Ian,
 
Found this post late.  I'd do the backwards spool valve test.  Raise the gear on jacks and reverse the switch  at 80% gear up.  If pump does not immediately (less than 5 seconds of silence) reverse and down the gear your spool valve is probably in backwards.  It's a minor headache to reverse.
 
Reversing mine removed a little quirkiness including an occasional inability to raise the gear.  I have no pressure gauges to confirm that it allowed the bleed off.  (Too heavy-costs kts you see). But, there is a hole in the spool valve and I have some recollection that that hole is where the pressure bleeds to atmospheric on the unpressurized side.
 
The horses mouth is Ed Van Hecke at Oildyne (763-531-3578).  Would love to learn from you experience.
