Hi guys, tried the set up that Joecar mentioned and no luck unfortunately, looked at the shift times and at light throttle we have a shift time of .3sec but not matter what we do WOT shift times are around .7sec
We will try and make a few mechanical changes to the Trans but from memory the VZ already has a small servo piston for the band so will have to look at the accumulator side of things (which from memory might not even have a spring!!!) and maybe the valve body plate holes, has anybody done these changes on a VZ???
Times like this a really wish GM had a pressure test port for the band servo
