Default TH400 going forward in all gears

I just rebuilt my first transmission a th400. Now I have it installed and it goes forward in all the gears except park. It does not seem loaded down when I rev the engine while its in park, What did I miss or do wrong with this rebuild?

You need to make sure that the manual valve is connected to the rooster comb. This is connected to the shifter linkage shaft. Vince

what vince is sayin on the manual shaft there are a groove and 2 lands the tit on the shifter detent has to be in those grooves also you may have not put the pin back through the shfter sgaft from the front side of the pump and it may have walked itself off the tit.

Vince you were right, the manual valve was not connected. It is now and working good, thanks for your advice.
