This needs to be done when opening the 2-3 feed and band release holes with 1996 and later valve bodies. With the Corvette servo and running .020" - .035" 3-4 clutch clearance, the band release hole should be .099" - .101", and the 2-3 feed hole at .135" Max.
With the Sonnax servo and running .020" - .035" 3-4 clutch clearance, the band release hole should be .104", and the 2-3 feed hole at .140" - .157". With the Superior servo we have run the 2-3 feed hole at .187" and band release at .110" for years in a couple of vehicles.

Should I block the 3-2 control valve also?

got my car back today - SUCCESS!
Very pleased with it now. Fluid flushed, fresh filter, new 1-2 accumulator piston and enhanced spring and all working fine now! now more weird shifting!
thanks for the help and advice.
