The TV cable MUST be installed and connected to the throttle arm and adjusted properly for the transmission to operate properly. Failure to do this will result in slipping shifts and poor performance and will eventually result in transmission failure. Cable brackets and cables are available on Jegs or Summit to enable proper TV cable geometry/travel.
Adjustment is easily done once the cable is properly installed, press in on the side of the adjuster body (a button like thing, its metal) on the throttle end and push the adjuster all the way into the adjuster body. Release the "button" and slowly open the throttle completely by hand, it will be a bit tight doing so. The adjuster will come out of the adjuster body to the proper distance, and you're all set.
