How much hp did your stock tranny hold before you had to upgrade it ?

PEETYZ

Really depends on what you do with it. Lauches are hardest on it. I would recommend upgrading around 600rwhp or so either way for piece of mind. A trans/diff brace will help quite a bit as well and is a must with the T56.

There are stock units holding 700+ but they usually are not launched or driven too hard. What is your setup/goals?

I have a built RPM T-56 for sale if your interested. Link
