Says the man with the crappy auto:icon23:

fix'd

:tiphat:

F-it I'm going to pull my trans out and put in the GT-R trans done.

Do it!!!!!! :woot:

After finally running this at the track I can say it seemed like it took for ever to shift in M-Mode after I hit the paddle. I am 100% sure I could shift faster with a 6MT. Just thought I would throw that out there. Would I trade my 7AT for a 6MT? Nope!

Back on topic:

Shumby any news from Sam?

So increasing the valve pressure so it shifts faster would reduce the chance of damage?

Couldnt you just have it shift only if the engine load is below a certain level (one that the transmission would normally experience on a stock engine? Then have the pressure increase after the clutch is fully engaged for a smooth shift. Then reduce the rate at which the throttle can open to reduce the sudden jerk that can damage the transmission.

Just a thought

As much as i like my 7 AT. i have to tell you that it just sucks if you punch it and your in 7th .6th or 5th. The car is just a dog in those gears, But in the 1st 4 gear's with 4.08's in the diff. Its a bear, it unreal how quick it is.
Oh yes and the fuel milage is not good 20 % less with the 4.08 gears and a low speed's in rush hour trafic the rev matching is a major pain.

So if I'm not wrong you are saying you just push the car till 4th not after that? more asking under normal driving conditions not on track or dragstrip.

And what do you mean by rev matching a pain

The top 3 gears are overdrive gears for fuel economy. It's a dog in those gears because you're at low RPM. If you want some power when you punch it, you have to downshift...

4th gear will take you faster than you ever want to go on a public road. If you're trying to accelerate hard, you should be somewhere in the 1-4 gears, yes. The rest is just there for fuel economy.


No idea, but I suspect he means he's shifting between 1-2-3 in M-mode while crawling in stop and go commuter traffic. If so, just put it in D, that's the beauty of the 7AT. Rev matching is automatic, so I assume he means he doesn't like it blipping the throttle when he's shifting at a crawl?

I always leave it in D mode for my regular commute. I have been thinking about whether or not I will do the 4.08 gears, but since the car Is a DD I'm not sure. I drive mostly on the highway and I get stuck in traffic like everyday. What issues might I run into with them? I know that fuel economy is one, but is there anything else?

this thread has been really helpful..this is my 1st z 2010 touring ..ive been a chevy caddy man for a long time..but something about the 370 for the 350 got me so im giving it a go...going with the greddy tt and greddy exhaust..tranny and rear were the thing i was worried about..also did a complete system component swap to the FOCAL...will have pic to post as i should have her back after tunning this week...any guys in baltimore md area lets hook
