Jcb 3CX powershift transmission problem?

Hi,
I have a JCB 3CX SUPER from 1998 with powershift trans. The other day i have opened the gearbox to change a clutch pack and, while i was at it, i have cleaned the solenoids too. Now the trans is on the machinery again, i have connected the solenoids but it has the following problems :
- when i select forward the machinery does not move at all
- when is in neutral, the machinery goes backwards (i think in 3rd gear)
- when i select backwards, the machinery goes forward (i think in 2nd or 3rd gear)

What do you think is the problem with this? Is there a certain way to connect the solenoids, or i don't know...?

Regards,
Cristi
