Do u have a manual valve body ? That's what I got Kenny to put
No its not manual. My tranny builder talked me out of it and I'm glad he did. But a manual valve body is cool too

Yea I didn't want it to shift by vacuum reference I want it to shift when I tell it to lol
yea I hear ya. The modulator is adjustable and I adjusted it to hold the gears a little longer. Its almost how the 60 was with a my old nelson tune. I can also shift manually if I want too
