Default Sock vs already upgraded 7AT

Please bare with me and keep in mind I am still learning about our cars, even though I've owned mine since it was new in 2010.

I read through the entire 37 page thread and I have not seen anyone ask this question. The Stage 1 kit on a STOCK engine will still be ok with a stock 7AT. Now...how does that work if the stage one does put it close to the stock 7AT limits and you already have the dual cold air intakes, headers, straight pipe or hi-flow cats, and cat back exhaust. Won't those extra mods that add a decent amount of extra power push the stage 1 over the limits of the 7AT?

Also, the intercooler placement, how will that affect those that already have an oil and trans cooler.

I am asking because I already have the Stillen Dual cold air intakes, headers, hi-flow cats, cat back exhause, and Oil and trans coolers. I am definetely insterested in driving my car down to your shop around the end of this year and having the trans upgrade and your stage 2 kit installed, maybe a few extras depending on the price.

They are looking into a serpentine setup. They are looking at running either an 8-10 rib setup.

The 7AT is marginal even with the Stillen kit which produces far less torque lower in the RPM range than a positive displacement supercharger. I can't imagine the transmission lasting long with any spirited driving.

True and the 400wtq is just a guideline. Its not like if you keep it at 390wtq you are guaranteed to not have a problem. Someone could go 50K over 400wtq and the next guy could make it 5K under 400wtq.

Isn't the 7AT rated at 295ft./lbs stock? I know there's another version rated at 400+, not sure why no one has explored this route unless the OEM TCU's are quite different and one can't control the other.

Yup I asked this a while back in another thread. Nobody seems to know the answer, I even asked Level10 but did not get a reply on this.

I think people do not care because there are already bulletproof 7AT options available if you got the $$$.

These transmissions are $7k+ so you can buy an oem one for $7k+ or you can build yours for $5k...

Which is the better deal?

$7k+ and 400ftlbs limit
Or
$5k and 800+ftlbs limit

He's speaking of a new 7A/T from Nissan, (pt#310C0-X988D)...as much as $8500 tht i've seen,,,They can only withstand 400ft.lbs.Tq. (probably input) & the built 7A/T can withstand 800ft.lbs. for $5,000 Built.
