No, you don't. It just makes passing easier. I left my passing gear rod off on my Mustang. When I want to downshift, it's just as easy to pull it into second.------------------

This may sound stupid, but when I did the swap from 240 I6 to 302 in my 68 F-100, the kickdown linkage didn't line up, so I left it off. My buddy who helped me do the swap said I would just have to pull it down to 2nd manually. I babied it for awhile after the swap, so I didn't need the "passing gear", but when I started driving it "normal" I noticed that it still would kick down without pulling it down into 2nd. I understood that without the kickdown linkage, it wouldn't do this, but it does.

you still have a vacuum modulator to control shift points, it just doesn't work as well as the kickdown.
you have to be very early into gear to downshift that way...

My transmission guy says yes you do need it because it regulates the pressure in the valve body. When you floor it you open a passage and increase line pressure to the clutches. To make the valve body work manually you have to wire the kickdown in the passing position or pin the valve in place. I burned up a c-4 in less than 6 mo. behind a 351w by not having one so I belive now. Yes they will operate without a kickdown and yes it is there for a reason. After all, are we gonna argue with uncle Henry? Just my .02c though

never heard of that from a C4, but I've never run one without a kickdown lever before...
