727 shifts early

is it maxed at the trans or just the rod?

try disconnecting it from carb and adjust it at the trans full on all the time. take it for a drive and see if that makes a difference.

That is a good question. I just spent hours this weekend heating and bending the shift linkage rod and the linkage to got it to work smoothly. I will have to jack the car up and take a closer look. But what I can tell you is that with the lever diconnected from the carb I can push it until it feels like the lever on the trans is maxed. I will also check to make sure I am getting WOT from the pedal.
