I know its all ballpark, but I'm looking into getting my trans capable of holding 600 RWHP... RELIABLY!!

An ATS trans that can do this is 6-7k just the tranny, there is a place here in Maine (New England Transmission) that has a set-up that will hold my power numbers no sweat and thats about 6k installed, I just don't know what a fair price is... can anyone get me in the ball park?

You can hold more than that for around 4k.

I am into my trans for about $3K and it will hold that power all day long.

you can get into a PPE kit for a lil under $3K if you install it yourself
