Typical Automatic Transmission Kickdown Linkage

 

Throttle pressure linkage adjustment (FSM)

  • Make sure the engine is warmed up, the choke is off and the carb is at curb idle.

  • Hold the transmission lever(#11 in the pic) firmly forward against its stop while performing adjustments during the next few steps

  • Put a 3/16" diameter rod (#9 in pic) into the holes provided in the upper bellcrank (6) and lever.

  • Adjust the length of the intermediate transmission rod (#10) by means of threaded adjustment (#2) at upper end. The ball socket (#2) must line up with the ball end with slight downward effort on the rod.

  • Assemble ball socket (#2) to ball end and remove the 3/16" rod (#9) from the upper bellcrank and lever.

  • Disconnect the clip, washer and return spring (#13) then adjust the length of the carburetor rod (#12) by turning the threaded adjustment (#1) until the rear end of the slot touches the carb linkage stud without exerting any forward force on the stud.

  • Reattach all of the springs and clips and check for freedom of movement by grasping the linkage rod (#12) and moving it completely rearward. Let it return, making sure it goes fully forward without binding.
