  Q: What does the throttle valve cable control on these transmissions?

  A: The throttle valve cable used on these transmissions is not just a "downshift" cable, as it controls various aspects of the transmission's operation. It regulates line pressure, shift points, shift feel, part throttle downshifts, and detent downshifts. If the TV cable is broken, sticky, misadjusted, or the wrong part, the vehicle will experience several problems. To inspect the cable, remove the engine cover and have the engine running at idle speed with the selector lever in Neutral. Set the parking brake and block the wheels for safety. With an assistant applying the brake pedal, grab the inner cable a few inches behind where it attaches to the throttle linkage and pull it forward. It should slide smoothly through the cable housing without any binding or jerky operation. When released, it should return to its original location with the cable slop against the cable terminal. If the TV cable does not operate as described, it is likely due to a defective or misadjusted cable or damaged components at either end. To adjust the cable, the engine should not be running. Depress the re-adjust tab and move the slider back through the fitting away from the throttle linkage until it stops against the fitting. Release the re-adjust tab and turn the throttle lever to the "wide open throttle" position, which will automatically adjust the cable. After adjustment, check for proper operation.

  Q: How to remove the cable?

  A: To remove the cable, start by disconnecting the cable from the negative terminal of the battery. Then, lift off the engine cover and remove the air cleaner housing to gain access to the TV cable end. Disconnect the cable terminal from the throttle lever by pushing it forward and then off. Push in on the re-adjust tab and move the slider back through the fitting away from the throttle lever. Compress the locking tabs and disconnect the cable assembly from the bracket. Raise the vehicle and secure it on Jackstands. Release the cable from the mounting clips, noting its routing. Remove the screw and washer securing the cable to the transmission, and pull the cable up to disconnect it from the link at the end. For installation, place a new seal in the transmission case hole. Connect the transmission end of the cable to the link and secure it to the transmission case with the screw. Tighten the screw securely. Route the new cable and secure it to the mounting clips. Pass the cable through the bracket and secure it with the locking tabs. Connect the cable terminal to the throttle lever and adjust the cable. Finally, connect the negative battery cable and check for proper operation.
