Late shifts after new torque converter.

You will want to install a heavier "Green" Kick Down Linkage return spring as in this picture to pull the kickdown linkage forward as the throttle is closing back down again.

This is a test, put your thumb on the kickdown slider linkage and push it back and and let it return forward again with the tension of the spring.

This action should move freely back and forth by hand. If it is not returning the linkage is binding up and you need to find out why.

This is the way Ma Mopar set the kickdowns up.

Now if you are using a cable kickdown, do you have it set up with a return spring or do you have a 2 cable push/pull setup ??

Not recommended to wire the kick down arm forward at the trans, use the linkage hooked to the throttle with a spring . . so it pulls back with the spring.
