    Hello to you Maverick fans. I hope I am in the right place, here.

    This 1975 engine (D5DE-9C485-BYA) and Motorcraft 2150 carburetor (D5DE AFA) were original equipment on a Maverick or Granada built that year. They were either in a manual transmission vehicle or the carburetor's throttle lever was subsequently tampered with - it is missing the attachment for the kickdown rod which is needed with an automatic transmission. The kickdown rod is also missing.

    I have been unable to find the part number for the kickdown rod or for the part that attached the rod to the throttle lever, so I have not been able to even begin to search for the attachment part, or the rod. I am hoping to find someone who can provide the part numbers, and perhaps even a source for the parts. [FONT=trebuchet ms,arial,helvetica][/FONT]

    Doubt you'll need the part numbers. Just post a WTB in the Classified forum here. It that doesn't work, try www.sbftech.com or one of the Mustang forums.

    Thanks for this image, which has numbers on it. I'll do some more research, and see how far I get with them. I see the rod is shown as 7A187, which is different than the #'s 7A186 & 7A816 I've seen on other diagrams and gotten nowhere with. I do have to questions about how to use these numbers.

    Are these full part numbers, or do they need to be combined with some assumed known prefix or suffix to be used in part location?

    The diagram shows the downshift (kickdown) rod with another part (7B146) and a fastener 383212-S (GG-362). I'm hoping there is no additional piece needed for the connection or adjustment which the diagram omits because it is assumed to already be on the carburetor throttle lever.

    I think should go ahead & get these, if possible, and see if they include everything needed to both fasten the rod to the throttle lever and adjust the kickdown to match the throttle position to the downshift action correctly.

    I tried to insert a photo of the kickdown attachment, as it is on a MC 2150 carburetor set up for automatic transmission, here, but it did not show in the preview, so here is the link:http://s931.photobucket.com/albums/...150-ATCarb_KickdownAttachAdjust_X6-289-01.jpg

    Draconian Alternatives

    So far, it appears that the part in question, which would accept the kickdown rod, is an integral part of the carburetor, and not a separate part. If I understand the feedback I've received, the kickdown attachment point is included in the assembly of the throttle shaft, and is a part of the assembly stamped into the unitary throttle shaft & lever. No stock part can be added, to convert a manual transmission carburetor to one that works with an automatic transmission.

    This leaves me with draconian alternatives:

    • trash this fine carburetor and hope for the best when purchasing a replacement built for automatic transmission application;
    • try to find a dead carb for an automatic that has a usable throttle shaft with the necessary part on it, and swap the old shaft out;
    • set the throttle to prevent acceleration and engine loading that would result in a need for kickdown;
    • try to find an aftermarket "attachment" that could be bolted to the throttle lever and used for a kickdown rod receiver;
    • have the transmission mechanic fashion an informal kickdown rod and attachment system;
    • this excellent idea from a friend - trash the C-4 automantic and get a junkyard manual to replace it; and finally -
    • purchase one of those "manual automatic" valve bodies and convert the C-4 to full manual operation - presuming that this eliminates the need for kickdown.
    What do you say, folks?

    Post in the wanted section what you want to buy. If the carb in the photobucket pic is what you have then it looks like all you need is the rod which I am sure someone will have.

    Ok, I reread the first post. Someone will also have the carb you are looking for. They also sell them at parts stores.

    Maybe some pictures of my '72 carb with auto kickdown lever will help. That part does appear to have been manufactured integral to the throttle shaft.

    Sorry for the fuzzy focus. My camera doesn't do closeups well. Says its focused but its not.

    Can't you just pick up a used correct carb and rebuild it? Gotta be a lot of them around that have been replaced by 4 BBLs.
