Early 70's A'904 Torqueflite downshift

Check adjustment at kick down lever on trans. Move lever until you start to feel spring tension and lock the linkage down. Just my .02.

Good advice. Correct throttle pressure valve setting will be set so that at wide open throttle against the carb linkage stop you won’t be able to push the slotted adjuster back any farther and it will still have spring pressure holding it against the throttle linkage pin at idle. If this isn’t happening, it’s usually because of non stock or damaged linkage.
