I had my Stage 1.5 kit on my 2010 sport/touring 7at with 470 rwhp you will need a 25 row trans cooler (mine had a Spal 6.5in electric fan)and you should strongly consider at least a
VB upgrade and if funds allow it a stage 4 trans from GTM.
The reason I have a Nismo now is b/c the trans started slipping 6 months after install with some pretty hard abuse.
