I have a 1979 P337H
I am having a gear retraction issue

After take off, I raise the gear handle, the green light goes off, but the gear doesn’t retract
If I lower the gear handle, the green light stays off
If I pump the emergency gear handle once, the green light comes on again and then if I raise the gear handle again, it cycles normally

And if I cycle it over and over , it works normal

I have had it in the shop twice
Fluids all good
Cycles normally when plane on jacks

Appreciate any thoughts
