Max power AT in all gears?
 

Apologies if this has been answered. I am looking at turboing my 370 A/T and would like to know what RWHP limit exists when it comes to the auto. From what I have read the automcan handle a decent amount of power up to 4th but 5th to 7th is slips. My question is, does anyone know what the max power is the auto can handle through all gears?

The build I am looking at will be 390 to 400rwhp single turbo.

Thanks in advance.

If I were you Id get a tranny cooler to be on the safe side. mb a transmission upgrade. I think 400rwhp is pushing it for the 7at transmission.

Any tuners or people who run FI know the A/T limit? I agree, the cooler is a must.

I am not new to turbo builds so I am trying to figure out what my options are when it comes to the tranny.

Thanks!

Go to GTM's website, they have options for tranny builds. I'm not experienced but I'd say at least a tranny cooler and valvebody upgrade. -after that it gets expensive. Get a FX45 transmission and stuff that in there.

The said limit is 440rwhp by nissan. The true limit is 400rhwp. I am going the FI route as well and found that the best thing to do is swap the high gear cltches, get a valve body upgrade and transmission cooler. GTM sells parts as well as complete AT upgrade kits. There lowest is kit is $4600 but may still be OD for a 440rwhp build?
