I've narrowed down the "suspected" source of the shift problem and would like some corroboration as to whether or not I'm in the right field, I'm hoping that it's only a matter of cleaning the valve spool and the oil passages inside the shuttle control valve housing. Upon removal of the vent on top of the housing I noticed a lot of grit inside due to a collapsed screen filter which I'm thinking that the dirt is hindering the directional flow of oil to the forward/reverse shuttling.

Haven't got into it yet but I'm hoping for next week...I'll give a status report.
