In GM 4L60 units, the TV cable synchronizes engine throttle movement with TV plunger movement. If the cable is not readjusted to ensure proper line rise, the unit may return quickly with soft shifts and a burned 3-4 clutch or band. Sonnax shortened TV link 77872-01 is shorter than the OE so that the installer must readjust the TV cable.

  • Soft shifts
  • 3-4 Clutch failure
