problems with kickdown shift RPM

The governor weight and spring determines the maximum shift rpm. No matter how you adjust the throttle pressure linkage the governor over rides it when it reaches it's determined rpm. You just need a higher RPM governor shift package. Here's a link to the governor package page on A&A. You'll see they come in several different RPM packages. You'll see it's listed under a 727 trans. but their the same until you get into the late 80's-90's diesel stuff
