I'm building my 2nd 4L60e Trans. This is going behind a '97 LT1 5.7L that I just got back from the machine shop. This Trans. had a 10 vane pump in it, I have a complete 13 vane pump in my spare parts bin. Which would be best to use for this build?

I did install a normal orange box Transgo Shift Kit and a Blue box Transgo .500 Boost Valve/ Springs.

Still learning as I go.
