727 Kickdown Linkage Adjustment - HELP!

The best way to adjust the kickdown is to have someone sitting in the car with the gas pedal all the way down like if you were to floor it. Then with you under the hood adjust the kickdown so it is all the way engaged when the pedal is floored. You may need to fine tune it a little bit but not much, your shift points with regular driving should be 10-15 and 20-25. At 60mph you should be able to floor it and it will smoothly kickdown.
After messing with the 3 types of factory mechanical kickdown set ups I have found that they are all crap, look ugly, and should be sold or thrown away unless your doing a factory resto. Lokar cables are the way to go!
