What is the purpose of it? I pulled it out as far as possible and the car was a slug, but when I pushed it back to where it was, the car shifts harder and feels significantly faster.

What is the purpose of this and why does it feel so slow and shift so high at normal cruising, when it's pulled all the way out.

You guys know what I'm referring to? It's the little black cone thing that holds the throttle cable on the TB, and on the side of it, you can place your finger or thumb on it to depress it and move it in and out.

 

Your not adjusting the throttle cable it the TV cable for the trans!

If it is not set correctly u can fry your trans in short order.

I suggest hitting the tech article for a how to to set it properly or search for the subject looking for posts by vader or pro built
