Trans Kickdown Linkage Guru Sought

It is the weight of the Governor piston more than spring. The heavier the piston the less centrifugal force it takes to open the passage for the shift while in the kick down . This causes an early shift while flat out. . The lighter the piston the longer it holds the gear. This only controls the shift in kick down mode. These light governors only came on 340's and max wedge/Ram chargers, Can easily be made out of a heavy one. I have some for pics if needed. You only need to lighten it up.

The part throttle servo down shifts the trans when ever it feels a load or pressure change under pull. I loved putting these the on north east muscle cars back in the day. They did not come with this because of uncontrollable tire spin on slippery surfaces. This an easy addition to the valve body it is only 3 screws.

cool, thanks, that was the last thing in line that i could think of, was governor springs. ive had similar escapades as well with kickdowns. my holley 4175 spreadbore that was sold in the aftermarket world needed the holley adapter to work with the 3 piece kickdown, 318/904, but didnt with my chrysler, 400/727 with a one piece rod. Then on the flipside my 600 cfm 4160 from a 289 ferd, doesnt need any adapter at all...
