto X track. If its racing you want to do, leave it to the drags.

Have you driven a 7AT Z...in manual mode?

I'm also not defending what I drive...I'm stating what seems to be contrary to what a lot of people think regarding the 7AT.


You realize that the average person's reaction time at a drag strip is around 500ms - right?

At least, those who don't try and anticipate the light.

It still has a torque converter. "Manual mode" means squat as there is nothing special about the transmission. It's akin to "manually" shifting a Honda Accord between 1-2-3-D and thinking it makes a difference in performance.

kannibul

Again, have you driven it?

And, yes it is different. Once you put a honda in D, it'll downshift if you mash the gas, and shift early...

Not so with the Z's 7AT. You put it in manual mode, it'll stay in that gear come hell or high water....with the ONLY exception being that the RPM drops low enough that the engine could stall.

And, regarding the torque converter - it locks early and it locks hard. You can engine brake with it. When is the last time you could do that with an automatic...seriously engine brake...I'm not talking about dropping it in a lower gear and having it wind up a little. I mean 10-20 seconds of straight engine braking from highway speeds on down without touching the brakes, downshifting from 7th, to 5th, to 4th, to 3rd, to 2nd and watching your RPM guage go smoothly from 6K on down, with no "drop" due to the TC going limp...and know that you can hit that throttle and bust the ***-end loose at any time from 3rd or lower?

I test drove one before mine, felt like an automatic.

^ Likewise... but I never would have gotten any non clutch short of a DSG

Honestly Kannibul, my wife's CX7 acts just like the Z's AT. The Z's AT does shift however.

kannibul

I have a 7AT....I've owned many manuals and automatics, I know they work...

Sorry Kannibul.. I mean to type the Z's 7AT shifts FASTER!! My fault... But, my wife's CX7 acts just the same.

I am impressed that the Z's tranny shifts SO fast when copared to the other modern 'Sport' At's. However, I have my doubts that it would be good on the track/autoX.

kannibul

Stay on topic

i like my wife's!!
