904 with Turbo Action shift kit, no 3rd

So.., I disconnected the kickdown cable and drove it around, it still shifts the exact same and doesn't ever hit third. I also adjusted the lever to be full back with WOT, and it shifts exactly the same. All the other gears are great, including reverse so I know all the clutches and bands are good.

I hate to pull the valve body off this thing for the 4th time.. its either going to get a $250 pro-stock valvebody with manual/auto capabilities, or I go the cheap route and un-engineer the shift kit out of it and figure out what went wrong.

Does anyone know if a problem in the throttle pressure adjustment would cause this? Any advice will help. Thanks..
