    I guess you have a point there. At the time, mine was my daily driver AND my street toy. But I can see that in a case such as a new driver, passing gear would be a necessary item. Preston

    kickdown rod

    hey country mav the kickdown rod increases throttle pressure to oppose governor pressure to control upshifts there are certain shift points recommended by ford . no throttle linkage should make the car shift too soon too long a rod will cause the trans to shift too late as it increases throttle perssure and the governor has to overcome that pressure before it can upshift

    Never heard that. What I've always heard was that the rod works when you open the carb up past a certain point, kicks it down to 2nd (passing gear) without you having to manually shift it down. Never heard anything about it help setting the shift points. Anyone else heard this? Just curious.:hmmm:
    I know you can adjust the throttle shift points with the modulator, as that's how I've always done it and I've never ran a kickdown lever.

    Ahhh, I see. I shift manually (even though it's an auto) :rolleyes: so I never worry about it! :D Preston

    I have never heard that before either. The kickdown rod is just that, a kickdown rod. Most beefier engines that require a stall convertor cant use them because when it kicks down it will actually come off the convertor and then bang up against it which is one thing you dont want.It can cause you to either lose traction or serious damage to your tranny. So if you are running a high stall dont use it.

    Now i think the kickdown rod he may be referring to is the little rod behind the modulator valve in the tranny. You can change springs and rods to control the trans pressure to make it shift at different points of rpm, But now they have ajustable modulators thru most aftermart performance stores so you dont have to mess with the rods anymore.

    No, he is correct about the kickdown rod. It is connected to a spool in the valve body that delays upshifts and "suggests" downshifts, based on load and rpms. It's not a direct link to 2nd or 1st gear, it just re-directs fluid. If you are going 80 and mash the pedal, it won't downshift into 2nd. If you are going 50, it won't downshift into 1st.

    Still never heard of this, and I've seen many C4s and C6s apart

    Have you noticed what the kickdown rod is connected to?

    Yea, I notice that.
    But you don't HAVE to have that rod.
    I've never ran it, never had a problem.
    Its not part of the shift process really.
    Its more of an option for granny type drivers.

    I see both sides of this, but don't agree that it has anything to do with upshifts

    No, you dan't HAVE to have this rod. Most people that don't have the rod do a fair amount of manually shifting their automatic, which is what I do in my Mustang with a console, but that is a little inconvenient for those of us with column shifted Mavericks.

    The rod moves a kickdown spool which redirects fluid to the 2-3 shift valve (or 1*2, depending on speed) and hydraulicly forces a downshift. The same hydraulic pressure that forces the downshift also delays the upshift until fluid pressure overcomes spring pressure on that particular valve.

    Not a big issue for most, but that is the way it works, as far as I can tell. I looked in the manuals to see if they explained it, but Ford chose not too. You have to look at the valve body schematic to see it.

    Interesting to note that the transmission section in my 69 manuals and my 77 manuals were almost word for word the same.

    thought this was cool too!

    btw i heard some things about a duel outlet header on a maverick.. some say it won't fit. then again those are mustang guys. something about the starter or something. i seen one on a maverick b4 but never bothered to ask the guy what he did since i never thought i'd own an i6. true? untrue?

    All that carb and you still have to deal with the log style 1 barrel intake.

    I think Clifford makes a kit for machining for multiple carbs.
