Hi, just a quick question, have just rebuilt a ford c6 to go on the back of a ford big block, and have installed a manual shift kit in the valve body, do i still need to give the modulator a vacum supply, or can i blank it off?

Cheers

Cant see why u would need it as the vacuum controls " drive " which you dont have...right to ask the question tho if you are not sure
dont take my word on it ask redvictor i'm sure he will know

I'm not 100% sure but I think you probably still need it. I think it may affect the line pressure as well as the shift points.
