Fresh Turbo 400 issues

Fresh Turbo 400 issues
Freshly rebuilt Turbo 400, has reverse and 1st gear only. Those gears are tight and not slipping. Will not go into 2nd gear, at about 4K rpm I let off the throttle, feels like it slides into 2nd but then it just freewheels. If I manually shift back into 1st it bites and works fine. Vacuum modulator has vacuum and no fluid in the hose. My trans guy thinks (hopes) its the valve body and is sending me a new one.
Anybody have any other ideas or do you think my trans guy is right about the valve body?

its adjustable but still no change. the valve body is a manual/automatic unit so even if the modulator was not working I should beable to manually go through the gears. kinda sucks, he is sending me a new valve body. if that does not fix the problem then I have to pull the trans back out :evil:

sorry... i thought you said you could shift it manually and it worked ops:
did you check to see if the trans filter is locked all the way in cause if it will cause that very same problem cause its sucking air!

The valve body is out, now just wait for the new one to arrive and pray it works.
