how does 700r know when to shift?

I know that a TH400 shift is signaled by vacumn. How does the 700R signaled to shift. I am swapping out a Th400 for a 700R in my 1962 Chevy pick up. I am alittle concerned about the wiring. I just installed a shift kit, with an optional manual shift only , but opted not to go that route. Will it take a lot of work to make this tranny work properly, shifting, or should I of gone the manual shift route. Which components or steps are vital to its operating correctly? Thanks.......

By the throttle valve cable (TV Cable)...among other things...

Some people call it a kick down cable which it is not.

There are many places that make adapters to common carb's. It isn't all that hard to hook.

It isn't hard to do right (there is a lot of misinformation out there) but setting up the TV cable is critical. Read everything on this link then contact BowTie Overdrives for one of their nifty TV cable adaptors.

T.V setting

bowtie overdrives has a nice site but if in the real world that I rebuild in! You can pull the stock unit rebuild it and still have to reset the tv cable even those that haven't been rebuilt before. I'm not a bubba shop or your brother-in- law just a guy that been doing tranny's along time and just a extra free be
