Shift Kit for a 727

To set kickdown correctly, the throttle (upper) lever on the transmission must be all the way back to it's stop with the throttle wide open. You can add slack back into the linkage to soften shifts if need be, but be careful.

So, do you want a fast positive shift, or a screech-bang clunking lurch that will beat the crap out of your motor mounts u-joints and tranny?

Heck, you can always just crank the line pressure up all the way. Might cost you a couple MPG, but things will go bump in the night.
