1964 225 Slant Six with Replaced Electronic Ignition but with No Kick-Down on Torqueflite

I hear and see what you are saying, so let me restate my issue.

The Torqueflite Transmission goes through all three ranges smoothly. However, there is no Passing Gear (downshift range) when you stomp on the throttle as it used to have, nor does the Torqueflite Trany automatically downshift when going up a steep hill.

What might be the obvious problem after the Shop installed an Electronic Ignition System (I noticed there is no longer a vacuum advance outside the distributor housing.)

Thank you for your patience with me and my Shade Tree Mechanic explanation of the issue!

Thanks for that. But my original description is still correct. What you don't understand is this. That linkage is not "just" for kickdown and "passing gear". The correct name is throttle pressure linkage. See, unlike Ford or GM, that linkage DIRECTLY affects the line pressure in the transmission. Push more on the gas pedal and the linkage gives the transmission more line pressure to hold the clutches together. Without that, you will burn up high gear first, followed by 2nd and finally 1st.....and it does not take long to do it! So DON'T drive it anymore until you get that linkage installed and adjusted correctly.
