In most GM and Ford transmissions with cables, the throttle valve cable pulls out of adjustment at wide-open throttle. This is typically caused by inaccurate geometry of the throttle shaft lever. There should be a specific degree of movement of the attachment element pivot point between closed and wide open throttle. There also should be a specific distance between the pivot points of the attachment element and the throttle shaft lever. When either of these two distances are greater than the spec, the TV cable will be pulled out of adjustment.
Sonnax TV cable corrector kit AS1-01K prevents the TV cable from being pulled out of adjustment at full throttle by allowing the spring to compress and absorb any excessive cable pull. A quick and inexpensive fix for any transmission with a TV cable.
