AT Power Needs !!
So since we have been hijacking other threads regarding AT power, I figured I'd start a thread for it instead.
What I am curious about is who has actually blown their AT apart? And even more..What was the critical failure mode? - Teeth shearing? - Input or output shaft? - Case cracking? - Bearings? Maybe there is a better way to make the AT handle 500wtq if we get more light on it.

Good idea!! Also if I'm not mistakes it's the tourqe that blows the 7AT not WHP. I'm interested to see where this thread goes.

Mine started letting go at around 500awhp with the G37x. It was shredding through the clutch packs due to a tuning issue not updating the line pressure correctly.

What was your wheel torque? Turbo or SC? What did you do to resolve the issue? What are you at now?

I was at 500.51 awhp and 430.27 wtq on a GTM twin turbo kit. I sent the transmission to Level 10 a handful of times to get their "bulletproof" package. After a couple of transmission volleys they decided to check it out and asked for the whole car. They figured out it was a tuning issue and it's been running great since I've had it back.
I'm currently wrapping up the final stages of the build and am hoping for a good whp and wtq increase over the past numbers.

Just curious... those of you who are AT that have gone FI or are considering FI - if you could do it all over again would you have gotten an M6?
I had planned to go boosted before I even bought my Z.. had even put down a deposit on the infamous GTM group buy several months before I had even begun shopping for my Z so I knew I would have to have an M6.. I also happen to prefer manual, but knew it was a requirement going in to keep boost prices down.

If the car was to run for 30 mins the transmission would just disengage and lose all gears almost as if we're to be in neutral.
Edit: First time this happen I got a solenoid code. Last edited by KN21283; 01-11-2017 at 09:06 PM. |

That's the effect. Do you know what physically went out in it?

Yeah, if I could go back, I probably would have gotten a M6 but at the time I was driving stick thru stop and go traffic regularly so I wanted a break.
I never really planned on going FI also. I figured that the power level was fine but as we all know. Once the mod bug hits, it's hard to stop. I haven't had any catastrophic issues with the AT but lately if the transmission oil is cold and I'm using manual shifting, when I slow down to a stop, I hear a clunk from the 2nd to 1st gear shift that the car does automatically or maybe I'm wrong, the car doesn't shift from 2nd to 1st automatically in manual mode. When the tranny oil warms up, I don't hear a clunk anymore.
