Got my Frog ('74 automatic) started, and happily idling...with the use of a 2 barrel FoMoCo carb off a dirt track car.
The carb has no way tohelp with the operation of this kick-down linkage....and a really, really like the way this carb operates and looks. HELP!!!
side note: I was told that this linkage is a must for an automatic...now how can I get around that?
I've always heard it's a must have as well. It has something to do with maintaining pressure to the front pump. There are cable kickdowns from Lokar & others & if there is no way to get the rod working I'd go that route. It's around $50
Kick down is for passing gear, if it's not hooked up it won't down shift when you stand on it so you would have to shift it manually. GM 700R-200R have the TV cable that controls fluid pressure through the rpm range.

That's also true on overdrive Fords but not hooking up passing gear on C4's will eventually cause slippage in the 2-3 shift. I had one that did just that because I drove it without passing gear connected for a year
Well, never messed with the AOD's so I don't know about those, but I've had many C-4's and C-6's and never had a problem with them not hooked up, as long as the linkage is retracted it don't affect anything, but if the linkage should move and not be all the way retracted then it could be partially in shift mode between 2-3, then you wouldn't have full apply pressure to 3rd gear and would cause slippage.
Unfortunately I never knew enough to prevent it from happening on my truck. My 79 V8 Pinto never had the kickdown hooked up & the 2-3 shift was slipping when I bought it.
Well, it's been over 20 years since I had one and maybe because none were stock had something to do with it too I don't remember now, still don't remember a problem with it not hooked up?, but hey maybe there is, learn something new everyday?..
i`ve had my 429 with a C6 trans in numerous vehicles over the past 30 years including a drag truck for 3 years... never had the kickdown hooked up ... never a problem ....
Guess I wasn't dreaming after all,LOL, my last C6 was behind a 428 in a 66 F150 and it was never hooked up, put some hard miles on it and it always worked flawlessly, wish I never got rid of that truck..
Maybe both of my levers were partially engaged. I assumed it was not having it connected that ruined the trannies

Nope wasn't me never been there was in Socal then, I bought the truck from the original owner had a gazillion miles on it and tired, had a 428 and C6 laying around so it was a weekend bolt in then drove the heck out of it,lol..

That's a good possibility..
I'm definitely thinking it's probably more of a 'if you disconnect it and just leave the linkage rod just laying there' caused issue. I imagine you could have the same issue if the little spring that pulls the linkage up toward the bracket was missing or broken.
I think mine would have died an early death had I not corrected the adjustment. Someone had mine adjusted so far out that it would kick down before the secondary got anywhere near opening (probably done by the po to counter the fact that it was running on 2.5 cylinders when I got it lol). Adjustment also important to check, if it's set to open that early, you'll essentially be driving around with it partially engaged a lot.
My $.02
Very true, if you use it it needs to be adjusted correctly.
So long story, I may be able to disconnect the passing gear linkage-if the linkage gets secured in place?

Apparently so, yes. I would make note of where the kickdown lever is positioned on the tranny & remove the rod entirely & use some stiff wire to lock the arm on the tranny in that location so it can't move.
