Yes, remove the access cover on the tunnel Soak both ends at both pivots with penetrant. Grab the linkage rod with vice grips through the opening and begin to move it back and fourth until it operates freely. Occasionally, turn the ignition on and see if the rod moves when the accelerator kick down button is depressed (under the pedal). When working properly, the rod will move rearward when the engine is running at idle, it will then move to the center rest position when the accelerator pedal is slightly depressed, It will move to full forward position when kick-down is engaged. When engine and ignition is off, the linkage should move to center "rest" position.
