I run the older version Turbo Action 17676 Auto/Manual Valve Body on the street in my 71 Bee

My Low/Reverse uses the heavy duty spring that came with the Valve Body

The newer Turbo Action 17876 Auto/Manual Valve Body doesn’t use this heavy duty spring per instructions

Has the auto shift feature or shift manually

And uses the factory kick down linkage

I just installed one in my friends car in fall

Anyways


I had the chance to talk with Randy in detail about this when I bought my billet servos from him thru email , what is the difference between both valve bodies , old and new

Man , what awesome customer service a few years back by the way

He wanted to know what exact valve body I was using because he said the newer 17876 Valve Body uses these two bleed holes in the picture , hence eliminating the need for the heavy duty Low / Reverse spring


My 17676 Valve Body did not have both of these bleed holes

I am not a Transmission expert hence my questions when I was buying his billet servos and installing my Turbo Action 17676 Valve Body that was still new in the box , never installed , that I bought from a local guy

And yes I am running the factory kick down linkage with this 17676 Valve Body

And yes the Valve Body has the auto shift feature with part throttle kick down
