Inching Valve R&R

Hello, Im attempting to repair and or rebuild the inching valve on my 1977 Yale Model# GDP050SANPB086, Ser # P-322527.
Still waiting to here from Pape Equipment local in Reno, NV if parts are even available but I figured I might as well try this forum at the same time. So far I have the valve body removed from the front of the transmission. I was able to remove the brake line plug and plunger assembly from the housing but the other end that is retained with an internal snap ring does not want to come out. So I'm looking for some disassembly help and information on parts, gasket and shop manual availability.
Thanks
Rob
