  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.

  Q: How to remove and install the Throttle Cable?

  A: It has the cable type of throttle control system that does not have any linkage adjustments; hence, only a specific replacement part would work in this case. When working on the throttle controls, care should be taken to restore all linkages and cables as they were removed and to ensure there is no rubbing or binding. Servicing the throttle cable calls for retention of the retainer with the tangs secured over the head of the stud, expanding and locking down the locking tangs in the conduit fitting at both ends of the cable into their attaching holes, ensuring that braid doesn't touch dash sealer on front side during assembly, repair or replacement and avoiding routing flexible parts within 2" of throttle linkage moving parts outward of support bracket unless routing is positively controlled. Servicing the accelerator pedal requires that there be no insulation between mounting surface of support and dash panel, while carpet and padding must be laid flat without wrinkles or bunching in pedal and tunnel areas, slipping the throttle control cable through orifice in rod slot and then installing retainer on rod (ensuring that it seats correctly and keeps cable from getting kinked or damaged) as well as operating freely without binding throughout closed throttle to wide open throttle travel when all components of acceleration linkage are secured. Removing it entails disconnecting battery negative terminal cable from it's terminal post, removing air cleaner housing adapter, locating forward end of throttle cable at engine; popping retaining clip on end of throttle linkage stud loose with a small screwdriver; detaching retainer from throttle lever stud; disconnecting throttle cable from notch on throttle valve; pinching two locking tabs together on ferrule pulling cable through hole in bracket; locating upper end of accelerator pedal lever by pushing small plastic brush out top; pushing lever forward lifting cable free from slot in top of lever; positioning soles immediately above and ahead upper end where comes through firewall: pull large rubber washer loose pinch locking tabs together pull cable through firewall; finally, installation is the reverse of removal.
