What is a transmission kick down cable?

Do you need a transmission kickdown cable?
On the OD transmissions (700R4, 2004R, etc.) the “kickdown” is NOT that. It’s a TV cable, which operates the Throttle Valve inside the transmission, and is NECESSARY to be installed and PROPERLY adjusted so you don’t burn up the transmission.
Where does the kickdown cable attach?

How does a throttle valve cable work?
The throttle valve cable’s function is to transfer the movements of the throttle at the carburetor to the throttle valve plunger in the valve body.
