if im understanding how these things work correctly, the governer is what controls shift points, and it can be manipulated.Ha! VD.. I'm kinda looking into the silverfox VB, not the constant pressure but the spt1. The description says one can adjust shift points in 800 rpm incraments via a screw on the vb. I'm not quite understanding this really since I thought shift points in the aod were controlled by the TV pressure. I'm not much of a tranny guy at all, its all foregin to me. But I do hear that Tranny's have VD. Oh one more thing, do y'all think the entry level silverfox or any for that matter are worth the 270 bucks? I mean after all all they are are a tweaked used stocker. One could buy a pa street/strip for a little cheaper or for a good deal cheaper you could buy a shift kit and put it in your vb yourself. Would it not be the same thing? I don't have any experience w his product or know anyone who does so I'm not bashing it I'm just curious. The reviews on other forums say its pretty good,(save for one I've read) but I haven't read where someone had a cheaper shift kit and then switched to the silverfox and said that the fox blew the transgo outta be water for example. They were only comparing it to a worn stocker. Oh and allegedly the silverfox comes from the "factory" set to shift at 5800 from 1st-2nd
as far as an already modified vb (doesnt matter through who), you gotta remember that taking your car somewhere and having a shift kit installed is gonna cost about $300 (or more) in parts/labor. add in that the silverfox ones are basically custom built for your application (4r gearing in aod, custom shift points/firmness), and its really not THAT bad, but yes, there wont be a huge difference between it and just putting a shift kit in for the untrained eye.
