Think about it: There's a real reason that higher end manufacturers are putting in expensive, heavy systems like PDK and DSG (the true semi-automatics which are basically sequential manuals with automated clutches), instead of just using ATs with paddle shifters. ATs are fluid drive (lossy/inefficient) and slow to shift. The one nice thing about the AT system is the fluid torque multiplication, which really can help in the low RPMs. In truly aggressive/track driving situation, the 6MT has the edge in shifting speed by a mile. Your quoted numbers are just the physical shifting time (e.g. in D-mode drag racing), you have to add on top of that the input delay on the M-mode system, which you're going to have to use for any serious driving (downshifting). A good 6MT will beat that any day. I've gotten used to the 7AT's shift delay to where I can compensate by shifting "early", but it took a while to get my brain to do that reliably. There are other things you have to re-teach your brain about too, like not dropping off the gas pedal until after you upshift instead of while upshifting (or else the 7AT gets confused and shifts extremely slow and clunky).

I love the 7AT, it's a great transmission for a mixed-use car, I just think you're taking it a little too far in claiming it's superior in every way to the 6MT. It clearly isn't. |

The reason that I am in 5th gear is that i have 4.08 gears in the diff. The factory diff is 3.33.
First and 2nd gear are just a blur. I also have 305 35 18 M/T drag radials on the car and i run them at 23 lb's of air. the traction is perfect on a prepaired drag strip. If the track has not been prepaired then they spin in the 1st to 2nd and 2nd to 3rd shift's z

1. Your car is not my car and I have no shift delay in M or D mode. 2. In stock form, with non pro drivers, the 7AT has proven to be faster. (How can that be if....as you say.....ITS HEAVIER.....SHIFTS SLOWER.... and.....IS NOT AS EFFICIENT?????) 3. You cant imply/expect every 7AT car and driving experience to be the same as your car. I dont think I have the fastest 370....BUT....if you were to ride in MY CAR.....your opinion on the 7AT would change. 4. Z1 Motorsports has done several 370 GTM TT installs (including a Nismo). Mine was the first 370 they did and they EXPECTED the 6MT to be more stout when they finally TT'd one. To their surprise IT WASNT. According to John @ Z1: All things being = (boost, mods etc..) my car was faster/stronger. NOT MY WORDS....JOHNS. 5. You seem to only be able to see things from your cars point of view.....No where on this forum have I heard anyone else talk about a shift lag on their 7AT in M or D mode. Based on this, I think you need a tranny tune or that the issue is individual to your car. 6. If you need more information about the Osiris tranny tune you should call John @ Z1 motorsports for the details on how its done. He was the one who did my tranny tune. 7. This topic (tranny tuning) has been heavily discussed on this forum for many months/a year. Originally, it was passionately discussed because 1 person on this forum (Shumby) blew his tranny up when he added an SC to his 7AT 370. Because of this perceived possible issue, we were all (FI people) trying to do what we could to potentially prevent this. So again, while its new to you, this is about my 20th discussion on this. 8. Lastly, if you feel your tranny is inferior then go buy a 6MT. I dont and I am done with this conversation. |

I never understood this debate. I hate when people just sit here and talk about how they bought the automatic cause it was faster. Like .2 seconds really makes a difference in your everyday driving. If I was going for a straight drag car and that was it's only purpose then I would of went automatic but for being daily driven the 6mt is much more fun in my opinion. For somebody to sit here and say the 6mt is garbage because it's .2 seconds slower is ignorant I think.

I've never even been there and I understand lol. I feel so bad for you guys that get caught in rush hour out there. That would drive me up a wall, and yes I would be begging for an automatic if I did have to deal with that lol.

I've had both the 6MT and 7AT 370 at the sametime. They both have pros and cons, the 7 was faster at the track mostly because it was easier for me to launch. This is a personal preference thing and there really isn't any reason to fight about it. I ultimately sold the 6MT, but it was because the wife refused to learn how to drive it and she pays the bills. IMO 6 more fun on open roads, 7 easier period.
