5hp24 rebuilt issues

[fmugur]

As a few of you here know that I rebuilt a ZF tranny following the manual and with help from other members that were succesfull but something didn't go well for some reason with my rebuilt. I might have overlooked something in my rebuilt process.
So, the first gear is fine, the reverse is ok too but when I put it in D it does not change gears and it is actually trying to stop when it supposed to change. If I put it in the second gear manually after the first it it stopping very harsh to the point that it will brake something. If I start in 2nd it revs and it seems like part of it is trying to move the car and another part is stopping it.

I have the old tranny out I removed the valve body so I can see inside. It looks like moving the output shaft it moves the D/E brake in one direction only and not the other and the A/B clutches move only when I rotate the output shaft on the opposite direction.
Now, I don't remember how my rebuilt tranny behaves but I don't recall being the same as above. I might be wrong though and it might not be even possible but I think I could move the D/E brakes in both directions from the out out shaft.

Could the problems I have be related to the valve body only? I guess I can try to clean the VB that came out from the tranny that I just removed and swap it on the rebuilt one. But is it worth the effort?
I can remove the rebuilt tranny from the car and compare the behaviour of both on the floor and then disassemble both and compare.
Another option is to rebuilt the one I took out and swap it but how do I know if I don't run into the same problem again?
