Is a Dynaflow supposed to have a kickdown like most automatic transmissions? I asked the guy that owns this Buick I am working on right now if his kickdown worked before. He first asked me what a kickdown was and after I explained it to him he said it didnt shift back when he hit the gas. I seen a linkage when we were taking it apart but am not sure what it is for. I am also thinking that a linkage is missing on the carter carb he has. Can somebody look at the pictures and tell me what the linkages are for and if there is something missing? In the first picture I know that the one on the bottom is the gear selector but I am not sure what the one is at the top. Thanks.
