    C6 transmission not engaging

    Yo diy, No. Manual shift valve inside transmission pan not connected or stuck. see https://www.ford-trucks.com/forums/1513688-how-to-remove-86-f150-c6-initial-shift-linkage-arm-from-shaft.html

    Yo, part deux, NOTE: If automatic transmission fluid is present in the vacuum side of the vacuum modulator or in the vacuum hose, the vacuum modulator's diaphragm is leaking and must be replaced. by Ford C6 Description & Operation, Adjustments, Diagnosis & Testing (partial), Disassembly & Assembly, Parts Break-Out Diagram, Hydraulic Control System Diagram, Removal & Installation & Specifications @ http://web.archive.org/web/20090529064029/http://www.thedieselfiles.com/Ford/C6%20Automatic%20tranny.pdf
