I think my 727 is fried. Now I'm at a crossroads...

Adjusting your "Kickdown" should affect your shifting points and sharpness.
Thanks, I know I should’ve made sure it was adjusted correctly already, but I’ll go back and make double sure. I also suspect the kickdown linkage isn’t correct for my car. I had quite a time finding what I think is the correct linkage, so I’m going to get that installed.

When I first got the car, the kickdown wasn’t even connected and obviously it drove like garbage.
