904 Valve Body

The shift valves are burr free and move freely in their bores.
The trans shifts perfectly at slow speed and wot. If the drum seals were leaking wouldn't it be worse at wot? I had the pump clamped in a soft jaw vice with the input shaft and direct drum installed in it. I poured trans fluid in the clutch drum and applied 35 psi of air to the pump and there were very few bubbles in the fluid. It's sealed tight.

I read online that someone was having the same issue as me with ther TF-2 kit, and they called the Transgo tech line. Their answer was that the tp valve in the valve body was to short. How can that be?
I'll call them Monday and see what they say.
