D6C won’t move

I’m trying to fix a D6c that won’t move I cleaned the inlet screen and changed the filter I have 350psi at the filter and 100psi at the speed clutch and basically nothing at the directional clutch port I took the speed clutch/directional clutch valve off and found a spool that blew apart so I changed the spool and still have the same pressure and won’t move where else can I check I’m thinking it’s a relief valve that splits to the torque but don’t know where it is or how to check
