A single handle control for vehicle transmission that includes a body pivotal about a longitudinal axis to move a cable controlling the forward and reverse clutches of the transmission, a control handle rotatable about an axis perpendicular to the longitudinal axis that reels and unreels a tape to move a second control cable which controls the selection of the speed range clutch in the transmission, and a neutral lock that prevents pivoting of said body to actuate the forward and reverse clutches.
Claims11
Improved transmission control apparatus for a vehicle wherein the transmission includes a forward direction clutch, a reverse direction clutch, a clutch for each speed range and has a neutral position wherein neither the forward nor reverse clutch is actuated, and valve means for controlling actuating fluid flow to the clutches, the improvement comprising:
- hollow, elongated, control body means pivotally supported on the vehicle;
- cam means located in said body means and pivotal therewith, said cam means including cam follower means moveable axially in said body means;
- directional control cable means attached to and moveable with said cam follower means;
- transversely extending, rotatable range control means projecting from said body means for pivoting said body means whereby said cam follower means and direction cable means move axially relative to said body means to one of said forward direction clutch, reverse direction clutch, or neutral;
- and,
- speed range control cable means extending through said body means and operably connected to said range control means for selecting one of said range clutches upon pivoting of said range control means relative to the body means.
