My '79 has a cable running to the general area of the carb but is not connected to anything. I knew it wasnt the throttle cable, and since I have limited capability under the hood, I was confused about the hook up. I have since found out that its the "transmission kickdown cable". I saw one for sale on eBay, so im half way there. Now I just need help connecting it. There is no hardware(i.e. screws, nuts, bolts), so I need help connecting it. Im waiting for a service manual in the mail, but in the meantime if anyone can help me hook it up, I would appreciate it. Heres a picture....http://elcaminocentral.com/albums/Gutterboy1979/1_002.sized.jpg

If you have the correct carburetor for your vehicle, it will have a place to attach the cable to the carb. In your photo, the cable end appears to be far too long for the linkage. However, it could just be the angle of the photo. Do you know if the carb. is the correct model for the engine? If yes, simply attach the cable connetor to the available hole in the linkage that appears to fit naturally. Then, test it to see if it works correctly. If not, you will have to adjust it. Easy to do.

Im probably gonna have to adjust it, cause its about 2-3 inches too long for where I have to connect it. How can I do it, and what kind of hardware do I need?

First, make sure the cable is installed correctly. It may be installed out of position (2 - 3 inches too far forward). Can the whole cable be moved backward 2 - 3 inches?

Second, if the cable cannot be moved backward, I would consider bolting a 2 - 3 inch piece of flat steel to the carb linkage (pick a spot that will work freely and cause no binding from idle to wide open throttle). It would be best if it is bolted to the linkage where the cable should normally bolt up. Drill a second hole in the flat steel to correspond to where the kick down cable connector will line up. Then bolt it up and take a test drive. It should be close enough to make the final adjustment with the large "D" shaped button on the kickdown cable adjustment just behind the carb.

It may be just my vision, but it appears the kickdown cable in the picture is not fully seated in the bracket. It should be a press fit into the bracket. However, that would move it forward a little more and make it that much longer.
Just judging from the picture, it looks like you do not have an original carburetor. When I get a chance to look at my set up, I'll try to post a picture. If I'm not mistaken, the post on which my kickdown was installed was towards the front of the carburetor and below the pivot of the linkage. The end of the cable is close to the post on the carburetor linkage so that when I accelerate (probably more than 1/2 throttle?), it pulls the kickdown cable.
It's hard to explain without pictures so I'll try to take a few soon.
Good luck!

That looks like the kickdown for a 350 or possibly a 400 but I'd bet its to a 350. So you need about 1/4" between the very end of the cable and the stud that will hold it to the carb. That is not the Carb that came on the truck otherwise it would have the stud.

Its a holley and you'll need to get the Holley mounting hardware or from the picture it looks like a holley. You should have it hooked up for lots of reasons but only one reason matters, some of the internal pressures are regulated, so to speak, by the action of that cable. It sort of puts the transmission in neutral and assists the downshift. But it still should be hooked up.

If it was a 200R4 or a 700R4 I would be telling you to go get a new transmission. That connection for those two transmissions is absoultly critical to the transmission working and lasting or going bad in several weeks/months, depending on several factors. But without it, and it being properly adjusted, those two transmission will burn out.

That might not be the carburetor for that car although it looks like a Q-Jet it doesn't appear to have provisions for the kickdown cable so the "installer" left it off. Probably the most efficient way to correct the problem is to get a replacement carb with the provisions for a TH350 kickdown linkage.

I think getting the right carb is my best bet. I have a 267 and i'm not sure which tranny it has. Whats the correct carb for this engine? Ill get the right one then probably sell the one I have now.
