my trans is Slipping @ WOT on the 2-3 shift as soon as the rpms hit 6500 it slipping almost like its free wheeling or wants to shift but slips instead

This indicates the direct clutch isnt holding and is probably already damaged.I f the oil is clean and the clutches are not hurt try this http://www.turbobuick.com/forums/transmission-talk/322203-3-2-control-valve-mod.html

transmission only has maybe 150 miles on it , i changed the fluid last week before any of this started and it was very dark , i'm sure it already has that mod you posted a link of , but i dont know for sure .

what would cause this ? TV cable too tight ? too loose ? builder lack of experience ?

can anyone tell me the cause of this so it doesnt happen again .

The cause is usually the 3rd clutch is slipping.This is 1 area where the stock or unmodified direct circuit has issues.Put on a gage to read pressure or pull the trans and have it inspected and repaired.
