ABSTRACT OF THE DISCLOSURE A remote master shift control mechanism (50) for mechanical shifting of a remotely controlled manual transmission (T) by applying a rotational (24) and an axial (22) motion to a connecting rod (20) operatively connected to the shift shaft (36) of the transmission is provided. The remote master shift control mechanism includes a master shift lever (66) which is attached to a master control shaft (54) by means of a clevis joint (81). The master control shaft is mounted in a control housing (52) for axial movement along and rotational movement about its axis (56) and includes at least one end (58) extending from the housing for operative (112) connection to the connecting rod. The control housing (52) defines a slot (86) extending substantially parallel to the pivot axis (80) of the clevis joint connection in which a bulbulous portion (98) of the shift lever is received and through which the bulbulous portion may travel upon movement of the shift lever in a plane containing the pivot axis (80) to apply a joint rotation to the shift lever and control shaft. The bulbulous portion is engageable with contact surfaces (88, 90) defining the slot (86) to define a reaction pivot point for the lever (66) upon movement of the lever in a plane containing the axis (56) of the control shaft (54) whereby movement of the control lever (66) in a plane containing the axis (56) of the control shaft will impart an axial movement to the control shaft. A crank mechanism (112) including a crank lever (114) adjustably mounted (120) to the end of the control shaft (54) may be utilized to operatively connect the control shaft to the connecting rod and to maintain the axis (134) of the crank lever (114) substantially perpendicular to the axis (110) of the connecting rod (20) for various positions of the control mechanism relative to the connecting rod.
