holley throttle linkage

i have the slide type kickdown not the ball type. honestly thats less of a priority than the throttle itself. i drove my z28 with no kickdown for 2 years, when i needed to downshift i did it haha.

It's not a 'kickdown', it's a throttle pressure linkage which applies gradual pressure inside the trans as you accelerate.

Without the throttle pressure linkage hooked up and operating properly....you will be rebuilding the transmission very soon.
